python - 如何修改matplotlib-venn中的字体大小

Question

我有以下维恩图:

from matplotlib import pyplot as plt
from matplotlib_venn import venn3, venn3_circles
set1 = set(['A', 'B', 'C', 'D'])
set2 = set(['B', 'C', 'D', 'E'])
set3 = set(['C', 'D',' E', 'F', 'G'])

venn3([set1, set2, set3], ('Set1', 'Set2', 'Set3'))

看起来像这样:

如何控制绘图的字体大小？我想增加它。

Answer 1

如果 out 是 venn3() 返回的对象，文本对象只是存储为 out.set_labels 和 out .subset_labels，所以你可以这样做:

from matplotlib import pyplot as plt
from matplotlib_venn import venn3, venn3_circles
set1 = set(['A', 'B', 'C', 'D'])
set2 = set(['B', 'C', 'D', 'E'])
set3 = set(['C', 'D',' E', 'F', 'G'])

out = venn3([set1, set2, set3], ('Set1', 'Set2', 'Set3'))
for text in out.set_labels:
    text.set_fontsize(14)
for text in out.subset_labels:
    text.set_fontsize(16)
