Dear experts,
The following is the code, I’d like to tune the range of Yaxis (0,1), but the function ”SetMinimum“ does not work. The attachment is the code and output.
could you please help me? Thank you very much. huatu.C (1.0 KB)
Note that first you have to draw the graph, then update the canvas (or gPad), and then change the limits (because of the way SetMin/MaxRadial are implemented in the ROOT code).
