Hi Damir, I assume your class is compiled, not interpreted (a class defined interactively cannot inherits from a compiled class). If your class is compiled, the only thing I acn suspect is some overwriting when your function DrawHist is called. Let me know the result of your investigations when you remove gradually statements from your DrawHist function.
