Chart.js v2.7.0 Release Notes

Release Date: 2017-09-10 // over 6 years ago

  • Version 2.7 brings better stability, and powerful new features to Chart.js. The bubble chart options are now completely scriptable. This means that you can pass a function to a bubble chart dataset property and have the function be called as needed. This simplifies array properties, and allows quick and easy rendering changes based on data values. Check out the sample for details. If these options prove useful, they can be extended to other chart types in the future.

    🏗 Building off the time scale rewrite in version 2.6, the time scale now supports options for configuring how labels generate ticks, how interpolation between the points is handled and the scale boundary strategy. Users can now configure ticks to be generated for each label, or be determined automatically from the data limits. Users can also change how ticks are distributed along the axis] to make non-linear time axes. Check out the sample for details.
