RE: how to draw (x,y.z) point without binning x and y ?

TGraph2D with option P or P0 is the answer. See TGraph2D help.

Hi-
I'm having a similar problem. I know that TMarkers can be used for a plot of non-binned datapoints in a 2D-plane --maybe this somehow helps Xianguo-- but how can we extend to three dimensions? cheers
