[Matplotlib-users] Stacked bar graph.

[Jason C. L. <jas...@gm...>]

hi,

I'm having trouble figuring out how to add a few more layers to a
stacked bar graph.
What I have so far is:

        p1 =3D axes.bar(ind, data['n'], width, color=3D'r')
        p2 =3D axes.bar(ind, data['l'], width, color=3D'y', bottom=3Ddata['=
n'])
        p3 =3D axes.bar(ind, data['m'], width, color=3D'b', bottom=3Ddata['=
l'])
        p4 =3D axes.bar(ind, data['h'], width, color=3D'g', bottom=3Ddata['=
m'])

But I don't think this is correct.  I only get two layers (red and
green).  Does anyone know the proper method?

Thanks,
Jason.
