Re: XY Plots over a Map

Hi Soumik,
Yes. You can do this by manually overlaying, setting gsnFrame = False,
and by using the various vp resources.
Something like this:

wks = gsn_open_wks("ps","test")

res = True ; spatial plot resource list
res@mpMinLatF = 10.
res@mpMaxLatF = 75.
res@mpMinLonF = -170
res@mpMaxLonF = -45
res@mpCenterLonF = (/res@mpMinLonF+res@mpMaxLonF)/2
.....
res@gsnFrame = False ; do not advance the frame, as we wish to
manually overlay xy plots onto page
plot = gsn_csm_contour_map(wks,data,res)

res2 = True ; xy resource list
res2@vpXF = 0.2 ; placement of left border of xy plot along x-axis
of page in NDC units (0->1)
res2@vpYF = 0.8 ; placement of top border of xy plot along y-axis of
page in NDC units (0->1)
res2@vpWidthF = 0.2 ; width of XY plot in NDC units (0->1)
res2@vpHeightF = 0.2 ; height of XY plot in NDC units (0->1)
....
res2@gsnFrame = False ; do not advance the frame
plot2 = gsn_csm_xy(wks,val,pdf0,res2)

res2@vpXF = 0.35
res2@vpYF = 0.6
plot2 = gsn_csm_xy(wks,val,pdf1,res2)
drawNDCGrid(wks) ; draw the NDC grid in the background so you can
better choose your settings for vpXF/vpYF
frame(wks) ; advance the frame

See the vp resources here:
http://www.ncl.ucar.edu/Document/Graphics/Resources/vp.shtml
and the drawNDCGrid documentation here:

Good luck,
Adam
