如何修改matplotlib - 維恩的字體大小

Question

我有以下的維恩圖：

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')) 

，看起來像這樣：

如何控制的字體大小情節？ 我想增加它。

Answer 1

如果out是venn3()返回的對象，該文本對象只是存儲爲out.set_labels和out.subset_labels，所以你可以做：

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)
