I am trying to create a TH2F and fill it, I want the pixel colors to be red so I use SetFillColor, but my pixels are still turning out black. Can you please have a look at the attached files and suggest the correction. Everything is fine except I want my pixels to be red instead of black.
Note also:
To learn about the set-functions you need to use to change attributes, the simplest way is to modify the picture interactively and to save it in a .C file. In this .C file you will find the function calls needed to perform the changes you just did.
