Histograms with different scales

Hi,

I’m trying to plot three histograms on a canvas, each with different scales. I’ve followed the tutorial and successfully managed to plot two histograms with different scales on the same canvas but I’m having difficulty adding a third. Is it possible to do this?

Many thanks,

Lisa

The example you started from is very likely the one in which 2 pads with different x and y coordinates are plotted on top of each other and a 2nd axis is plotted in the top pad using TGaxis. You can do the same with a 3rd pad. The only problem will be to find the place where to put the axis. Just shift it on the left or right (if it is the Y axis).
