Contributing to Chart.js
|
||||
========================
|
||||
|
||||
Contributions to Chart.js are welcome and encouraged, but please have a look through the guidelines in this document before raising an issue, or writing code for the project.
|
||||
|
||||
|
||||
Using issues
|
||||
------------
|
||||
|
||||
The [issue tracker](https://github.com/chartjs/Chart.js/issues) is the preferred channel for reporting bugs, requesting new features and submitting pull requests.
|
||||
|
||||
If you're suggesting a new chart type, please take a look at [writing new chart types](https://github.com/chartjs/Chart.js/blob/master/docs/07-Advanced.md#writing-new-chart-types) in the documentation or consider [creating a plugin](https://github.com/chartjs/Chart.js/blob/master/docs/07-Advanced.md#creating-plugins).
|
||||
|
||||
To keep the library lightweight for everyone, it's unlikely we'll add many more chart types to the core of Chart.js, but issues are a good medium to design and spec out how new chart types could work and look.
|
||||
|
||||
Please do not use issues for support requests. For help using Chart.js, please take a look at the [`chartjs`](https://stackoverflow.com/questions/tagged/chartjs) tag on Stack Overflow.
|
||||
|
||||
|
||||
Reporting bugs
|
||||
--------------
|
||||
|
||||
Well structured, detailed bug reports are hugely valuable for the project.
|
||||
|
||||
Guidlines for reporting bugs:
|
||||
|
||||
- Check the issue search to see if it has already been reported
|
||||
- Isolate the problem to a simple test case
|
||||
- Provide a demonstration of the problem on [JS Bin](https://jsbin.com) or similar
|
||||
|
||||
Please provide any additional details associated with the bug, if it's browser or screen density specific, or only happens with a certain configuration or data.
|
||||
|
||||
|
||||
Local development
|
||||
-----------------
|
||||
|
||||
Run `npm install` to install all the libraries, then run `gulp dev --test` to build and run tests as you make changes.
|
||||
|
||||
|
||||
Pull requests
|
||||
-------------
|
||||
|
||||
Clear, concise pull requests are excellent at continuing the project's community driven growth. But please review [these guidelines](https://github.com/blog/1943-how-to-write-the-perfect-pull-request) and the guidelines below before starting work on the project.
|
||||
|
||||
Be advised that **Chart.js 1.0.2 is in feature-complete status**. Pull requests adding new features to the 1.x branch will be disregarded.
|
||||
|
||||
Guidelines:
|
||||
|
||||
- Please create an issue first:
|
||||
- For bugs, we can discuss the fixing approach
|
||||
- For enhancements, we can discuss if it is within the project scope and avoid duplicate effort
|
||||
- Please make changes to the files in [`/src`](https://github.com/chartjs/Chart.js/tree/master/src), not `Chart.js` or `Chart.min.js` in the repo root directory, this avoids merge conflicts
|
||||
- Tabs for indentation, not spaces please
|
||||
- If adding new functionality, please also update the relevant `.md` file in [`/docs`](https://github.com/chartjs/Chart.js/tree/master/docs)
|
||||
- Please make your commits in logical sections with clear commit messages
|
||||
|
||||
Joining the project
|
||||
-------------
|
||||
- Active committers and contributors are invited to introduce yourself and request commit access to this project. Please send an email to hello@nickdownie.com or file an issue.
|
||||
- We have a very active Slack community that you can join at https://chartjs-slack-automation.herokuapp.com. If you think you can help, we'd love to have you!

# chartjs-plugin-zoom
|
||||
|
||||
A zoom and pan plugin for Chart.js >= 2.1.0
|
||||
|
||||
Panning can be done via the mouse or with a finger.
|
||||
Zooming is done via the mouse wheel or via a pinch gesture. [Hammer JS](https://hammerjs.github.io/) is used for gesture recognition.
|
||||
|
||||
[Live Codepen Demo](https://codepen.io/pen/PGabEK)
|
||||
|
||||
## Configuration
|
||||
|
||||
To configure the zoom and pan plugin, you can simply add new config options to your chart config.
|
||||
|
||||
```javascript
|
||||
{
|
||||
// Container for pan options
|
||||
pan: {
|
||||
// Boolean to enable panning
|
||||
enabled: true,
|
||||
|
||||
// Panning directions. Remove the appropriate direction to disable
|
||||
// Eg. 'y' would only allow panning in the y direction
|
||||
mode: 'xy'
|
||||
},
|
||||
|
||||
// Container for zoom options
|
||||
zoom: {
|
||||
// Boolean to enable zooming
|
||||
enabled: true,
|
||||
|
||||
// Zooming directions. Remove the appropriate direction to disable
|
||||
// Eg. 'y' would only allow zooming in the y direction
|
||||
mode: 'xy',
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## To-do Items
|
||||
The following features still need to be done:
|
||||
* Pan limits. We should be able to set limits for all axes or for a single axis, identified by ID, that are the maximum and minimum values, in data values, that can be panned to.
|
||||
* Zoom limits. Similar to pan limits but for zooming
|
||||
* Panning of category scales (the ones that use strings as labels)
|
||||
* Zooming of category scales (the ones that use strings as labels)
|
||||
|
||||
## Installation
|
||||
|
||||
To download a zip, go to the chartjs-plugin-zoom.js on Github
|
||||
|
||||
To install via npm / bower:
|
||||
|
||||
```bash
|
||||
npm install chartjs-plugin-zoom --save
|
||||
```
|
||||
|
||||
Prior to v0.4.0, this plugin was known as 'Chart.Zoom.js'. Old versions are still available on npm under that name.
|
||||
|
||||
## Documentation
|
||||
|
||||
You can find documentation for Chart.js at [www.chartjs.org/docs](https://www.chartjs.org/docs).
|
||||
|
||||
Examples for this plugin are available in the [samples folder](samples).
|
||||
|
||||
## Contributing

||||
|
||||
Before submitting an issue or a pull request to the project, please take a moment to look over the [contributing guidelines](https://github.com/chartjs/chartjs-plugin-zoom.js/blob/master/CONTRIBUTING.md) first.
