<div dir="ltr"><div dir="ltr">HI Anne,<div>Please include ncl-talk on all replies so others can help and see the responses. You stated that you are still having trouble getting a box around your polar stereographic plot. I recommended for you to use gsn_polygon_ndc. Testing a simple example here though, it looks like gsn_add_polygon is best used for filling a shape, while gsn_add_polyline would be better for what you are looking to do. Here is a snippet of code that you can use to see how best to use gsn_add_polyline to draw a box, based off of polar stereographic example #1:</div><div><br></div><div><div>begin</div><div> a = addfile("$NCARG_ROOT/lib/ncarg/data/cdf/<a href="http://uv300.nc">uv300.nc</a>","r")</div><div><br></div><div> u = a->U(1,:,:) ; read July zonal winds</div><div><br></div><div> wks = gsn_open_wks("png","polar") ; send graphics to PNG file</div><div> res = True ; plot mods desired</div><div> res@gsnFrame = False</div><div> res@gsnPolar = "NH" ; specify the hemisphere</div><div> res@mpPerimOn = True</div><div> plot = gsn_csm_contour_map_polar(wks,u,res) ; create the plot</div><div><br></div><div> drawNDCGrid(wks)<br></div><div><br></div><div> x = (/0.3, 0.5, 0.5, 0.3, 0.3/)</div><div> y = (/0.2, 0.2, 0.6, 0.6, 0.2/)</div><div> polyres <span style="white-space:pre"> </span>= True</div><div> polyres@gsLineColor = "black"</div><div> gsn_polyline_ndc(wks, x, y, polyres)</div><div> frame(wks)</div><div>end</div></div><div><br></div><div>If you have further questions let ncl-talk know.</div><div>Adam</div><div><br></div></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Wed, Jan 16, 2019 at 2:39 AM Anne <<a href="mailto:anne.seidenglanz@unive.it">anne.seidenglanz@unive.it</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr"><div>Dear NCLers,</div><div><br></div><div>I'd like to put a rectangular box perimeter around a polar projection as is attached as example (not plotted with NCL).
