Hi @rmthomas ,
Doing it the way @txnelson suggests is probably the easiest -- or you can also right click one of the cells (say a 0), choose Select Matching Cells, then right click a row number and select Color, repeat for the other group (1).
Using the legend method will use JMP's default color scheme, which will be red and blue for the two levels. If you do it by selecting the matching cells way, you can choose the color yourself. When doing it the Legend way, you can go in and modify the legend to be a color scheme that you define, but it's rather involved and probably not worth the time to do it that way.
It also sounded like you were interested in changing the 1/0 text color in the right y-axis of the graph. If that is true, it can be done, but it too is a rather involved process and probably not worth it unless you currently or plan on using JSL to get there.
Good luck!,
DS
