import matplotlib.pyplot as plt

plt.pie(fraction, startangle, wedgeprops, autopct, explode, **)
# example: plt.pie(frac, startangle=90, wedgeprops={'linewidth': 3, 'edgecolor':"white"}, autopct="%1.1f%%", explode=[0.2, 0, 0, 0, 0]
# fraction: total of fraction should be 1
# startangle: startangle
# wedgeprops: edge props
# autopct: show percentage 
# explode: array for explode

plt.legend(labels, bbox_to_anchor, loc)
# labels: labels of fraction
# bbox_to_anchor: relative position to whole of figure
## range => (0, 0) ~ (1, 1) 
# loc: which part of box is set up anchor
## ボックスのどの部分をアンカーに合わせるか
