準備工作

import matplotlib.pyplot as plt %matplotlib inline import numpy as np import pandas as pd plt.rcParams['font.sans-serif'] = ['SimHei']#用來正常顯示中文標簽 plt.rcParams['axes.unicode_minus'] = False#用來正常顯示負號

餅圖

datas = [33,16,56,90,55] colors = ['red','green','pink','blue','orange'] labels = ['1','2','3','4','5'] plt.pie(datas,colors = colors,labels = labels)

若給的數列和不到1，則會有空白

x = [0.1,0.5,0.2] plt.pie(x)

plt.pie(x,explode=[ , , ])

可以把餅圖的每一塊分離出來

x = [1,5,2] plt.pie(x,explode=[0.2,0,0])

x = [1,5,2] plt.pie(x,explode=[0.2,0.6,0])

plt.pie(x,startangle= )

可以把起始邊旋轉一定的角度

x = [1,5,2] plt.pie(x,startangle=90)

plt.pie(x,labels=[“1”,“2”,“3”],labeldistance=)

可調節標注離中心的距離

plt.pie(x,labels=["1","2","3"],labeldistance=0.5)

出現百分比

plt.pie(x,labels=["1","2","3"],labeldistance=1.2,autopct='%1.1f')

plt.pie(x,labels=["1","2","3"],labeldistance=1.2,autopct='%1.1f%%')

百分比離中心的距離

plt.pie(x,labels=["1","2","3"],labeldistance=1.2,autopct='%1.1f%%',pctdistance=0.2)

餅圖放大

plt.pie(x,labels=["1","2","3"],radius=2)

加邊框

plt.pie(x,labels=["1","2","3"],frame=True)

plt.pie(x,labels=["1","2","3"],frame=True) plt.xlim(-1,1) plt.ylim(-1,1) plt.grid()

設置標簽大小和顏色

plt.pie(x,labels=["a","b","c"],textprops={'fontsize':20,'color':'red'})

環形圖

plt.pie(x,labels=["a","b","c"],textprops={'fontsize':20,'color':'red'}) plt.pie([1],colors='w',radius=0.7)

內嵌環形餅圖

plt.figure(dpi=600) a=[0.4,0.15,0.2,0.1,0.15] b=[0.3,0.25,0.2,0.1,0.15] plt.pie(a) plt.pie(b,radius=0.7)
