I want to get point values from TMultiGraph.
If I have TGraph object I can write this code:
const int N_points = graph->GetN();
double x, y;
for(int i=0; i < N_points; i++)
graph->GetPoint(i, x, y);
cout << "f(" << x << ") =" << y <<endl;
But how to do this in case of TMultiGraph object, if I have several graphs in it?
I don’t see sothing like GetPoint().
Could you help me?
Thank you in advance.
Best regards, Vladislav.
I found this talk:
But how to iterate?
Could you give simple working example?
This one gives an example:
