Release Strategy
This page describes the "who", "what", and "when" of Pants releases. If you're interested in learning "how" to release, see the Release Process page.
Release Responsibilities
There is one release manager per week, decided via a shared calendar (to volunteer to be added to the calendar, see How to Contribute).
The release manager is responsible for:
- Creating
stable
branches - Creating and gathering feedback on release candidates
- Cutting
dev
andstable
releases
These release types and responsibilities are described below.
Release Cadence
The release manager for a particular week decides whether to cut stable
release. A dev
release
or rc
release from master should happen every week. Stable branches will be created based on the
following criteria:
- Decide whether to create a new
stable
branch:- If it has been approximately one month since the
previous
stable
branch, the release manager should inspect the changes in the current release milestone, and decide whether changes that are still open justify delaying thestable
release (this is intentionally left open for discussion). If thestable
release is not blocked (in general, we should bias toward creating stable releases frequently), it will be made from either amajor
orminor
stable branch (described below). - If a new
stable
branch is not created (because of insufficient time/change to justify the stable vetting process), the release manager must cut adev
release from master instead.
- If it has been approximately one month since the
previous
- In addition to any
dev
release or newly-createdstable
branches, the release manager should determine whether any existingstable
branches need new release candidates by looking for changes labelled needs-cherrypick. If there are requests "sufficient" to justifypatch
releases for existingstable
branches, the release manager should cut release candidates for those branches.
In other words, for a given week: one of either a dev
or rc
release will be created from
master. A new stable
branch may be created, and additionally, patch
releases for
existing stable
branches might be created.
Release Types
dev
releases
dev
releases are releases that occur directly from master, without the additional vetting that
is applied to stable
releases. They help to ensure a steady release cadence from master by filling
in the gaps between the (generally more time consuming) stable
releases.
stable
releases
stable
release cycles generally happen every month, provided that there are enough user
facing changes to warrant a new stable
release. For each release candidate for a stable
release,
five business days should be allocated to bugfixing and testing by pants contributors on a release
candidate announcement thread (described below). If any changes are needed to the stable release
based on feedback, a new rc
release will be created from the stable branch.
major
and minor
stable branches
The decision to create a major
or a minor
stable branch is based on consensus on
pants-devel@ as to the impact of the changes.
major
releases signify large or breaking changes. minor
releases however should be compatible
with the last five minor
releases (see the deprecation policy).
patch
stable Releases
In order to allow us to react quickly to bugs, patch
fixes are released for stable
branches as
needed and should always consist of fixes or small backwards-compatible features backported from
master using the needs-cherrypick label. These releases update the patch version number, (ie, from 1.0.x
to 1.0.y
) and should
only include commits that are deemed to be backwards compatible.
Naming conventions
stable
naming
Leading up to a stable
release, development work should be done on a branch named with the
following format: n.n.x
where n.n are the major
/minor
version numbers and "x
" is a literal
character placeholder for the patch
version. Release candidates of an upcoming stable
release
are suffixed with rcN
. For instance: "the 1.1.x
stable
branch",
"the 1.1.1rc0
release candidate", and "the 1.1.1
stable
release".
dev
naming
dev
releases occur between stable
branches, and are differentiated by a devN
suffix. The pattern
to follow is N.N.0.devN
, where N.N
are the next major
/minor
branch that will be created
and N is the next sequential number starting from 0
. For instance: "the 1.1.0.dev0
dev
release".
Note the dot before the dev0
. See https://www.python.org/dev/peps/pep-0440/#public-version-identifiers.
Examples
-
Leading up to the release of
2.0.0
the release manager would create astable
branch with the literal name "2.0.x
". They would cut release candidates named2.0.0rc0
(and so on), and afterwards, they'd finalize the2.0.0
release in that2.0.x
branch by tagging the commit with the release version:v2.0.0
. Note the lack of a dot before therc0
. See https://www.python.org/dev/peps/pep-0440/#public-version-identifiers. -
If a release manager had a bugfix from master that they needed to backport to the
1.1.x
stable
branch, they would cherry-pick the commit to the1.1.x
branch, run a series of release candidates (ie,1.1.1rc0
, etc), and finally tag the validated commit with a new patch version (iev1.1.1
). -
If
dev
releases were required after having created the1.0.x
branch, but before having created the1.1.x
branch, then they would start with1.1.0.dev0
, and continue weekly to1.1.0.devN
until the1.1.x
branch had been created.
stable
Release Candidates
In order to make a stable
release, the release manager needs to create a release candidate for
contributors to test. Once a release candidate has been created and announced according to the
Release Process, the release manager should allow five business days
for contributors to raise concerns on the release candidate announcement thread. During those five
days the release manager might need to perform multiple release candidates, until finally, when no
more blockers are raised against a particular release candidate, the final version of that release
can be cut.

Vodafone to refund 72,774 customers after ruling
Mobile phone operator Vodafone has been reprimanded by the communications watchdog ComReg for failing to tell customers they would lose out on offers by topping up early.
The company has been ordered to refund €416,971.79 to 72,774 customers.
ComReg said Vodafone had failed to comply with customer information requirements over an 18-month period from September 2016 to March 2018.
The issue related to the operator’s ‘Extra’ pay-as-you-go offers. ComReg determined that customers who topped up by €20 or €30 within 28 days of their last top-up were unaware that doing so would start a new offer cycle. This meant they lost out on any outstanding allowances as these were not carried forward after topping up.
The investigation related to the manner in which customers were advised about the offer resetting.
Vodafone accepted the findings and agreed to refund the customers and clarify its information practices.
A spokesperson said: “Vodafone worked closely with ComReg on this matter. It specifically related to whether it was clear to customers that if they chose to top up before the 28-day cycle ended, their allowances would be reset and start a new offer cycle. Following discussions with ComReg, Vodafone revised certain offer communications and have agreed to apply credits to those customers impacted.”
It is not the first time Vodafone has been ordered to refund pay-as-you-go customers. In 2017, ComReg ordered the company to issue more than €2.5m in refunds to pay-as-you-go customers who were automatically signed up to a roaming offer which saw their accounts charged €3 per day to use their existing packages within the EU.


The Mansion House was built in 1908 to serve as the official summer residence of U.S. Governors-General at the insistence of Governor-General William Cameron Forbes. The name is derived from the summer cottage in New England of Governor Forbes whose administration the original Mansion House was built under. Architect William E. Parsons, based on preliminary plans by architect Daniel H. Burnham,[2] the planner of the city of Baguio, designed the mountain retreat following the tenets of the City Beautiful Movement.[3] In 1910, the meeting of the Second Philippine Legislature was held at the Mansion House for three weeks. With the inauguration of the Philippine Commonwealth, the Mansion along with Malacañan Palace was turned over to the Philippine president. The High Commissioner to the Philippines, the successor to the Governor-General as the highest American official in the Philippines and representative of the United States Government, then built The American Residence, completed in 1940. The house was badly damaged during the Second World War and was rebuilt in 1947. Since then, it has served as the holiday home and working office for each President of the Philippines during his or her visits to Baguio.[3] The Mansion House was also used as the venue of important events, such as the second session of the United Nations Economic Commission for Asia and the Far East (ECAFE) in 1947, the second session of the Food and Agriculture Organization in 1948, and the first meeting of the Southeast Asian Union (SEAU), more commonly known as the Baguio Conference of 1950, which was conceived and convened by President Elpidio Quirino.[3] More recently, the Mansion House has been the site of a number of international conferences.
The Mansion House consists of an elegantly designed Spanish Colonial Revival main building and a guest house. The elaborate main gate, made of ornate ironwork, was earlier reported as a replica of one of the main gates at Buckingham Palace in London, which is false.[4][5][6][7][8] The front gate is still one of the most photographed section of the property. Tourists can visit the Mansion House's museum containing presidential memorabilia. Across the road from the Mansion House is Wright Park, a quiet promenade with a long reflecting pool lined with pine trees.[9] A long stairway lead visitors to the back where ponies for children are available for hire.[10] Dotted all around the nearby hills are vacation homes and small inns.


EditorIn this pane you can change the default settings used for new windows. You can choose a font and its size, change the width of a tabstop, and whether or not to show tabstops and to use syntax colouring. Show TabstopsIf this checkbox is checked, every new document will display the tabstops in the toolbar. Spaces per TabIn this edit box you can enter the amount of spaces a tab is wide. Syntax ColouringIf this checkbox is checked, Pe will use syntax colouring. The syntax colouring used depends on the language and is determined by the file extension. Auto IndentAuto Indent, when checked, will automatically enter the same amount of white space (tabs or characters) on the next line as there is on the current one when you press enter. Especially useful for programmers; not something you want if you just type normal text. Balance While TypingBalance while typing flashes the corresponding opening (curly)bracket/ parenthesis when you type a closing one. This is for programmers, so that they can check whether they closed all their opening parenthesis e.g. Smart BracesIn the C programming language a curly bracket flags the beginning and ending of program blocks. Most programmers indent the code directly following an opening curly bracket and outdent after a closing one. When you've checked this checkbox, Pe will automatically indent code after an opening curly bracket and when you type a closing curly bracket, it will be outdented to the same width as the corresponding opening curly bracket. Block CursorTo have a block cursor instead of the default vertical bar, check this checkbox. Flashing CursorIf you don't like flashing cursors, uncheck this checkbox. Smart WorkspacesWhen you choose an already open window from the Window menu, and if that window is opened in another workspace, Pe will pull that window to the current workspace before activating it-if this checkbox is checked of course. Alternate HomeWhen you are working with code, most of the lines are indented. If you press the Home key (or the equivalent you've assigned to this action) the cursor is placed at the beginning of the line. If you check this checkbox, the cursor is first placed at the beginning of the text of the current line. If you press Home again, the caret will jump to the absolute beginning of the line. Font and SizeHere you can choose the font and size to use for new documents. |

Only When I Laugh (1981)
Grade: 48
Stage actress Marsha Mason is checking out of an alcohol rehab center, where she has spent the last three months. She is given a ride back to her New York City home by Toby (Joan Hackett), her best friend. Toby is a fading beauty who is obsessed with her appearance in an attempt to retain her looks and marriage. Jimmy (James Coco), her other best friend, is stocking the fridge and preparing the homecoming.  This being a Neil Simon play, there is lots of dialogue, which is supposed to be funny and heart-warming but mostly fails to be either.
Later, Mason meets her teenage daughter Kristy McNichol, who wants to move in and re-establish their relationship. Mason also meets her most recent ex-husband, who has written a play based upon their failed marriage, and wants her to play the lead. After first saying no to both McNichol and her ex, McNichol moves in, and Mason does the play. No one asks the question, who would want to see a play based upon a couple painfully arguing for two hours. I'd rather visit my dentist.
Mason develops an interest in her ex, buying him a present. But he brings his special other to "meet" her. She learns that Toby's husband has left her and filed a divorce. And Jimmy has been fired from his play. Mason uses all this bad news as an excuse to drink again, getting plastered, causing a scene. There is much dialogue and hand-wringing. Mason goes to bar late at night, hits on a guy there, who then follows her after she leaves, confronts her on the streets, and assaults her when she is less than friendly, giving her bruises and a black eye.
The next day, Mason must apologize and explain to her daughter, who decides to move out. We are supposed to cry. Mason wants to cop out of a lunch date, with McNichol and her father, who is another ex of Mason's. She says no, but shows up anyway, wearing sunglasses to cover her bruised eyes. We are supposed to stand up and applaud her courage.
Coco, Hackett, Mason, and McNichol were all nominated for Academy or Golden Globe awards. I am surprised that such an average film received so much attention.

Gaussian unit is very useful in electrodynamics. Back to two equations used in SI unit system to define some standard units,
where we have the two constants defined as and .
The idea of Gaussian unit is as simple as setting and . The consequences are, however,
These two equalities are the most useful ones to help us switch between SI and Gaussian.
A lot of vector analysis equations will be deployed in this subject. The way to quickly prove a vector or tensor relation is to write down the component form, mess with the orders and use some specific relations.
One of the most useful symbol involved is Levi Civita symbol, which has a relation with the Kronecker delta,
As an example, we consider the case , the determinant reduces to
This relation is useful in many situations.
Gaussian integral is
To calculate higher orders we can use parity and derivitives.

For those we can use this derivative trick,
There are many ways to understand the pressure produced by light. In classical electrodynamics, we have the momentum current density, electromagnetic stress tensor, surface current density and quantum as the tools.
These are three different levels of the phenomenon.
Momentum current density is
Pressure is force per unit area or momentum change per unit time per unit area. Momentum change, meanwhile, is momentum current density times volume.
To carry out in the language of math, the volume in time and on area is given by , where c is the speed of light. Here we used c because we are basically considering the process in vacuum.
Pressure is given by
The next step is to plug in the momentu current density and calculate the difference. Here we calculate an example.
Suppose we have our incident wave normal to the surface of perfect reflection. The wave has
Finally the radiation pressure becomes
On the surface of metal, electromagnetic waves could induce surface current which in return interacts with the magnetic component in the electromagnetic wave thus producing radiation pressure.
Surface current induced is calculated using
in which since it is the magnetic field inside the good conductor.
The force is given by
The average of magnetic field is the key point here. The reason behind this 1/2 factor is that infact only half of the magnetic field outside of the conductor is the original part while the other half is induced by the surface current density however the includes all the magnetic field outside.
The pressure is
Due to conservation law, we have
which says the energy stress tensor integrated over a close surface on the interface of metal is the change in the momentum of mechanical part and electromagnetic part in total.
By using the monochromatic wave expression we can find the pressure.

The system() function executes a command supplied as an expression.[3] It does not, however, make the output of the command available within the program for processing. It returns the exit status of the command that was executed. The script waits for the command to finish before continuing execution. The following example executes the mkdir command:
[3] The system() function is modeled after the standard C library function of the same name.
BEGIN { if (system("mkdir dale") != 0) print "Command Failed" }
The system() function is called from an if statement that tests for a non-zero exit status. Running the program twice produces one success and one failure:
$awk -f system.awk
$ls dale
$awk -f system.awk
mkdir: dale: File exists Command Failed
The first run creates the new directory and system() returns an exit status of 0 (success). The second time the command is executed, the directory already exists, so mkdir fails and produces an error message. The "Command Failed" message is produced by awk.
The Berkeley UNIX command set has a small but useful command for troff users named soelim, named because it "eliminates" ".so" lines from a troff input file. (.so is a request to include or "source" the contents of the named file.) If you have an older System V system that does not have soelim, you can use the following awk script to create it:
/^\.so/ { gsub(/"/, "", $2) system("cat " $2) next } { print }
This script looks for ".so" at the beginning of a line, removes any quotation marks, and then uses system() to execute the cat command and output the contents of the file. This output merges with the rest of the lines in the file, which are simply printed to standard output, as in the following example.
$cat soelim.test
This is a test .so test1 This is a test .so test2 This is a test. $awk -f soelim.awk soelim.test
This is a test first:second one:two This is a test three:four five:six This is a test.
We don't explicitly test the exit status of the command. Thus, if the file does not exist, the error messages merge with the output:
$awk -f soelim.awk soelim.test
This is a test first:second one:two This is a test cat: cannot open test2 This is a test.
We might want to test the return value of the system() function and generate an error message for the user. This program is also very simplistic: it does not handle instances of ".so" nested in the included file. Think about how you might implement a version of this program that did handle nested ".so" requests.
This example is a function prompting you to enter a filename. It uses the system() function to execute the test command to verify the file exists and is readable:
# getFilename function -- prompts user for filename, # verifies that file exists and returns absolute pathname. function getFilename( file) { while (! file) { printf "Enter a filename: " getline < "-" # get response file = $0 # check that file exists and is readable # test returns 1 if file does not exist. if (system("test -r " file)) { print file " not found" file = "" } } if (file !~ /^\//) { "pwd" | getline # get current directory close("pwd") file = $0 "/" file } return file }
This function returns the absolute pathname of the file specified by the user. It places the prompting and verification sequence inside a while loop in order to allow the user to make a different entry if the previous one is invalid.
The test -r command returns 0 if the file exists and is readable, and 1 if not. Once it is determined that the filename is valid, then we test the filename to see if it begins with a "/", which would indicate that the user supplied an absolute pathname. If that test fails, we use the getline function to get the output of the pwd command and prepend it to the filename. (Admittedly, the script makes no attempt to deal with "./" or "../" entries, although tests can be easily devised to match them.) Note the two uses of the getline function: the first gets the user's response and the second executes the pwd command.


Hi,
first of all: thanks to the creators of this wonderful project and to the great community around it.
I'm running a couple of EmonTx v3 with the 3 Phase sketch (emonTxV3_3Phase_Voltage.ino). As a base station I use the Raspberry Pi (low write image) and additionally I'm sending the data to emoncms.org.
My question is: how could I estimate daily energy costs taking into account some conditions:
- energy costs depend on things like day/night time, weekday (and so on)
My approach would be:
- create a dedicated Wh Accumulator feed (containing the actual/approx. power usage sum of all 3 phases)
- on a daily base get the accumulator feed value (through the API) for example at 10pm and subtract the feed value at 8am.
This should give me the amount of consumed energy during that time frame (8am - 10pm). Am I right?
What would your solution look like?
Thank you in advance
Mik
Re: Estimate daily energy costs taking into account given conditions
Wh accumulator is specifically for use with wh counting on board a emonTx and requires a ever increasing total to function.
If you are only transmitting power and totalling within emoncms a normal power to kwh will do the trick.
I am tracking costs across a multi rate tarriff (Economy 7) using cron to switch tariffs at the respective times.
ie when peak kicks in the "current rate = £hi" and "peak = 1" offpeak=0"
and when off peak kicks in "current rate = £lo" and "peak =0" offpeak = 1"
processing for "peak tarriff" is Kwh's x peak (1 or 0) for peak kwhs and x currentrate for cost
similarly for "offpeak tarriff" Kwh's x offpeak (1 or 0) for off peak kwhs and x currentrate for cost
I have found this very accurate except for the fact I have a PV diverter and if that is working well then the to and fro'ing within the "sweet zone" or "energy bucket" adds to the recorded energy totals in both directions but that has nothing to do with the tarriff split as they always match the total when summed.
The script I use with cron and emonhub is available on github and called cronnode
There is also a "EmonCMS multi rate scheduler" in development which looks more powerful but won't be able to be used with emoncms.org as it's a separate module.

Re: Estimate daily energy costs taking into account given conditions
Thank you Paul for sharing your approach.
I sure got that accumulator thing totally wrong :) If would have been really nice if that was the case (accumulate the kWh and query the value for a given time). I'm wondering how I could achieve that. It would be great to get only the data (kWh) for the various time frames I'm interested in and do the math outside of emoncms.
I would need that, because on my bill I have different prices for the first X kWh per month, a price for the next Y and after surpassing a defined threshold I will pay another price.
Mik
Re: Estimate daily energy costs taking into account given conditions
Its totally possible to track the usage in a way that's more suited to your needs for starters if you new the month to date kwh's the rest would be easy to do maually outside emoncms and could be the basis of automating the process.
If you start with the normal tracking and to that add a second power to kwh feed called something like "month2date" this would just follow the normal every increasing tally of energy used. But if you then add an input using the input api for example http://emoncms.org/input/post.json?node=1&apikey=xxxxx&json{mtd=0} and you add one process "log to feed" and select the "month2date" feed previously created. When ever that api url is used it will reset the month to date to 0.
Then set up a cron to run that url request at midnight the 1st of each month (or whenever your billing cycle starts) this will give you a actual amount used this month throughout the month. to simplify your calcs.
You could include a second value to that api url with your 1st band price per unit so that you can also calculate a rolling cost for both the month and the total kwhs.eg http://emoncms.org/input/post.json?node=1&apikey=xxxxx&json{mtd=0,ppu=25} (as in 25 PencePerUnit)
To that you add a simple script that polls the month to date feed and if that value is greater than your 1st break point it sends http://emoncms.org/input/post.json?node=1&apikey=xxxxx&json{ppu=15} (2nd band price) and when the returned value reaches the next break point http://emoncms.org/input/post.json?node=1&apikey=xxxxx&json{ppu=5} (3rd band price)
At which point your dash board can display not only the accurate month to date units used but accurate cost for the month too.
It sounds complex but that's probally just the long winded explanation.
Basically a cron and a send if greater than script and your there.
Paul
Re: Estimate daily energy costs taking into account given conditions
Thanks Paul, but as mentioned in the previous post there is an additional variable (the time of the day and the week day). I can't see how I can handle that in your last suggestion.
Mik
Re: Estimate daily energy costs taking into account given conditions
I'm not sure I understand your tariff but the bottom line is once you know the equation it should be achievable as cron can cope with any schedule and you can fetch the "total since whenever" from emoncms into a simple script to act on "unit counts since" the combination of the 2 can set a "tariff node" of control data prices etc that you can manipulate to effect the collected data, so the units get added to the right tarrif feeds and those feeds multiplied by price per unit give you cost to date or month to date.
If you layout the full terms of your tariff (the exact prices/times and quantities etc can be altered for privacy) I'll give it a whirl for you
Paul
Re: Estimate daily energy costs taking into account given conditions
Hi Paul, I've looked at my bill and I've noticed that taking into account only the time/day variable should work out just fine.
Now I will try to wrap up the information you gave me. I still have a couple of questions:
- do I have to create a "Power to kWh"-feed?
- with which URL/method should I query the value for the start and end of a tariff timeframe?
Thanks
Mik
Re: Estimate daily energy costs taking into account given conditions
Hi,
I've decided to do all the math outside of Emoncms. Now I've the relevant data in multiple feeds.
Is there an API call to get the feed value on a given unixtimestamp?
I've seen the data.json call, but I wasn't able to get proper data from it.
Thanks
Mik

Programming & Web Design are things that have always been of great interest to me. This year, I have decided to pursue them as a career. I have completed a self-funded bootcamp provided by Just IT, where I have a gained a lot of skills in a short amount of time. The course covered HTML, CSS, JavaScript, C#, ASP.NET, SQL and MVC concepts.
For the past two years, I have worked as a Designer/IT Admin for S6 Design & Print. My key responsibilities included; design (obviously!), planning for commercial projects, maintainence of network and managing a wide-format print operation.
Straight from secondary school, I got a job as a graphic designer for a community magazine. During my time there, I studied design in my free time and learned on the job. I completely overhauled the layout and design of the publication and made many imporvements to the workflow that still stand today.
I attended Woodlands School, Basildon for 5 years, gaining 11 GCSEs in Maths, English, Triple Science, Geography, German, Music and IT. All A*–C grades.

In 2D there is no clear definition of this operation.
This implementation is the most common one and will return the magnitude of the vector that would result from a regular 3D cross product of the input vectors, taking their Z values implicitly as 0 (i.e. treating the 2D space as a plane in the 3D space). The 3D cross product will be perpendicular to that plane, and thus have 0 X & Y components (thus the scalar returned is the Z value of the 3D cross product vector).
this.x * other.y - this.y * other.x
Other implementations take no arguments and returns a vector perpendicular to the input vector. This can be reached with the toOrthogonalVector() method, which returns a perpendicular copy of the vector.


module ActiveRecord::Tasks::DatabaseTasks
ActiveRecord::Tasks::DatabaseTasks
is a utility class, which
encapsulates logic behind common tasks used to manage database and
migrations.
The tasks defined here are used with Rake tasks provided by Active Record.
In order to use DatabaseTasks, a few config values need to be set. All the needed config values are set by Rails already, so it's necessary to do it only if you want to change the defaults or when you want to use Active Record outside of Rails (in such case after configuring the database tasks, you can also use the rake tasks defined in Active Record).
The possible config values are:
* +env+: current environment (like Rails.env). * +database_configuration+: configuration of your databases (as in +config/database.yml+). * +db_dir+: your +db+ directory. * +fixtures_path+: a path to fixtures directory. * +migrations_paths+: a list of paths to directories with migrations. * +seed_loader+: an object which will load seeds, it needs to respond to the +load_seed+ method. * +root+: a path to the root of the application.
Example usage of DatabaseTasks
outside Rails could look as
such:
include ActiveRecord::Tasks DatabaseTasks.database_configuration = YAML.load_file('my_database_config.yml') DatabaseTasks.db_dir = 'db' # other settings... DatabaseTasks.create_current('production')

This method is used for tokenizer queries.
The reason I created an extra method, that does the exact same thing as the previous tokenizer method, is for the small performance gain doing spell correction inside this method gives me. Previously we called a separate method that took the completely tokenized list and then did spell correction on each term.. This is not very good, O(n+M)
- Note
- for doc indexing use before doc.title + " " + doc.body because of the limited size of our corpus, spelling correction results in slight boost with a larger corpus you would not do this, especially due to the simplicity of the spelling correction

g2 comes with another custom HTML element. This element aims to allow the rendering of charts without the necessity of scripts and to minimize the implementation overhead for the user. while maintaining the flexibility g2 provides.
To implement the g2 element into your page just import the g2.chart.element.js
.
The <g2-chart>
follows the same syntax as the regular g2.chart
element, but some things have to be considered.
For the g2.chart
element refer to its documentation here.
The funcs
array is given as innerHTML that is the text between the <g2-chart>
tags.
All other properties are given as parameters into the opening tag:
width
: Width of the element inpx
.height
: Height of the element inpx
.xmin
: The lowest number on the x-axis.ymin
: The lowest number on the y-axis.xmax
: The highest number on the x-axis.ymax
: The highest number on the y-axis.title
: The title of the graph.
Examples #
<g2-chart width="301" height="150" ymin=-3 title="Test">
[{ "data": [-2,6,0,-2,2,1,4,1,6,5], "fill":true, "dots":true }]
</g2-chart>
Functions to draw graphs are supported, but the usage of outside variables is not. However, the chart can be updated from the outside; see the third example.
<g2-chart width="300" height="150" xmin=-1.8 xmax=6.28 ymin=-3 ymax=3 title="Test">
[
{"fn":Math.sin,"dx":0.104,"fill":true},
{"fn":Math.tan,"dx":0.0349,"fill":true}
]
</g2-chart>
The g2-chart
HTML element can also be used to be referenced by another instance of g2.
The funcs
object can be updated accordingly using the setFuncs
function.
<g2-chart id="chart"></g2-chart>
<script>
const chart = document.getElementById('chart');
const funcs = [{"data": [-2,6,0,-2,2,1,4,1,6,5], "fill":true, "dots":true}]
chart.setFuncs(funcs).render();
</script>
Note: Don't forget to use quotations (e.g.
"data"
) for the properties, since theg2-chart
interprets theinnerHTML
using the JSON format.

Hi All
I'm looking for a way to calibrate my meter's CTs. I need to pass through a constant known current of 10A in order to read their values and record this.
How can I do this without getting one of those expensive machines.

Re: Calibration techniques
Which meter and which CTs?
You can look at the report on the YHDC ct in Building Blocks - that tells how I tested the CT up to 250 A using an ordinary moving iron 5 A meter. OK, I didn't have to buy the variac or the transformer - I had those already - and you don't either: if you have a multimeter that can read alternating current, you select a load whose running current is close to but less than that maximum, and use that. If you don't have or cannot borrow a suitable multimeter, you will have to rely on the tolerances of the CT and the various other factors that influence calibration, and then over time adjust the calibration by small amounts until it agrees with your energy supplier's kWh meter.
Re: Calibration techniques
A couple of years back, I posted a Digital Meter Emulator sketch which runs on an emonTx V2 or similar platform. This sketch generates a visible pulse whenever 1 Wh of energy has been recorded by its CT.
Calibration is adjusted by altering the value of powerCal. When the CT is clipped next to the supply meter, and both visible indicators are pulsing at the same rate, the calibration is correct.
This same powerCal value can be used with any of the sketches that I've posted. Recorded values of power/energy should therefore be fairly accurate.
According to my Summary Page:
DigitalMeterEmulator. This sketch uses V and I sensors to determine real power, with the on-board LED being set to behave just as the LED on a digital supply meter. Originally posted on 26/10/12 at http://openenergymonitor.org/emon/node/857#comment-6867, this tool is available at

If you switch on a kettle or similar, the supply meter will pulse at a fairly quick rate. If you count the rate of these pulses, that will tell you how much power is flowing. If your meter's CT is clipped next to the supply meter, then the same amount of power will be flowing through both of them. The current won't be exactly 10 Amps, but it will be known reasonably accurately by counting the pulse rate.
Re: Calibration techniques
Thanks for the response.
How stable is the current using the variac / transformer method. Surely the heating of the load affects it?
In the report's test rig picture, whats the function of both resistors. I'm assuming one of them is a variable resistor which is used to alter the current magnitude.
Secondly why do you go through a secondary transformer, why not just go from the autotransformer directly to the circuit?
Re: Calibration techniques
One resistor is to sense the current, (for feeding into an oscilloscope etc), the other is the load. Both are shown as fixed resistors, which they are. What's the point of having a variable resistor in there? - there's absolutely no need. The step-down transformer makes it quite safe to work on live as it's only 6.5 V maximum, therefore the power requirements are minimal and although the heat sink that the load is on gets quite warm, the dissipation is only in the tens of watts range. The current is stable enough to take readings - provided you don't try to do it when the mains voltage is bouncing around too much. Because the dissipation in the resistors is kept down, self heating isn't a major problem.
Re: Calibration techniques
Ok got it, thanks. Didnt quite look properly at the 0.33 resistor.
Still though, why not just down bring the voltage to 6.5 with the variac. Why are you going through an additional transformer?
With a single variac and perhaps a variable resistor you would be able to get a custom current while minimizing power loss.
I suppose I could use this method with a 7.2V and 0.72 ohm load. But 72W power dissipation in the resistor, is this really negligible?
Re: Calibration techniques
"Still though, why not just down bring the voltage to 6.5 with the variac." You need to take a step back and think the problem through in total. Two questions for you: How do you accurately adjust the voltage, and is the low voltage side then isolated from the mains?
I never said the dissipation in the resistor is negligible - if it can get a large multi-finned heat sink warm it clearly is not negligible.
Re: Calibration techniques
"How do you accurately adjust the voltage, and is the low voltage side then isolated from the mains"
I'm not too sure on your questions. Surely adjusting the variac until you reach your desired voltage (measured) is enough. Accuracy as measured by the voltmeter.
As far as isolation is concerned, the variac is still a transformer, we only changing the secondary coil.
I'm just trying to find out the purpose of the second transformer.
If I create a setup such as yours - besides for cost implications - do I need that transformer


My name is James Henager and I am a software developer from Phoenix, Arizona. Currently I live in Portland, Oregon where I am pursuing a certificate in web and mobile development at Epicodus.
I gained my first project management experience as the Event Coordinator for the Student Government at Portland Community College: Cascade. This experience opened new doors for me in the restaurant industry, where I first began as a dishwasher in 2013. In 2019 I was hired at busy downtown Portland restaurant LeChon, as the Private Event Coordinator. Many of my clients in the tech industry encouraged me to learn how to code, which is how I came to enroll at Epicodus!
I have had a great fondness for technology ever since I received my first Gameboy as a kid. Videogames are a love of mine, and I enjoy collecting both retro and modern games. Seeing live music is another of my favorite activities! Japan has always greatly interested me as well, and I was fortunate enough to finally visit in 2019!

Went to court today to witness against the scumbag who vandalised my car - the
incident that started my interest in local antisocial behaviour. This is how it
went…Got to court about 9am and had to wait 1o minutes or so to get in. Just
the right amount of time to get cold and reflect on the court-case and start
worrying. Finally, got in and entered the witness room. I understood that the
defendant would be in at 10 and at this time I was disappointed by the non show
up of my neighbours - better witnesses than me having seen the whole incident
and knowing the defendant. In my mind, only the presence and willingness to
testify of all witnesses would cause the defendant to plead guilty therefore
removing my need to appear in court.
I was relieved when a couple of minutes later, my neighbours did show up. They
had seen the defendant downstairs, this pleased me as no shows from defendants
is supposedly quite common and would mean another day in court. We were then
introduced to both the prosecutor and investigating P.C. The prosecutor
impressed me with his informal way with us non legal types. He explained clearly
what would happen and most interestingly for me, how the cross questioning from
defence would work. This worried me as he would easily establish that I couldn’t
recognize the defendant from my brief view of his face.
Anyway, the intercom called for the defendant and defense / prosecuting
solicitors ( or lawyers, I don’t really know the difference) ; it was about to
begin. About 30 minutes passed with only a bit of conversation and police banter
taking my mind from my impending call to stand. Then the prosecutor returned
informing my neighbours and me that we were free to leave - the defendant had
done what I had hoped for days, he had pleaded guilty. Many do at the last
minute when they realise a full hand of prosecutor witnesses have turned up.
So there you go, my first day in court and no court case. Just got to wait a
couple of weeks now for the sentence to be announced - just about enough time
for corporal punishment to be reintroduced for antisocial behaviour offences.
Here’s hoping….
