When I try to draw a profile histogram that I've filled using
TChain::Project I get the message
Warning in <TCanvas::ResizePad>: c1 height changed from 0 to 10
and nothing appears to draw, other than the blanking of the very top of
the window. This was working fine, and without making any significant
changes to my scripts this problem appeared all of a sudden. If I just
fill the histogram with a few events this problem does not occur.
There was a thread about this about two months ago ("Problem drawing
functions"), but it's not clear what the fix or workaround was, or even
where the problem came from. Any ideas?
Cheers,
