<div dir="ltr"><div><div><div><div>Hi Izidine,<br></div>Thank you for providing your data via dropbox as it helped me to quickly diagnose the issue.<br><br></div>In this case, I think the slowdown is happening because you are telling NCL to create ~20 contours in your plotB* plots. Even though you are telling NCL to not draw the lines, their positioning is still computed when you call ShadeLtContour, and the contouring gets quite dense. The contouring is what is taking so long. The solution is to create fewer contours.<br><br></div>Change these lines:<br>res2@cnLevelSelectionMode = "ManualLevels" <br>res2@cnMinLevelValF = 0.00 <br>res2@cnMaxLevelValF = 1.05 <br>res2@cnLevelSpacingF = 0.045 <br><br></div>to these lines:<br>res2@cnLevelSelectionMode = "ExplicitLevels" <div>res2@cnLevels = 0.045<br><br></div><div>I did that and the plots came out quite quickly.<br><br></div><div>If you have any further questions please respond to the ncl-talk list.<br></div><div>Adam<br></div><div><br></div><div><br></div></div><div class="gmail_extra"><br><div class="gmail_quote">On Wed, Aug 19, 2015 at 4:17 AM, Izidine Pinto <span dir="ltr"><<a href="mailto:izidinep@gmail.com" target="_blank">izidinep@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><div>Dear NCL users<br><br></div>I'm plotting precipitation trends and overlying with the probability (p<0.05)<br> ..... <br> plotA0 = gsn_csm_contour_map_ce(wks,trend_jjas,res) <br> plotB0 = gsn_csm_contour(wks,prob_jjas,res2)<br> plotB0 = ShadeLtContour(plotB0, 0.0499, 17) ; shade all areas less than the 0.05<br> .....<br><br></div>However, when it comes to create the panel plot it takes around 2 hours just to print the figure in .eps <br><div><br></div><div>Is there any way to improve this time or I'm doing something wrong in the script? <br><br></div><div>I've attached the working example and the data can be found here (<a href="https://www.dropbox.com/sh/1srk2adshj8f4n0/AAA8J9L-hEhZshCsXkCAFycua?dl=0" target="_blank">https://www.dropbox.com/sh/1srk2adshj8f4n0/AAA8J9L-hEhZshCsXkCAFycua?dl=0</a>)<br><br></div><div>Thank you <br></div><span class="HOEnZb"><font color="#888888"><div> Izidine<br></div><div><br clear="all"><div><div><div><div>
