[PyX-user] Colors in bar graph

[Carl B. <dr...@gm...>]

Hello,

I almost finished my graphs for publication. The last thing I wanna change
is the colors. I want my graph to be black and white. I have two different
datasets, one is red and the other is blue by default.

I would like to render the red bars black, and the blue ones white.

Here is the code:
____________________________________________________________

from pyx import *

text.set(mode=3D"latex")

mynestedbaraxis =3D graph.axis.bar(defaultsubaxis=3Dgraph.axis.bar(dist=3D0=
))

g =3D graph.graphxy(width=3D8, x=3Dmynestedbaraxis,
y=3Dgraph.axis.lin(min=3D0, max=3D430, title=3D"Number of SAGE tags"),
y2=3Dgraph.axis.lin(min=3D0, max=3D4000000, title=3D"Number of copies/$\mu$=
g of
total RNA"))

g.plot([graph.data.list([["GDX", 422], ["DHT", 71]], xname=3D1, y=3D2),
graph.data.list([["GDX", 3828629, 17760], ["DHT", 1328775, 38357]], xname=
=3D1,
y2=3D2, dy2=3D3)],
[graph.style.barpos(fromvalue=3D0, subnames =3D ["SAGE", "Q\_RT-PCR"]),
graph.style.bar(), graph.style.errorbar()])

g.text(g.width/2, g.height + 0.5, "1-acylglycerol-3-phosphate
O-acyltransferase 2",
[text.halign.center, text.valign.bottom])

g.writeEPSfile("agpat2")
g.writePDFfile("agpat2")

What should I do?

Thank you,
