(I already sent the following message some days ago but appearently there were problems, because I have not seen it distributed on the list. In case you did, please excuse this double)

Merci Olivier!
Unluckily that code just throws away an axis and draws another, which is not what I need.
I'll contiinue and do mirror transformations myself (just 1-y, nothing too difficult :-)
It would be nice to have a method that inverts coordinate axes directions, so that - for example - plotting a dot at (0, 0) places it at the top left corner of a TPad.

Thanks again!

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,

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. ...
