RE: TPad::Range(), and pointing down y axes.

Hi,
For the time being this is not possible in a simple way. It is on the program of work.
The only trick you can do now is the one suggested here: http://couet.home.cern.ch/couet/root/ht16.html Cheers,

Subject: [ROOT] TPad::Range(), and pointing down y axes.

Hi all!
TPad::Range(...) protests when I try an give it: ((x1 >= x2) || (y1 >=
y2)), i.e., for example, the vertical axis cannot point downwards.
Now, when I Draw() my TPolyLines, I wish to have my axes origin at the
top-left corner, and the y axis must point downwards: How can I do it?
This one must be simple, but I really can't figure it out... Am I
missing something about coordinate systems?
Thanks
Ciao!
Giorgio
