# Deprecation: #99150 - Updated chart library in EXT:dashboard

See [forge#99150](https://forge.typo3.org/issues/99150)

## Description

The library `chart.js` used to render charts in a dashboard has been
updated to version 4.x, introducing some breaking changes. A migration layer is
in place to migrate known and used affected settings.

## Impact

The CSS file `EXT:dashboard/Resources/Public/Css/Contrib/chart.css` became
obsolete with the update of `chart.js` and was therefore removed without
replacement.

If a migration is executed, an entry will be written into the deprecation log.

## Affected installations

All plugins providing third-party chart widgets are affected.

## Migration

Migrate the configuration as mentioned in the table below.

| Old setting | New setting |
| --- | --- |
| graphConfig/options/scales/xAxes | graphConfig/options/scales/x |
| graphConfig/options/scales/yAxes | graphConfig/options/scales/y |
