To see the triangulations, opt to "Save Triangulations".</SPAN> but is there somewhere that provides more details? I need to describe the process for a publication; reviewers are grumbling about me using a "black box" analysis.</P><P>Thank you.</P></BODY></HTML> Fri, 06 Sep 2013 05:57:53 GMT https://community.jmp.com/t5/Discussions/Contour-plot-algorithm/m-p/7374#M7368 dzeke 2013-09-06T05:57:53Z Re: Contour plot algorithm? https://community.jmp.com/t5/Discussions/Contour-plot-algorithm/m-p/7375#M7369 <HTML><HEAD></HEAD><BODY><P>Contour Plot uses <A href="http://en.wikipedia.org/wiki/Delaunay_triangulation">Delaunay triangulation</A>.
