[ncl-talk] Adding a marker on a contouring map

[Guido Cioni]

After looking at your script I think the problem is related to the fact that you draw the plot and advance the frame before.  

Could you try the following? 
Add res at gsnFrame = False and res at gsnDraw = False  to the plot resources.
add the call frame(wks) at the end of the script, after draw(plot)

Let me know whether that resolves the issue.
