Plotting data points

[ksmith]

#include <TGraph.h>
#include <TMultiGraph.h>
//...
auto mg = new TMultiGraph();
mg->Add(g);
mg->Add(g1);
mg->Draw("AP");
//...

FYI:

Getting the same histograms after cuts

Remark on the way to post code snippets: When you post pieces of code on the forum enclose it with ``` . That makes your post much more readable (I systematically edit your posts that way) . So do: ``` // this is a C++ piece of code. ``` And it will display as: // this is a C++ piece of code.
