# The Amazing Bi-Plot

This article gives а demo of a way to do high-resolution grey-scale graphics. That’s right! Though I may be stretching the definition, we’ll actually see the ZX81/TS1000 display a high-res scale of three shades – black, white and grey. A quote I just invented runs, “Three shades doth verily a grey-scale maketh.”
