Hi Michal,
When one projects a TTree into an histogram, the histogram inherits the Tree
attributes and not the current style attributes. This gives the possibility
to project two Trees with different attributes into the same picture.
The problem, in your case, is that TTree was not able to use the current style,
despite the call to ForceStyle because the function TTree::useCurrentStyle
was not implemented.
I have now implemented it in the dev version 2.24/06. With this version,
your macro will work as expected.
Thanks for reporting this anomaly.
