Pie Chart use legend space for graph

Hello,

BO 4.1 SP 3.

I've tried to use maximum space inside the "Pie Chart" frame I have in a report, but couldn't make the graph itself bigger from the default - without enlarging the height\weight of the entire frame.

As you can see in the pic, There's the "external" frame, and the "internal" frame that shows the chart itself. I disabled legend, so there's no possible reason for not being able to maximizing the space for the graph itself - So, Is it possible?

Thank you,

Or.
