<div dir="ltr">Hi Laura,<div>You do not need to use gsn_coordinates to handle missing values in panel (or single) plots. If your plot call is hanging, there's two possibilities that stand out above others:</div><div>1) You have very tight gradients in your data, whether due to chosen contour levels, a high data resolution, or spatially highly variable data. If this is the case, try setting cnFillMode = "RasterFill" (and cnRasterSmoothingOn = True if you want smoothed fields). You can also try smoothing your data (using smth9_Wrap for example), and changing your contour levels. Perhaps most importantly, check that your _FIllValue attribute is set correctly. </div><div>2) Your data has NaN's in it. Check for this by using isnan_ieee. </div><div><br></div><div>If you continue to have issues let ncl-talk know..</div><div>Adam</div></div><br><div class="gmail_quote"><div dir="ltr">On Fri, Aug 3, 2018 at 9:00 AM Laura Fowler <<a href="mailto:laura@ucar.edu">laura@ucar.edu</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div>Hello:</div><div><br></div><div>I wrote a ncl script to make a panel plot (/3,2)/).
