Re: Overlays (basemap+2 contours) in Panel Plot

you need to set up an array for the plots to be held and not draw or frame them as gsn_panel will do this for you. I think this will work, may be an issue with continually overwriting plot2 & plot3 though.

untested but I think this will work.

Alan.

e.g.

plot = new( 4, graphic)
do i=0,3
  res@tiMainString = "Stream Function and Velocity Potential 850 hPa ~C~ ~Z55~ "+var(i)+ "
  plot(i) = gsn_csm_map_ce(wks,mpres)
  plot2 = gsn_csm_contour(wks,sf(i,:,:),res)
  plot3 = gsn_csm_contour(wks,vp(i,:,:),cnres)
  overlay(plot(i),plot2)
  overlay(plot(i),plot3)
end do
  pnlres = True
  pnlres@txString = ""
  pnlres@gsnPanelLabelBar = True
  pnlres@lbLabelAutoStride = True
  pnlres@gsnPanelDebug = True
  gsn_panel(wks,plot,(/2,2/),pnlres)

end
delete(plot) ; if you have ncl6.x delete( [/ plot, plot2, plot3, wks/] )
delete(plot2)
delete(plot3)
delete(wks)
