Well, managed to get a 2-D histogram filled from a tree and plotted with
contours, surfaces, etc. Now all I want to do is set my own contour
levels.
I've done eg:
Float_t lev1[2]={0.39,0.45};
h1.SetContour(2,lev1);
Float_t lev2[3];
h1.GetContour(lev2);
printf("%f %f",lev2[0],lev2[1])
All well and good so far, but if I do:
h1.Draw("surf");
I get the specified number of contours, but the contours are equidistant.
What am I doing wrong?
Thanks,
Chris.
