I think this is exactly what you need. At 1024 x 768, a monitor is
capable of producing not better than 85 points per inch. Resample your
large array to the desired resolution and plot it. PLOT will do this
anyway (on a visual level), but a lot less efficiently.

If the axis you plot against is 5" long, then the maximum number of
points you'll be able to see is < 500. Use CONGRID for plotting:

plot, congrid(a, 500)

works very fast.
