Hi Everybody, Sorry about another simple question (my only excuse is that I've only just started!). I want to plot a very simple set of histograms (in black and white) all overlayed onto each other, so I basically want to choose lots of different line styles eg. dashed, dotted etc. I've looked at all the documentation and I thought that maybe SetHistLineStyle will do the trick. Firstly, am I right in thinking this? Secondly, is there a list that gives all the possible options? Thirdly, and most importantly, if this is the correct thing to use, I can't get it to work by typing, for example, h1->SetHistLineStyle(somenumber); if my histogram is h1. The error that comes up is the following: Error: Can't call TH1F::SetHistLineStyle() in current scope FILE:/tmp/file9uApj4_cint LINE:1 Possible candidates are... filename line:size busy function type and name (in TH1F) filename line:size busy function type and name (in TH1) filename line:size busy function type and name (in TNamed) filename line:size busy function type and name (in TObject) filename line:size busy function type and name (in TAttLine) filename line:size busy function type and name (in TAttFill) filename line:size busy function type and name (in TAttMarker) filename line:size busy function type and name (in TArrayF) filename line:size busy function type and name (in TArray) *** Interpreter error recovered *** So, what do I need to do?
