How can I generate more colors on pie chart matplotlib
matplotlib, pie-chart, python
Solution
You need `colors` argument, beside that you can use some color maps from `cm`.
import matplotlib.pyplot as plt
from matplotlib import cm
import numpy as np
a=np.random.random(40)
cs=cm.Set1(np.arange(40)/40.)
f=plt.figure()
ax=f.add_subplot(111, aspect='equal')
p=plt.pie(a, colors=cs)
plt.show()
Beside using colormaps, also consider using `.set_color_cycle()` method. See this post: plotting different colors in matplotlib
Problem
I am having more then 40 items to show in my chart. I have only 10 colours that repeatedly are shown on the chart. How can I generate more colors. ``` plt.pie(f,labels=labels,autopct='%1.1f%%', startangle=90,shadow=True) ``` I should add "color=colors" where colors is generated infinitely ?
