[PyX-user] PyX vs. gnuplot

[Simson L. Garfinkel <simsong@cs...>]

Andre,

I think that you misunderstood my comment. I would much rather use PyX than 
Gnuplot.

But how do I do labeled pen traces within the plot, the way Gnuplot does? I 
can't figure that out.

I think it is not clear to us (at least to me) what you meant with
labeled pen traces. Are you talking about a graph key like the one
in the graphis/piaxis example (see
http://pyx.sourceforge.net/examples/graphs/index.html)

If not, maybe you could post an example output (or a link to it) to the
list.

First, I'm really sorry about my crude comment. Still, we're not
developing gnuplot. Things are not always as easy as gnuplot tries to
make them ...

I guess as well that your question is about graph keys. All you need
to do is to add a key instance to the graph constructor. For example:

    import random
    from pyx import *

    g = graph.graphxy(width=10, key=graph.key.key())
    g.plot([graph.data.list([(j, random.random()) for j in range(20)], x=1, y=2)
            for k in range(3)],
           [graph.style.line()])
    g.writeEPSfile("minimal")
