| =============== | |
| `.Axes3D.contourf` differs from `.Axes3D.contour` in that it creates filled | |
| contours, i.e. a discrete number of colours are used to shade the domain. | |
| This is like a `.Axes.contourf` plot in 2D except that the shaded region | |
| corresponding to the level c is graphed on the plane ``z=c``. | |
