I seem to experiencing a bug when doing bar charts and display a legend.
I'm calling the figlegend properly I think with a reference to the objects
returned from the bar() calls. The problem is both color patches in the
legend appear orange. Any ideas?
I'm using matplotlib0.87.7, Python2.5, and Numpy 1.0.

xlabel("Hour of Day")
figtext(0.5, 0.96, "Compute Server Loading", horizontalalignment='center')
figlegend( (bar_wait, bar_cpu), ("Wait", "CPU"), "upper right", shadow=True)
savefig('fdxcn_plot', dpi=100)
nodes = "fdxcn01 fdxcn02".split()
cpu = [0,0,0,0,0,3,12,14,18,29,38,49,61,32,19,16,9,7,3,2,0,0,9,1]
t = []
wait = []
for i in range(len(cpu)):
t.append(i + 0.25)
wait.append(cpu[i]/3.0)
plot9(nodes, t, cpu, wait)
