Hello rooters,
I am using root 3.10.02 + GDK on Microsoft Visual C++ 6
I have a class that inherits from TH2D, when I try to draw it using
"lego" option, instead of getting full lego-bars, I got thin lego
(sometimes "lines", sometimes nothings it depends of the order of call
of the various options) (see attached c1.ps )
If I draw it using "box" option I obtain and empty histogram display.
(although using the Event Status Option one can verify that bins are not
empty)
I haven't managed to find out what initialisation of histogram I am
missing to have them be drawn correctly with "box" and "lego" ,
apparently TH2D::TH2D() + TH2::TH2() + TH1():TH1() + SetBins(...) don't
make it...
