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.
scales[id].grid.drawBorder has been renamed to scales[id].border.display.
scales[id].grid.borderWidth has been renamed to scales[id].border.width.
scales[id].grid.borderColor has been renamed to scales[id].border.color.
scales[id].grid.borderDash has been renamed to scales[id].border.dash.
scales[id].grid.borderDashOffset has been renamed to scales[id].border.dashOffset.
The z index for the border of a scale is now configurable instead of being 1 higher as the grid z index.
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.
