Ok, that works but it is not very intuitive. Why should the choice
of the symbol displayed at a data point affect the how points are
connected?

Use psym=3 (or 2, if you want *'s at the points)

In IDL, "plots" _does_ work. If you don't want lines drawn between
consecutive points, use the keyword "psym"... psym=3 gives
dots, other values give stars, squares, diamonds, etc...
I don't know if this also works in pv-wave. Hopefully it does.
