[ncl-talk] Attaching a map outside (or inside) of a plot

It looks like you are doing everything correctly, because you have a unique
id for every marker you add, and you are setting a different color every
time.

However, it's possible that the color indexes you've chosen all map to
different variations of yellow in your current colormap. I would recommend,
as a test, and also for "cleaner" code, to use named colors, rather than
color indexes.

For example, instead of:

  colors2 = (/2,20,10,14/)

try:

  colors2 = (/"yellow","blue","forestgreen","purple"/)

and let me know if you are still getting all yellow points. If you do, it
would help if we could see the full code, and a sample plot.

Thanks,

--Mary
