Accepted Answer. The problem is your data goes from [-6.5 8]. The 16 contour lines have been drawn for that. Then when you call caxis, you get rid of any color distinction above 2 or below -2 (>2 all have same color, <-2 all have same color). This does not affect where the actual contor lines go, though. Just the range of values used to assign.

Description. c = lines returns the lines colormap as a three-column array with the same number of rows as the colormap for the current figure. If no figure exists, then the array contains 256 rows. Each row in the array contains the red, green, and blue intensities for a specific color. The intensities are in the range [0,1], and the color. contour (Z,v) draws a contour plot of matrix Z with contour lines at the data values specified in vector v. The number of contour levels is equal to length (v). To draw a single contour of level i, use contour (Z, [i i]). contour (X,Y,Z), contour (X,Y,Z,n), and contour (X,Y,Z,v) draw contour plots of Z.

Second, the objects returned by these functions no longer have any children. That means you can't get to the low-level objects.

Plot a Color Map Using the meshc() Function in MATLAB. To plot the color map of the given matrix, you can use the meshc() function, which plots the color map of the variable on a given x and y-axis and adds the contour plot under the mesh plot.

Create or import dataset for making the plot. We can reverse the colormap of the plot by using two methods are discussed above. By using the first method: First we have to get the colormap using cm.get_cmap ("name_of_cmap") and let be stored in variable named as "orig_map". Then we have to reverse the original colormap for that we use.
