Yes, we do have such an example.  See, <http://plplot.org/examples.php?demo=32>.

We have implemented no high-level API for such plots.  Therefore, this
C-only example was implemented with more fundamental PLplot API calls
by one of our users back in 2009.  Of course, that lack of high-level
API does give you complete freedom to change the style of this plot
anyway you like using lower level API calls.

If you have a high interest in such plots and a good idea for what the
high-level API for such plots should look like without constraining
users too much with regard to style, we are certainly open to more
contributions in this area.
