ROFL. :)

Well, I guess the way it's done in most audio editors is that you draw a 
vertical line between the min and max (and maybe also the rms on top of 
that), if a single pixel has to represent multiple samples, and the 
usual connect-the-points-with-lines thingy (or splines, if you prefer 
smooth curves), when zoomed in to the sample or sub-sample level. Is 
there a better way?
