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()
我可以得到下图:
在这里,我想将“蓝色”与“红色”的圆圈混合在一起。请注意,混合的结果是brown。
但实际值应该是浅洋红色(下图是使用 default 创建的matplotlib_venn.venn3
):
我怎样才能正确地做到这一点?
