Dear All,
while I draw a scatter plot in a Canvas using the Contz option (contour plot) I am exactly getting the correct plots.

But while I try to save the 2D Contz plots in a root file all the colour which is supposed to present in a contour plot disappear and I got only a simple 2D scatter plot.

So, is there any trick to save the Contz plots in a root file.


I am not able to reproduce this problem. It works fine for me on Mac with the latest ROOT version.
So usual questions:

  • on which machine are you using ROOT ?
  • which ROOT version ?
  • Do you have an example reproducing the problem ?
