[ncl-talk] draw filled markers with different colors for markers' boundaries

[Adam Phillips]

Hi Sha,
I have accomplished this by drawing a set of filled markers first (say a
filled circle #16), then drawing the exact same markers but this time use
an
unfilled version (hollow circle #4). As a simplified example:
res = True
res at gsnDraw  = False
res at gsnFrame = False
...
res at xyMarkerColor = "black"
res at xyMarker = 16
plot = gsn_csm_xy(wks,time,arr,res)
res at xyMarker = 4
res at xyMarkerColor = "red"
plot2 = gsn_csm_xy(wks,time,arr,res)
overlay(plot,plot2)
draw(plot)
frame(wks)

You may have to alter the thickness or size of the markers (using
xyMarkerSizeF or xyMarkerThicknessF), but the above should get you started
down
the right path.

Hope that helps. If you have any further questions please respond to the
ncl-talk email list.
