Re: put map on top

Hi Xiaoming ,
Try adding the following resources:
res@gsnDraw = False ; do not draw the plot
res@mpOutlineDrawOrder = "PostDraw" ; draw the map outline last

and then draw the trajectories and map and advance the frame like this:
plot = gsn_csm_map(wks,res)
gsn_polyline (wks, plot, 360-lat_long(:,1) , lat_long(:,0), resp)
draw(plot)
frame(wks)

The mpOutlineDrawOrder resource may or may not be necessary. Let the
group know if that doesn't work. Adam
