Hello Benedikt,
I'm not sure, that my solution is the best, but in principle, the following
procedure should work:
- you create the graph with a single key (graphxy.graphxy(
key=graph.key.key() )
- you create 'reference-curves' OUTSIDE the plot-area, which have the
appropriate properties (e.g. solid, dotted,... and red, green,...) with the
respective titles - this will create your key
- in each 'standard' plot-command, you use the title None (title=None) -
with that, the curves do not appear in the key.
So in general, I would try something like:
from pyx import *
col1 = [style.linestyle.solid]
col2 = [style.linestyle.dotted]
row1 = [color.rgb.red]
row2 = [color.rgb.blue]
g = graph.graphxy( width=8,
x=graph.axis.linear(min=0, max=2),
y=graph.axis.linear(min=0, max=2),
key=graph.key.key(pos="br"))
g.plot( graph.data.function("y(x)=20", title=r"**2" ),
[graph.style.line( col1 )] )
g.plot( graph.data.function("y(x)=20", title=r"**4"),
[graph.style.line( col2 )] )
g.plot( graph.data.function("y(x)=20", title=r"x(y)"),
[graph.style.line( row1 )] )
g.plot( graph.data.function("y(x)=20", title=r"y(x)"),
[graph.style.line( row2 )] )
g.plot( graph.data.function("y(x)=x**2", title=None),
[graph.style.line( col1 + row1 )] )
g.plot( graph.data.function("y(x)=x**4", title=None),
[graph.style.line( col2 + row1 )] )
g.plot( graph.data.function("x(y)=y**2", title=None),
[graph.style.line( col1 + row2 )] )
g.plot( graph.data.function("x(y)=y**4", title=None),
[graph.style.line( col2 + row2 )] )
g.writeEPSfile("test")
HTH,
Axel
