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.
You can have a look:
