Custom Label
You can custom the label of a specific group. In the example below, the label is selected by id using the get_label_by_id() function and then customized by the function set_text().
# Import the library
import matplotlib.pyplot as plt
from matplotlib_venn import venn3
# Custom text labels: change the label of group A
v=venn3(subsets = (10, 8, 22, 6,9,4,2), set_labels = ('Group A', 'Group B', 'Group C'))
v.get_label_by_id('A').set_text('My Favourite group!')
plt.show()
Line Style of Circles
It is possible to change the line style of circles using the venn3_circles() function.
# Import the library
import matplotlib.pyplot as plt
from matplotlib_venn import venn3, venn3_circles
# Line style: can be 'dashed' or 'dotted' for example
v=venn3(subsets = (10, 8, 22, 6,9,4,2), set_labels = ('Group A', 'Group B', 'Group C'))
c=venn3_circles(subsets = (10, 8, 22, 6,9,4,2), linestyle='dashed', linewidth=1, color="grey")
plt.show()
Custom One Group Only
After creating the circles by venn3_circles(), you can select the group you want to customize by its id and use set_lw(), set_ls(), and set_color() functions to make customizations.
# Import the library
import matplotlib.pyplot as plt
from matplotlib_venn import venn3, venn3_circles
# Change one group only
v=venn3(subsets = (10, 8, 22, 6,9,4,2), set_labels = ('Group A', 'Group B', 'Group C'))
c=venn3_circles(subsets = (10, 8, 22, 6,9,4,2), linestyle='dashed', linewidth=1, color="grey")
c[0].set_lw(8.0)
c[0].set_ls('dotted')
c[0].set_color('skyblue')
plt.show()
