Would Chapter 11, section 11.1 Showing Paths of the MetaPost manual, be
any help here?
Below is a MWE of a random path of curves and straight lines. The points
are shown using drawpoints. The arrow path and control lines are also
shown and are better described in the Metapost manual.

\setuppapersize [A4,landscape]

path pat;

for a = 1 step 1 until 10:

y:= uniformdeviate(10) +10;
if odd a:

else:

A better coder than me may be able to incorporate it into what you require.

I would like to be able (during development) to draw paths where the points of
the path (and maybe thing slike directions) are visualised. E.g. a path where
each pair in teh path is also drawn as a dot and maybe teh directions drawn as
small arrows.
Does someone have such a beast lying around?
