使用 setp 在 matplotlib 紧密布局中包装长 y 标签 [英] Wrapping long y labels in matplotlib tight layout using setp
问题描述
我一直试图在我的代码中为长标签包装文本.我尝试了之前建议的 textwrap 方法这里,但我的代码通过使用 pyplot.setp()
方法从 csv 导入的数组.否则我使用 tight_layout()
进行格式化.
I've been trying to wrap text for long labels in my code. I tried the textwrap method suggested earlier here, but my code defines yticklabels through an array imported from a csv using the pyplot.setp()
method. I'm using tight_layout()
for the formatting otherwise.
所以问题是 - 有没有办法轻松地将非常长的 y 标签包装到换行符?
So the question is - is there a way to wrap the really long y labels to newlines easily?
这是一些我想要修复的示例代码:
Here is some sample code that I'd like a fix for:
import numpy as np
import matplotlib.pyplot as plt
labels=('Really really really really really really long label 1', 'Really really really really really really long label 2', 'Really really really really really really long label 3')
values=(30,50,40)
fig = plt.figure()
ax=fig.add_subplot(111)
plt.ylim((0,40))
for i in np.arange(3):
plt.barh(15*i, values[i])
plt.yticks(15*np.arange(3))
plt.setp(ax.set_yticklabels(labels))
plt.tight_layout()
plt.show()
这绘制了这样的图我希望标签在固定宽度后转到换行符.有什么想法吗?
This plots something like this I'd like the labels to go to newlines after a fixed width. Any ideas?
推荐答案
我曾尝试在标签上使用 textwrap
并且对我有用.
I have tried using textwrap
on the labels and it works for me.
from textwrap import wrap
labels=['Really really really really really really long label 1',
'Really really really really really really long label 2',
'Really really really really really really long label 3']
labels = [ '
'.join(wrap(l, 20)) for l in labels ]
在你的代码中插入这个给我们:
