Question

我有下一个情节，但正如你所看到的，它不可能看到直立部分。所以我想知道我能做些什么才能看到整个情节并缩小他的体型。代码来自Stack的另一个用户。

谢谢。

This is the plot

Answer 1

图的大小由fig1 = plt.figure(figsize=(8, 8))决定，所以它的尺寸为8x8英寸。您可以根据需要更改值来缩小尺寸。

图中图的大小由

决定

fig.add_axes([0.1,0.1,0.9,0.9])

此命令表示您添加参数为[left, bottom, width, height]的轴。因此，减少width和height会减小绘图大小。尝试例如fig.add_axes([0.1,0.1,0.7,0.7])或您喜欢的任何其他值。
