The following tutorial illustrates how to store histograms in a tree: https://github.com/root-project/root/blob/master/tutorials/tree/htest.C

Keep in mind that this is storing a set of histograms per event. If your histograms summarize all the events in a tree, it would actually make sense to have them in the ROOT file but not in a tree. If you have many such histograms and you want to group them, you can create directories in the ROOT file and place the histograms in different directories, as shown in https://github.com/root-project/root/blob/master/tutorials/io/dirs.C
