I am filling TH1 histogram with data, I want to know what is the minimum /maximum values of x that was filled by data. When I use:
h->GetXaxis()->GetXmin(); // it will return to 0 or to the value the I defined as the minimum for h.
But I want the real value of x minimum/maximum (after filling from data points) so I can redefine the limits of x axis.
Could anyone tell me how to do that?
