Funny ps

  1. I drew some graph in a canvas with a loop (Root 3.10/03). The size of the title in the ps output is not always the same (! The screen canvas doesn’t show this. Is there an explanation?

  2. Another problem: The marker eat the error bar in Only the biggest error appear. (37.4 KB) (12.8 KB)

The histogram title box isize is a function of the title length.
You can fix a size via gStyle->SetTitleW(xx), eg xx=0.4

It is hard to see the problem.
Could you try with a more recent version or send the canvas.root file such that we can test ourselves your picture with a more recent version.
