You update the Data of your chart and retrieve the chartArea. The chartArea has not the correct dimensions, because the items on the x Axis hava a rotation after the update.

Possible solution

Do you use the label rotations for the calculation? It does not seem that way.

Context

I need the correct chartArea because i have two separate charts. One as a draggable overlay. I want to create one combined canvas image. So i need the exact chartArea of the chart below the overlay.

As described in the issue template:

Chart.js versions lower then 4.x are NOT supported anymore, new issues will be disregarded.

Also a reproducible sample is mandatory, please add one

I updated my chart lib to the latest version. The problem is still there. Label rotation is not considered when calculating the chartArea. Just compare the values of the chartArea before and after an update that adds enough labels so that they need to be rotated to fit. Nothing changed to previous versions in that regard.
I'll try fixing it locally if i have the time.
