Mesh spacing
type: item
description: Can anyone offer me any advice? The mesh grid that covers the surface plot I have produced is causing me one or two problems. I have made the lines as small as I can but my boss is still not happy with the plot. As I move the plot around areas of the plot become darker as the concentration of lines increases. Is there any way that I can reduces the number of lines on the mesh grid, and hopefully this will solve my problem. Many Thanks Neil.

Depending upon your application and needs, of course, the practical upper limit on most surface plots is an array of about 80 by 80. Arrays larger than that just produce too many lines to be easily visualized in a normal-sized window. I like a surface plot of about 60 by 60, so I find myself writing a lot of code that looks like this: s = Size(array) IF s[1] GT 60 OR s[2] GT 60 THEN $ Surface, Congrid(array, 60, 60) ELSE Surface, array Cheers, David ---------------------------------------------------------- David Fanning, Ph.D. Fanning Software Consulting Customizable IDL Programming Courses Phone: 970-221-0438 E-Mail: davidf@dfanning.com Coyote's Guide to IDL Programming: http://www.dfanning.com
