You are right, #xTicks: would do the trick, but it's not there. The
reason I didn't put it in the pie layout options is that the
documentation says it's only available on line and bar layouts.
http://media.liquidx.net/js/plotkit-doc/PlotKit.Layout.html
As it turns out, the documentation is wrong and it works fine with a pie
layout.

I published a new version (PlotKit-pmm.4) that adds #xTicks: to all
layout options, and updated the included demo to set the labels. I
also included a patch from the PlotKit mailinglist that allows to
disable filling and stroking for line charts.

A dataset is really just a collection of points and a string. If you
don't find the API a paragon of OOP then I agree. It's just a very
close mapping of the existing PlotKit API. This makes life for me much
easier.

If nothing is displayed this in general means that there was a
JavaScript exception. Firefox and Extensions (Javascript Console,
FireBug, Javascript Debugger) help in these cases.

Cheers
Philippe
