<div dir="ltr">Dear ncl-talk,<div><br></div><div>I'm trying to plot storm tracks for a variety of storms, one file for each storm. My plan was to overplot each track and then draw the plot at the end after reading all files and tracks. When I do this, I get the err<font face="arial, helvetica, sans-serif">or, "warning:TransformPostDraw: tfPolyDrawList element 868 is invalid". I get a number of these errors. While my labels plot fine, my lines and markers don't show up, obviously because of the error.</font></div><div><font face="arial, helvetica, sans-serif"><br></font></div><div><font face="arial, helvetica, sans-serif">I looked at unique_string example to avoid this, but couldn't find out how to correctly implement it, so I decided to create a large "dum" array for each polyline/marker, but I got the same error. I can't figure out why its still doing the error even when I'm keeping the id's.</font></div><div><font face="arial, helvetica, sans-serif"><br></font></div><div><font face="arial, helvetica, sans-serif">Any help much appreciated.
