Unsolved How to control 2D slice view of Q3DSurface?

[Diracsbracket]

Hi,
How can I select which row/column slice is shown in the 2D slice view of my surface? Currently, I get the 2D slice view by clicking on the surface, but I would like to set it programatically, e.g. using a QSlider to select the slice.

Also, how can I get access the properties of the 2D slice graph itself? For example, its size is too small, and I would like to make it larger. Also, the xAxis labels of the 2D view are rotated by a small amount, which I would like to disable.

Thanks for your help!
