When I draw a TH2F using the “cont4z” option and then draw a TMarker object on the same pad, the position that I use to construct the marker is different than the one displayed. If instead I draw the TH2F with the “colz” option and then the TMarker, the position is correct.
Is there a change in the coordinate system the marker uses when the “cont4z” option is used?
I am using 5.28-00c on a linux rhel5-32 machine, but the behavior is the same using 5.26-00 on a SL4-32 machine. I have attached a macro that reproduces this issue on my machine which I compile with aclic. Is this the expected behavior?
