Once I set ‘debug' to be a local variable inside the function (gsn_contour_shade), then it all works as expected. So I do have a temporary fix if I replicate the function from gsn_code inside my script with the local variable “debug”. Maybe somebody can have a look and see what a more durable solution is.</div><div><br></div><div>Thanks,</div><div>Caspar</div><div><br></div><div><br></div><div><br></div><div><div><font face="Courier"><span style="font-style:normal;font-size:9px">begin</span></font></div><div><span style="white-space:pre-wrap;font-style:normal;font-size:9px"><font face="Courier"> </font></span></div><div><font face="Courier"><span style="font-style:normal;font-size:9px"><span style="white-space:pre-wrap"> </span>a = addfile("/glade/scratch/ammann/NEWMONT/pr_meanfield_DJF_2085.nc","r")</span></font></div><div><font face="Courier"><span style="font-style:normal;font-size:9px"><span style="white-space:pre-wrap"> </span>b = a->meanfield</span></font></div><div><font face="Courier"><span style="font-style:normal;font-size:9px"><br></span></font></div><div><font face="Courier"><span style="font-style:normal;font-size:9px"><span style="white-space:pre-wrap"> </span>wks <span style="white-space:pre-wrap"> </span>= gsn_open_wks ("x11", "coneff" )</span></font></div><div><font face="Courier"><span style="font-style:normal;font-size:9px"><span style="white-space:pre-wrap"> </span>res <span style="white-space:pre-wrap"> </span>= True</span></font></div><div><font face="Courier"><span style="font-style:normal;font-size:9px"><span style="white-space:pre-wrap"> </span>res@gsnDraw = False ; We're going to panel later, so don't</span></font></div><div><font face="Courier"><span style="font-style:normal;font-size:9px"><span style="white-space:pre-wrap"> </span>res@gsnFrame = False ; draw or advance frame.</span></font></div><div><font face="Courier"><span style="font-style:normal;font-size:9px"> <span style="white-space:pre-wrap"> </span>plot = gsn_csm_contour_map(wks, b(0,:,:), res ) </span></font></div><div><font face="Courier"><span style="font-style:normal;font-size:9px"><br></span></font></div><div><font face="Courier"><span style="font-style:normal;font-size:9px"> <span style="white-space:pre-wrap"> </span>opt = True</span></font></div><div><font face="Courier"><span style="font-style:normal;font-size:9px"> <span style="white-space:pre-wrap"> </span>opt@gsnShadeFillType = "Pattern"</span></font></div><div><font face="Courier"><span style="font-style:normal;font-size:9px"> <span style="white-space:pre-wrap"> </span>opt@gsnShadeLow = 3 ; Use fill Pattern #3</span></font></div><div><font face="Courier"><span style="font-style:normal;font-size:9px"> <span style="white-space:pre-wrap"> </span>plot <span style="white-space:pre-wrap"> </span>= gsn_contour_shade(plot,0.,-999, opt) ; should be target</span></font></div><div><font face="Courier"><span style="font-style:normal;font-size:9px">; <span style="white-space:pre-wrap"> </span>dummy <span style="white-space:pre-wrap"> </span>= gsn_contour_shade(plot,0.,-999, opt) ; dummy: also assignment problem</span></font></div><div><font face="Courier"><span style="font-style:normal;font-size:9px"><br></span></font></div><div><font face="Courier"><span style="font-style:normal;font-size:9px"><span style="white-space:pre-wrap"> </span>draw(plot)</span></font></div><div><font face="Courier"><span style="font-style:normal;font-size:9px"><span style="white-space:pre-wrap"> </span>frame(wks)</span></font></div><div><font face="Courier"><span style="font-style:normal;font-size:9px"><br></span></font></div><div><font face="Courier"><span style="font-style:normal;font-size:9px">end</span></font></div></div><div><br></div><div><br></div><div>
