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
Sure is! You just need to reset the tick labels.
EDIT with answer and picture (can be done similarly with
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()
