Python 不保存极坐标图

阿鲁纳

我一直在尝试导出一个绘图，以便我可以在演示文稿中使用它，无论出于何种原因，python 只导出一个白色方块。我可以使用 Spyder 的内置绘图选项卡保存绘图，但我想稍后使用代码来进一步操作它。Spyder 按原样保存图片没有问题。这就是图像应该看起来的样子。我看过有类似问题的人，但我找到的解决方案都没有奏效。提前为长列表感到抱歉，它们来自我无法共享的文本文件，我需要共享情节信息，以便您可以看到我正在处理的内容。

fig.add_axes第一个论点rect是

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

因此，您需要将该行更改为，例如，

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