Set z-axis range of TGraph2DErrors automatically from errors

Just a quick question - I’m plotting a TGraph2DErrors over another TGraph2D so I can see both the surface and the error bars through the points. Is there any way of setting the range of the z-axis automatically using the errors rather than just the points, or can I only make the full extent of the error bars visible manually?

Apologies if this is documented anywhere but I have been unable to find an answer if so.

Many thanks

Do you have a small reproducer ?
