[ncl-talk] Polymark Draw Order In Panel Plots

[Adam Phillips]

Hi Nick,
Draw orders can be tricky, especially in this case when multiple layers
have to be drawn in precisely the right order, and there's only 3 settings
possible in the *DrawOrder resources.
Try:
res at cnFillDrawOrder             = "PreDraw"
res at mpFillDrawOrder = "Draw"
res at mpOutlineDrawOrder = "PostDraw"
mres at tfPolyDrawOrder= "PostDraw"
if that doesn't work try switching the mpOutlineDrawOrder  to  "Draw"

Let ncl-talk know if that doesn't work. If it doesn't, it might be best to
send along the complete graphics section of your script.
