Thanks, Steve, for this suggestion which I really like. To the PLplot developers here: I think we should implement standard example x00 in C similar to the way Steve described with the emphasis on keeping it an extraordinarily simple plot as described in http://plplot.sourceforge.net/docbook-manual/plplot-html-5.9.9/simple.html. We should then propagate example 0 to all our languages. If the developers here agree with this plan, then I volunteer to take responsibility for implementing the C example part of this as well as the trivial build-system and script changes necessary to include this example. I should be able to help with some of the propagation efforts as well. Alan __________________________ Alan W.
