"same" and "a4" in one draw option

[hajar]

I want to draw tow graphs and one histogram in one canvas like below, when I use “a4” and “same” together for drawing option, graph1 and the histogram will be removed.

hAPx->Draw(); //histogram
gx2->Draw(“samepc”); //graph 1
gx3->Draw(“sameA4”); //graph 2

thanks

same is not a Graph Drawing option. I guess you want to do something like that:

hAPx->Draw(); //histogram
gx2->Draw(“pc”); //graph 1
gx3->Draw(“4”); //graph 2
