How to get rid of the white space to the right of the chart?

I have a chart with a lot of white space to the right of it, and I can’t resize the chart area. If I try to resize it with the handles, the chart itself is squeezed, so that the same proportion of white space remains. There once was a legend that I deleted afterwards.

Hello,

you need to resize the Chart Wall inside the chart and not the chart object itself

Hope that helps.
