Folks, Thanks for all the good ideas. For line plots, I do create a line and set the points of the line to the values I want. For plots with discrete symbols (there may be many thousands), I draw directly into an image using a derivative of code I got from Colin's simple draw program. This works well, but I noticed a huge slowdown going to livecode 7, so I'll have to spend some time optimizing my repeat loops.
Grouping plot elements will simplify my code, and since I rely heavily on snapshots, I really appreciate that the dev team did some work to make it more robust. Thanks again for the ideas and help.
