Surface chart grows in size when starting to rotate

Post by hcknobel » Thu Nov 30, 2023 4:09 pm

I have a VCLTee.TeeSurfa 3D surface chart using the Athens version of Delphi and the latest teeChart version. I define my chart to be about half the size of the containing panel, and with the Rotate tool. When I first display the chart at runtime, it is the designed size. However, as soon as I start dragging it to rotate it, it jumps to about a 50% larger size in all 3 dimensions. How do I prevent this resizing?

Hello,

The TRotationTool modifies the Rotation and the Elevation properties, but to do so, it also sets Orthogonal property to False.

Sometimes, setting your starting view with Orthogonal:=False avoids that jump when using the TRotationTool.

If you still find problems with it, please arrange a simple example project we can run as-is to reproduce the problem here.
