Python不保存极坐标条形图

Question

我一直在尝试导出一个图，以便我可以在演示文稿中使用它，但不知出于什么原因，python只导出一个白色的正方形。我可以使用Spyder内置的plot选项卡保存情节，但我希望稍后使用代码进一步操作它。Spyder保存图片是没有问题的。这就是图像的样子。我看过有类似问题的人，但我找到的解决方案都不起作用。提前为长列表道歉，它们来自一个文本文件，我不能分享，我需要分享情节信息，这样你就可以看到我在处理什么。

Answer 1

fig.add_axes第一个参数是rect，其中

rect: sequence of float
The dimensions [left, bottom, width, height] of the new Axes. All quantities are in fractions of figure width and height.

那么，你需要把这行改成，例如，

ax = fig.add_axes([0, 0, 1, 1], polar=True)
