Filling Contours

The Fill contours setting in the original contour property sheet controls whether the contour levels are filled or not. Change the Fill contours setting to True.


Note
You must also change the Use palette color setting to True as well before colors can be used. After that, you can choose or set your own color scheme from the Levels Color Table  Edit color table function.

The contour colors are now more distinctive.

Even more detail can be added by increasing the number of levels in the contour display. Change the Number of levels from 6 to 20.

The color set for each of the original seven levels is repeated every set of seven within the 20 new levels.
