yep me too, well 3d surface plots would also be nice to have, but I can 
live without.

I would use an OO API where one window/image/output graph is 
represented by an object, and then you have functions to

keep it simple I would just send dense arrays to it (which are close to 
the C api), and then have utility functions that convert ranges,... to 
dense arrays, but maybe I am biased because I have a good library to 
handle dense arrays.
I would say that a reasonable goal is that the library could cope 
directly to plot of 1'000s of points at least for the simple 1D plot
