I have created TProfile2D histograms in my work to analyse graphically the dependencies between different data.
The root user guide writes this about TProfile2D histograms:
. TProfile: one dimensional profiles
. TProfile2D: two dimensional profiles
Profile histograms are used to display the mean value of Y and its RMS for each bin in X. Profile histograms are
in many cases an elegant replacement of two-dimensional histograms. The inter-relation of two measured
quantities X and Y can always be visualized with a two-dimensional histogram or scatter-plot. If Y is an
unknown but single-valued approximate function of X, it will have greater precisions in a profile histogram than
in a scatter plot.
My question is the following:
Is it true, that by default, when I draw a TProfile histogram, then I get the mean of the values in each bin?
How can we plot only the RMS of the values in each bin? I didn't find this imformation anywhere.
Thank you for your help.
