在 matplotlib 中自动定位文本框 [英] automatically position text box in matplotlib

问题描述

有没有办法像 pyplot.legend() 那样告诉 pyplot.text() 一个位置?

Is there a way of telling pyplot.text() a location like you can with pyplot.legend()?

像legend论证这样的东西会很好:

Something like the legend argument would be excellent:

plt.legend(loc="upper left")

我正在尝试使用字母(例如A"、B")标记具有不同轴的子图.我认为一定有比手动估计位置更好的方法.

I am trying to label subplots with different axes using letters (e.g. "A","B"). I figure there's got to be a better way than manually estimating the position.

谢谢

推荐答案

当我最初发布问题时，我不确定这是否可用，但现在实际上可以使用 loc 参数.下面是一个例子:

I'm not sure if this was available when I originally posted the question but using the loc parameter can now actually be used. Below is an example:

import numpy as np
import matplotlib.pyplot as plt
from matplotlib.offsetbox import AnchoredText

# make some data
x = np.arange(10)
y = x

# set up figure and axes
f, ax = plt.subplots(1,1)

# loc works the same as it does with figures (though best doesn't work)
# pad=5 will increase the size of padding between the border and text
# borderpad=5 will increase the distance between the border and the axes
# frameon=False will remove the box around the text

anchored_text = AnchoredText("Test", loc=2)
ax.plot(x,y)
ax.add_artist(anchored_text)

plt.show()
