<div dir="ltr"><div><div><div>Hi Tabish,<br></div>Generally speaking, graphics creation will take longer if you explicitly ask for contours that are quite close together (or if you ask for a large number of contours) in noisier fields. I am guessing that NCL is choosing contours that are not as close or are fewer in number than the ones you are choosing.<br><br></div>You can also try setting the following resources:<br></div><div>cnFillMode = "RasterFill"<br></div><div>or<br>trGridType = "TriangularMesh<br></div><div><div><div><br></div><div>Hope that helps. If not, or if you have additional questions please email ncl-talk.<br></div><div>Adam<br></div><div><br> <br></div></div></div></div><div class="gmail_extra"><br><div class="gmail_quote">On Wed, Aug 26, 2015 at 1:09 AM, Tabish Ansari <span dir="ltr"><<a href="mailto:tabishumaransari@gmail.com" target="_blank">tabishumaransari@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div class="gmail_default" style="font-family:trebuchet ms,sans-serif">Hi<br><br></div><div class="gmail_default" style="font-family:trebuchet ms,sans-serif">I have been trying to produce some contour maps from data of around 300x300 grid points and more using gsn_csm_contour function.<br><br></div><div class="gmail_default" style="font-family:trebuchet ms,sans-serif">When I use Manual Levels mode, the plot seems to take a lot of time and the system hangs- the plot is never produced.
