Dear ROOT users,
I have a data set stored into a tree from which I make a scatter plot, weighted by a specific quantity. I’d like to stack this onto another scatter plot, which derives from another data set which I have stored in another tree. Is there a method to stack two plots together, with ROOT deciding the upper and lower bins automatically?
The only place I can think of to start from is creating histograms from the two data sets, then somehow use
Add the histograms to this. I’d like to know if I’m on the right track, and if so, how I should progress. If this is completely incorrect, could somebody please advise me on how to handle two data sets in two separate trees, with the aim of making comparisons between the two sets of data?
Thanks in advance!
