I have a canvas, divided in 4 pads:
TCanvas *c=new TCanvas ("c", "Phase Space Plots", 800, 850);
I would like to leave a free space in the canvas upper region , as large as two pads, in order to add a pave where writing some output of my script.
I tried to reduce pads occupancy area, by setting pads margins:
but it doesn’t produce the expected picture: the banner space is produced, but the pads height is not the same for all the 4 pads (2 upper pads higher than 2 bottom pads).
Do you have any suggestions?
