Chart.js v2.6.0 Release Notes

Release Date: 2017-05-25 // almost 7 years ago

  • Version 2.6 brings better stability, improved documentation, and powerful new features to Chart.js. It's now possible to create advanced area chart thanks to a new filler plugin: stacked area charts can now fill to another dataset in a configurable manner. Check out the samples to see the all the new options.

    🐎 The time scale internals have been rewritten, improving performance by reducing the number of operations on each tick value. These changes also fixed a number of time scale related issues that users have been experiencing.

    📚 Our new documentation has been rewritten using GitBook and reorganized into smaller topics to improve clarity and allow topics to be more intuitively found. The online documentation is now organized by release version going forward: http://www.chartjs.org/docs/{version}/.

    💥 Breaking Changes

    • 🚚 #3782 The lineArc setting for the radial linear scale has been removed and replaced by gridLines.circular and pointLabels.display.
