Does NSBezierPath do decimation as well as interpolation? I didn't find it in the Class Reference. Or is there another class that does it? Or must I do the decimation before plotting the data with NSBezierPath?
Decimation reduces the original sampling rate for a sequence to a lower rate, the opposite of interpolation. The decimation process filters the input data with a lowpass filter and then resamples the resulting smoothed signal at a lower rate. In my application, the math generates hundreds of points for accuracy, for every one that needs to be plotted to make a decent looking plot. Signal processing theory says that you can't just throw away points, or you can generate errors. For example, I might generate 25,000 points and be happy to look at a 200 point plot. Throwing 25,000 points at NSBezierPath might swamp it, or at least run very slowly.
