要在轴区域外的图形中写入文本，请使用figtext。

不知道这是否回答了你的问题，但你可以把任何文本在一个图与

在我的例子中的所有代码：

import matplotlib.pyplot as plt
from matplotlib_venn import venn3

name_file = "venn_diagram_purpose"

# Make a Basic Venn
plt.close('all')

v = venn3(subsets=(1, 1, 1, 1, 1, 1, 1), 
          set_labels = ('Skills', 
                        'Opportunity',
                        'Interest'))
v.get_label_by_id('111').set_text('Destiny')

plt.show()
plt.savefig(f'{name_file}.png')
