Visit the installation page to see how you can download the package and get started with it. We use the same code as before, with the following line changed (I have added zorder=1 to ensure that the contour plot is below the scale bar as lower z-order numbers are drawn first): If we use contourf instead of contour, we can create filled contours instead of just contour lines: In this case, a lot of the finer details from imshow are not well captured in contour or contourf.
