I’m a newbie here, I want to draw a TF2 function with TGraph2D (or any 3D graph), is there anyway to draw directly instead of adding points to the graph like AddPoint(x, y, func->Eval(x,y))?
Thank you count, actually I read the TF2 doc. before asking the question but didn’t get the answer… can you tell me more specifically about the method or where it is written?
