You should also print out the inputs of the first plot function, dt_old, dt2, T_old, and T to see whether they have the same dimsizes. Furthermore you can easily know which plotting is erroneous by just commenting out one of them.</div><div class=""><br class=""></div><div class="">Jack</div><div class=""><br class=""><div><blockquote type="cite" class=""><div class="">On 27 Aug 2015, at 16:13, Lara Gunn <<a href="mailto:lara.n.gunn@gmail.com" class="">lara.n.gunn@gmail.com</a>> wrote:</div><br class="Apple-interchange-newline"><div class=""><div dir="ltr" class=""><p class="MsoNormal"><span lang="EN-GB" class="">Hi</span></p><p class="MsoNormal"><br class=""></p><p class="MsoNormal">I am running ncl 6.2.1 in cygwin</p><div class=""><span lang="EN-GB" class=""> </span><br class="webkit-block-placeholder"></div><p class="MsoNormal"><span lang="EN-GB" class="">I am

this isn’t the whole piece of code but the other graph in the image using
gsn_csm_x2y2 so that can’t be the cause of the error. There do seem to be some
errors in this because the gsn_polyline is on plot2 not plot one on the image
it creates, but if I put plot there instead it draws a mysterious line of the
first plot. All in all I am quite confused what I have done.</span></p><div class=""><span lang="EN-GB" class=""> </span><br class="webkit-block-placeholder"></div><p class="MsoNormal"><span lang="EN-GB" class="">I have
