I have about 10,000 root files each with three histograms, and so I am looking for a fast way to convert the data from these histograms into text files. The only important part of the data is the total number of entries in each histogram. There are some posts here about how to combine histograms; however I don’t need the total number of entries summed, I need to find the maximum amount of entries in a single histogram.
Having histogram names as numbers or starting by a numbers is a very bad idea as they are illegal C++ variables names. Before trying to work around this it would be better and much simpler for future use, if you can regenerate your histograms with proper names. Is it possible ?
