Dear all, I want to plot two graphs on the same plot. I have used this but its not plotting. TGraph *gr1 = new TGraph(n,x1,y1); TGraph *gr2 = new TGraph(n,x2,y2); gr2->SetMarkerColor(2); …

{ const int n = 10; double x1[n] = {0,1,2,3,4,5,6,7,8,9}; double x2[n] = {0,-1,-2,-3,-4,-5,-6,-7,-8,-9}; double y1[n] = {1,2,3,4,5,5,4,3,2,1}; double y2[n] = {5,4,3,2,1,1,2,3,4,5}; auto gr1 = new TGraph(n,x1,y1); gr1->SetMarkerColor(3); gr1->SetMarkerStyle(20); auto gr2 …

A TMultiGraph should automatically compute the X and Y axis ranges to make all data points visible.

Another approach (not using a TMultiGraph):
