Hello,
how do I draw 3d points with coordinate axes or a 3d graph?
I would like to do something similar to the TGraph class or the example in
zdemo.C (in the tutorials), but in 3d.
Asked in a different way: How can I get an empty 3d histogram to add my 3d
point to?
When I do
TH3F *hr=new TH3F("hr","title",2,0.0,1.0,2,0.0,10.0,2,0.0,10.0);
hr->Draw();
the canvas is created, but nothing is drawn inside it.
If I use TH2F instead, I cannot regulate zmin and zmax.
Does anybody know what to do?
Thanks,
Reinhard
