WebGet the free "Contour Plot" widget for your website, blog, Wordpress, Blogger, or iGoogle. Find more Mathematics widgets in Wolfram Alpha. WebFrom this you can find the maximum contour and the minimum contour. In the example you posted I found N = 10 contours in 0.1 increments, several of which were empty. I still maintain that you may be better off generating your data, interpolating it and plotting it later but this approach will work if you really want to extract contour lines.

WebAug 2, 2011 · Yes, but under "More Information," it says "ContourPlot superimposes the contour lines associated with all of the equalities" about the third command, which means that the countour contains a point if it is a solution to ANY of the equations instead of what I am looking for, which is the set of points that are solutions to ALL equations. WebWith ContourShading->False, regions between contour lines are left blank. With ContourShading->Automatic, regions are colored based on the setting for the option ColorFunction. The default is to color the regions with gray levels running from black to white with increasing height. christopher t calio
Postprocess a ContourPlot to find minimum and maximum values?
WebThe contour lines we use to make a contour plot are a set of all x and y values which, together, produce a specific z-value. If you're working with some other 3D graph then, you'll want to check to find which values of x and y together produce z. The easiest way to do this is to set a fixed value for one variable and then solve for the other. WebIn determining how to color regions between contour levels, ContourPlot looks first at any explicit setting given for ContourShading, then at the setting for ColorFunction. … Wolfram Science.
