如何在matplotlib-venn中修改字体大小

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，则文本对象只会存储为out.set_labels和out.subset_labels，因此您可以执行以下操作：

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)

Answer 2

在我的情况下，out.subset_labels的某些值为NoneType。要忽略这个问题，我做了：

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(15)
for x in range(len(out.subset_labels)):
    if out.subset_labels[x] is not None:
        out.subset_labels[x].set_fontsize(15)
