Contributing

New contributions to the library are welcome, but we ask that you please follow these guidelines:

• Use tabs for indentation, not spaces.
• Only change the individual files in /src.
• Check that your code will pass eslint code standards, gulp lint will run this for you.
• Check that your code will pass tests, gulp test will run tests for you.
• Keep pull requests concise, and document new functionality in the relevant .md file.
• Consider whether your changes are useful for all users, or if creating a Chart.js plugin would be more appropriate.
