[ncl-talk] Polymark Draw Order In Panel Plots

Hi All,

    I hope I have an "easy" question. I'm paneling some (HRRR) model data, and I'd like to overlay some polymarkers signifying actual observations for the first forecast hour, where data is available. This plot looks like: http://operations.nysmesonet.org/~nbassill/sample/mediandewpoint.png (you'll note the dots on the map for 11 am).


My question is "How can I have these polymarkers on top of the map outlines?"


I've played around with some draw orders and framing, but nothing seems like it works (or maybe it does work, but NY isn't masked out).


Here's the crude outline of relevant steps (I don't regularly use panel, so I can't be confident these are all needed):


-------


... (earlier code)

res at gsnDraw  = False
res at gsnFrame = False

res at mpOutlineOn             = True
res at mpFillOn              = True
res at cnFillDrawOrder             = "PreDraw"


plot = new(15,graphic)
do i=0,14
plot(i)= gsn_csm_contour_map(wks,data(i,:,:),res)

end do


(polymarker section, including: mres at tfPolyDrawOrder= "PostDraw")


(panel resource stuff)


gsn_panel(wks,plot,(/4,4/),panelres)


-------------


Any assistance would be very much appreciated!
