- I need to plot a graph with a very large number of points (15,000+)
- on a screen/printer with a much lower resolution (say 1000x1000).
- Joining all the input points is very wasteful and verbose since most
- of the line segments don't even span a pair of adjacent pixels. Is
- there some standard method for compressing the input data to weed out
- points that wouldn't affect the graphical display noticeably? One
- idea I had is to throw away the interior points of a run of nearly
- colinear points.
