使用以下代码:
from matplotlib import pyplot as plt
from matplotlib_venn import venn2
from collections import OrderedDict
named_sets = {'x1': set(['foo','foo','bar',"pax"]), "x3" : set(['foo','qux','bar',"zoo"])}
od = OrderedDict(sorted(named_sets.iteritems()))
circlenm = ()
circlels = []
for k,v in od.iteritems():
circlenm = circlenm + (k,)
circlels.append(v)
c = venn2(subsets = circlels,set_labels = circlenm)
c.get_patch_by_id('10').set_color('red')
c.get_patch_by_id('01').set_color('blue')
c.get_patch_by_id('10').set_edgecolor('none')
c.get_patch_by_id('01').set_edgecolor('none')
c.get_patch_by_id('10').set_alpha(0.4)
c.get_patch_by_id('01').set_alpha(0.4)
plt.show()我可以得到以下数字:

在这里,我想把“蓝色”和“红色”的圆圈混合起来。注意,混合的结果是brown。
但是实际值应该是light洋红(下面的图是使用默认matplotlib_venn.venn3创建的):

我如何才能正确地做到这一点?

添加这3行以设置交集的颜色和显示属性:
c.get_patch_by_id('11').set_color('magenta')
c.get_patch_by_id('11').set_edgecolor('none')
c.get_patch_by_id('11').set_alpha(0.4)如果您想要一个确切的颜色,那么您可以这样设置:
c.get_patch_by_id('11').set_color('#e098e1')修补程序id是一个位掩码,显示该区域在内部的哪个圆圈。
