A la GTK : linear/"bitmap" (each pixel has an independant value)/spline. now THAT would be useful.

I think that a widget shouldn't create peakfiles. They should be provided to it with another thread, but what if I have peak files and I don't want a multithreaded app (because I use bindings of those apps in a nothreads-perl-Qt prog ?) Shortly : A and B shall be separated and optional to each other.
