Hi,

it was discussed some time ago here :
(thanks to Henso who reads this hypernews to have found the link and explanation)

http://root.cern.ch/phpBB3//viewtopic.php?t=6947&view=next&sid=cd602857c8522df6ac8123ae9f29ebfd

to summarize, it would be due to the version of root that you use (below 5.20 in cint)

==>if you create a dummy canvas before your loop, the warning should
disappear
TCanvas *mydummycanvas=new TCanvas();

regards
