I share Tufte's opinion that you should avoid chart-junk -- stuff
designed to make charts look sexier that don't add information
context. matplotlib can do it (but doesn't go out of it's way to make
it easy). Eg,
from pylab import figure, show, nx, cm
def gbar(ax, x, y, width=0.5, bottom=0):
X = [[.6, .6],[.7,.7]]
for left,top in zip(x, y):
right = left+width
ax.imshow(X, interpolation='bicubic', cmap=cm.Blues,
extent=(left, right, bottom, top), alpha=1)
fig = figure()
xmin, xmax = xlim = 0,10
ymin, ymax = ylim = 0,1
ax = fig.add_subplot(111, xlim=xlim, ylim=ylim,
autoscale_on=False)
X = [[.6, .6],[.7,.7]]
ax.imshow(X, interpolation='bicubic', cmap=cm.copper,
extent=(xmin, xmax, ymin, ymax), alpha=1)
N = 10
x = nx.arange(N)+0.25
y = nx.mlab.rand(N)
gbar(ax, x, y, width=0.7)
ax.set_aspect('normal')
show()
