Making data plots

[Earthednet-wp]

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.
Bill

Then you set the name of the last created group to whatever you like. You can now also delete that group by name.
