Thanks. > > David Relyea > Hi David, we of PHENIX have a simple-minded root class which maintains "strip-values". To display, you hand the object a TH1F and get it back filled and display it. The nice thing is that it's simplistic, and you segregate the strip value maintenance from the display aspect -- it is all you can do with a histogram, so you don't reinvent stuff.
