用下面的代碼:準確的色彩混合
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()
我可以得到如下圖所示:
在這裏,我想融入圈子的「藍」與'紅'。 請注意,混合的結果是棕色。
但應該是淡品紅(下圖使用的是默認matplotlib_venn.venn3
創建的)實際值:
我怎樣才能做到這一點是否正確?
