Draws contours and/or colourmapped levels associated with a function of the form z = f(x,y) defined on a regular (x, y) grid. It enables you to create vertex, grid and surface models in Cartesian, cylindrical and spherical coordinate systems. Contours of matrix data can be plotted using non-linear user-supplied spacing. A level plot is a type of graph that is used to display a surface in two rather than three dimensions - the surface is viewed from above as if we were looking straight down and is an alternative to a contour plot - geographic data is an example of where this type of graph would be used. A contour line (also known as a level curve) for a given surface is the curve of intersection of the surface with a horizontal plane, z = c.

In the demo above, every point in the graph has an x and y value. Either way, you can draw or this Let us show you how this works. The functions semilogx, semilogy, and loglog are similar to the plot function, but produce plots in which one or both of the axes use log scales. To convert the heatmap to a contour plot, we need to select 'Contour map' from the TRACE popover, as shown in the figure below. It looks almost correct except for a slight misalignment of the 0,0 coordinates of both plots. The diff from b = -2 to b = 0 is summarized at 0 on the x-axis and the diff from b = 0 to b = 2 is summarized at 2 on the x-axis.
