THStack using drawing in wrong order for log scale

[aaronsw]

TList claims to have a sorting function, but it looks like it just sorts based on the names of the objects. Looking at the TList::Sort (Bool_t order=kSortAscending) function, it doesn’t appear to have a way to specify the comparison function.

This problem is looks like it wasn’t resolved here:

How can I sort histograms in TList?

Hi, TList l; l.Add(new TH1F("h4","h",1,0.,1.)); l.Add(new TH1F("h1","h",1,0.,1.)); l.Add(new TH1F("h3","h",1,0.,1.)); l.Add(new TH1F("h2","h",1,0.,1.)); l.Sort(); l.First()->GetName(); works perfectly for me. Glad you found a solution. Axel.
