Hi Selim, Your mail was already answered concerning your question; Why you get a clustered plot? Concerning the removing of the title, you have 3 possibilities: - in the canvas option menu, select the option "no histogram title" - execute gStyle->SetOptTitle(kFALSE); - htemp->SetTitle(); You were using the third option with no success. This was a problem in the way we iterate on the list of primitives in TPad::PaintModified. When the htemp object was painted, it deleted the next object (title) in the list and the iterator was confused. I have modified the iterator procedure and the problem is now fixed. Thanks for reporting this problem. Rene Brun Selim Issever wrote: > > Hi all,.. > > and some more questions/observations from me,..
