Re: Embedding scatterplots in NCL map space.

Hi Bill,

If you create the individual plots using lat/lon for the y/x axes, then you can use "overlay" to overlay the scatter plots on the map.

See attached. It's not very pretty, but hopefully it illustrates how to do this.

I may be able to use your the polymarkers by scaling each subset's x-y coordinates by the chips latitude and longitude. Thanks for getting me started...

Ideally we'd like to take the plot scene, such as the one in this email, and overlay tiny scatterplots (no axes or labels, just the scatter dots) over the individual subsets (shown by the color chips). Does NCL have the capacity to do this in any capacity?
