Integer values on x-axis of multi-graph

[faca87]

Hello, I’ve to set only integer values on the x-axis of a multi-graph becaues of the number of targets is an integer.
Following an example of @couet, I wrote

mg->GetXaxis()->SetNdivisions(8);

but the plot shows values as for example 2.5, 3.5 etc

emitarnum.cpp (2.4 KB)
Emittance_numb_target_C.txt (59 Bytes)
Emittance_numb_target_Be.txt (63 Bytes)

Thank you

Try experimenting yourself to understand it and find a value that works for what you want.

There is several ways to achieve this, but as you already set the number of divisions in your macro, the simplest is:

mg->GetXaxis()->SetNdivisions(6);
