Hi Mary,
Thank you for your quick reply. I tried setting some to predraw rather
than draw, and no change. Here is my figure script, where the map
outline disappears with res2 at mpOutlineDrawOrder = "Draw" (as it is
below). What I would like is the map outline to be under all contours,
vectors, and the polymarkers.
Thank you!
Stephanie
