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 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 in the documentation, and some of the community extensions that have been created already.

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 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 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.

Pull requests

Clear, concise pull requests are excellent at continuing the project's community driven growth. But please review these guidelines and the guidelines below before starting work on the project.

Guidlines:

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, 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
Please make your commits in logical sections with clear commit messages
