我可以在matplotlib支持的AItoff投影中反向Xaxis吗？ （这不是重复的。）

Question

我想在我的Python脚本中扭转我的AiToff投影的Xaxis。这是一个示例

import numpy as np
import matplotlib.pyplot as plt
X=[-1,0,1,2]
Y=[0,1,0,1]
plt.figure()
plt.subplot(111,projection="aitoff")
plt.grid(True)
plt.gca().invert_xaxis()
plt.scatter(X,Y)
plt.show()

plt.gca（）。invert_xaxis（）将显示错误。

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/hea/.local/lib/python3.10/site-packages/matplotlib/axes/_base.py", line 3525, in invert_xaxis
    self.xaxis.set_inverted(not self.xaxis.get_inverted())
  File "/home/hea/.local/lib/python3.10/site-packages/matplotlib/axis.py", line 2243, in set_inverted
    self.axes.set_xlim(sorted((a, b), reverse=bool(inverted)), auto=None)
  File "/home/hea/.local/lib/python3.10/site-packages/matplotlib/projections/geo.py", line 151, in set_xlim
    raise TypeError("Changing axes limits of a geographic projection is "
TypeError: Changing axes limits of a geographic projection is not supported.  Please consider using Cartopy.

如果我删除plt.gca（）。invert_xaxis（），它将正常工作。有什么办法可以修复它？

我有一个解决方法，但是需要一些特殊的plt.plt.pause s才能使其正常工作（如果省略了这些暂停，则在操纵后根本没有显示XTICKS）：

而不是反转X轴，尝试翻转X坐标和Xticklabels：

import numpy as np
import matplotlib.pyplot as plt
X=[-1,0,1,2]
Y=[0,1,0,1]
plt.figure()
plt.subplot(111,projection="aitoff")
plt.grid(True)

X = -np.array(X)  # flip X coordinates
plt.scatter(X,Y)

plt.pause(0.5)  # without theses pauses the ticks are not displayed at all, not sure why
ax = plt.gca()
ax.set_xticklabels(ax.get_xticklabels()[::-1])  # flip xticklabels
plt.pause(0.5) # without theses pauses the ticks are not displayed at all, not sure why
plt.show()
