Individually labeled bars for bar graphs

bar-chart, matplotlib, python, x-axis

Solution

Sure is! You just need to reset the tick labels.

EDIT with answer and picture (can be done similarly with `hist`):

x = scipy.arange(4)
y = scipy.array([4,7,6,5])
f = pylab.figure()
ax = f.add_axes([0.1, 0.1, 0.8, 0.8])
ax.bar(x, y, align='center')
ax.set_xticks(x)
ax.set_xticklabels(['Aye', 'Bee', 'Cee', 'Dee'])
f.show()

Problem

I am trying to create bar graphs of letter frequency in Python. I thought the best way to accomplish this would be matplotlib, but I have been unable to decipher the documentation. Is it possible to label the bars of a matplotlib.pyplot.hist plot with one letter per bar, instead of a numerical axis? I think it must be, but I have not used matplotlib before. This is the sort of graph I'm after, rendered as text: ``` | | * | * * | * * * +---------- A B C ```
