Comment (by Michael Koch):

 I did figure out that the "draw" option must be set to "full". But that
 really wasn't clear in the documentation. I suggest the following better
 documentation for the "draw" option:

 Set the draw mode.
 Available values are:
 'scale'  Use blending, that means the samples are drawn darker where the
 slope is larger. This is the default.
 'full'   Draw all samples with full intensity. This is useful for higher
 values of n.
