[英]Individually labeled bars for bar graphs in matplotlib / Python
I am trying to create bar graphs of letter frequency in Python. 我试图在Python中创建字母频率的条形图。 I thought the best way to accomplish this would be matplotlib, but I have been unable to decipher the documentation. 我认为实现这一目标的最佳方法是matplotlib,但我无法破译文档。 Is it possible to label the bars of a matplotlib.pyplot.hist plot with one letter per bar, instead of a numerical axis? 是否可以标记matplotlib.pyplot.hist图的条形图,每个条形码只有一个字母,而不是数字轴? I think it must be, but I have not used matplotlib before. 我认为一定是,但我之前没有使用过matplotlib。
This is the sort of graph I'm after, rendered as text: 这是我之后的图形,呈现为文本:

Sure is! 当然是! You just need to reset the tick labels. 您只需重置刻度标签即可。
EDIT with answer and picture (can be done similarly with hist
): 用答案和图片编辑(可以用hist
进行类似):
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()
