Dec 21, 2017 · I have a contour plot that I color using the Yellow-Green color map named YlGn The labels at the darker fields do not appear well, as they are black. Is there a method to color the labels in the inverse of the used colormap? i.e., to color the 0.39 label in white, and the 0.15 label in dark green, and the labels in-between accordingly.

Aug 25, 2016 · I am plotting my data into a contour map. The computations work on the translated values, so I need to put it back to its original value. On the fourth line of the code, is the re-translation process. However, when I plotted it the colorbar shows the relative values, and just a note of the shift value at the top of the color bar.

Sep 1, 2015 · I make a contour map with (say) 10 contours, like this: CS = plt.contour(X, Y, Z, levels=levels) Where levels is a list of 10 numbers. I'm pretty happy with the colors that matplotlib uses - I think it chooses 10 nicely spaced colors from the default color map - but how do I retrieve the actual colors used?
