使用 matplotlib 中的许多子图改进子图大小/间距 [英] Improve subplot size/spacing with many subplots in matplotlib

问题描述

非常类似于这个问题但不同的是我的身材可以尽可能大.

Very similar to this question but with the difference that my figure can be as large as it needs to be.

我需要在 matplotlib 中生成一大堆垂直堆叠的图.结果将使用 figsave 保存并在网页上查看，所以我不关心最终图像有多高，只要子图间隔开所以它们不重叠.

I need to generate a whole bunch of vertically-stacked plots in matplotlib. The result will be saved using figsave and viewed on a webpage, so I don't care how tall the final image is as long as the subplots are spaced so they don't overlap.

无论我允许图形有多大，子图似乎总是重叠.

No matter how big I allow the figure to be, the subplots always seem to overlap.

我的代码目前看起来像

import matplotlib.pyplot as plt
import my_other_module

titles, x_lists, y_lists = my_other_module.get_data()

fig = plt.figure(figsize=(10,60))
for i, y_list in enumerate(y_lists):
    plt.subplot(len(titles), 1, i)
    plt.xlabel("Some X label")
    plt.ylabel("Some Y label")
    plt.title(titles[i])
    plt.plot(x_lists[i],y_list)
fig.savefig('out.png', dpi=100)

推荐答案

尝试使用 plt.tight_layout

举个简单的例子:

import matplotlib.pyplot as plt

fig, axes = plt.subplots(nrows=4, ncols=4)
fig.tight_layout() # Or equivalently,  "plt.tight_layout()"

plt.show()

Without Tight Layout

布局紧凑
