Dear Root users,
I’ve been filling TH1D histograms with my defined variable D by
I’d like now to fill a TH2D histogram and plot D against a second variable C, so it would be D on the x-axis and C on the y-axis. I’ve spend ten minutes looking in the guide and now I have given up, can someone tell me the command line to fill, I guessed
h2->Fill(D,C); but I’m guessing this is a weight, not what I wanted?
