如何在 matplotlib/pylab 图表中水平打印 Y 轴标签?
问题描述
我正在使用 matplotlib/pylab Python 模块创建非常简单的图表.标记 Y 轴的字母y"在其一侧.如果标签较长(例如单词)，您会期望这样做，以免将图形的外部向左延伸太多.但是对于一个字母的标签，这是没有意义的，标签应该是直立的.我的搜索是空白的.如何水平打印y"?
I'm creating very simple charts with matplotlib / pylab Python module. The letter "y" that labels the Y axis is on its side. You would expect this if the label was longer, such as a word, so as not to extend the outside of the graph to the left too much. But for a one letter label, this doesn't make sense, the label should be upright. My searches have come up blank. How can I print the "y" horizontally?
解决方案
很简单.绘制标签后，您可以简单地更改旋转:
It is very simple. After plotting the label, you can simply change the rotation:
from matplotlib import pyplot as plt
plt.ion()
plt.plot([1,2,3])
h = plt.ylabel('y')
h.set_rotation(0)
plt.draw()
或者，您可以将旋转作为参数传递，即
Alternatively, you can pass the rotation as an argument, i.e
plt.ylabel('y',rotation=0)
