Hi, I’ve set up a TGraph2D and I wonder why there is a gap in the surface. Is this because of my data? And/or how can I avoid/close that? And is there a possibility to set a title for axis? Thank you! [dM vs Ubr vs SN]

It looks like your data gets out of the range of the TGrahp2D. In that case that is no gap but a cut off. To solve just increase the range of your left axix perhaps to 3000 and look if there is really a gap or if its just a cut off.

[image] Progressive: And is there a possibility to set a title for axis? Use TAxis::SetTitle: graph->GetXaxis()->SetTitle("x-axis"); graph->GetYaxis()->SetTitle("y-axis"); graph->GetZaxis()->SetTitle("z-axis");
