Re: Plotting a class function?

I was hoping to create at TF1 for each instance that would automatically get made when object was instanciated, but I haven't been able to figure out anyway to do it reasonably, so I'll just have to settle for making object and calling it from c-function on a case-by-case basis.

Thanks anyway, Art S.
