An alternative way, if it's just pixel-plotting you want, is to 'poke directly to an image. Example... rebol [] plot: func [image x y color][ x: to-integer x + .5 y: to-integer y + .5 poke image y * image/size/1 + x color ] pic: to-image 200x200 y: 50 for x 0 199 1 [ plot pic x y red y: y + .5 ] view layout [image pic] I could've used a pair for the xy values, but it seemed simplier not to.
