Hi Paul,
In IDL 8.1 you will be able to plot onto a map projection using the
Plot() function, and it will warp the plot data to that projection.
For right now, you might try added a new map projection next to your
existing map, and then using the Polyline() function to plot the
actual points. However, I'm not sure how you would add the Axis...
