Re: Drawing the leafs of TTrees

Hello Philippe,

Since I do not need the graphics output in a script, I use "groff" option in Draw() and gPad is not being created (gPad==NULL). So it doesn't work...

Moreover, even if I'm really drawing the plot (without "groff" option), the FindObject("Graph") for unknown reason returns NULL.
