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.
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 or consider creating a plugin.
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.
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.
Run npm install
to install all the libraries, then run npm run build
to build and npm test
to run tests as you make changes.
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.
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
- If adding new functionality, please also update the relevant documentation
- Please make your commits in logical sections with clear commit messages
- Active committers and contributors are invited to introduce yourself and request commit access to this project.
- 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!
