+Simple Contours in a Slice
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Sometimes it is useful to plot just a few contours of a quantity in a
+dataset.  This shows how one does this by first making a slice, adding
+contours, and then hiding the colormap plot of the slice to leave the
+plot containing only the contours that one has added.
