4.x Migration Guide

Chart.js 4.0 introduces a number of breaking changes. We tried keeping the amount of breaking changes to a minimum. For some features and bug fixes it was necessary to break backwars compatibility, but we aimed to do so only when worth the benefit.

End user migration

Charts

  • Charts don't override the default tooltip callbacks, so all chart types have the same-looking tooltips.

Options

A number of changes were made to the configuration options passed to the Chart constructor. Those changes are documented below.

Specific changes

  • The radialLinear grid indexable and scriptable options don't decrease the index of the specified grid line anymore.
  • The destroy plugin hook has been removed and replaced with afterDestroy.
  • Ticks callback on time scale now receives timestamp instead of a formatted label.
  • Linear scales now add and subtracts 5% of the max value to the range if the min and max are the same instead of 1.
  • If the tooltip callback returns undefined, then the default callback will be used.

Type changes

  • The order of the ChartMeta parameters have been changed from <Element, DatasetElement, Type> to <Type, Element, DatasetElement>.

General

  • Removed fallback to fontColor for the legend text and strikethrough color.
