Python matplotlib繪製餅圖

最近用到了matplotlib庫繪製餅圖，之前也沒有做過，所以網上查閱了一些資料

plt.rcParams['font.sans-serif']=['SimHei']   # 用黑體顯示中文

plt.figure(figsize=(14,6))

ax1 = plt.subplot(1,2,1)  #一行兩列第一個圖
shapes1 = ['0-5', '6-10', '11-15', '16-20', '21-25', '26-30', '31-35',
'36-40', '41-45', '46-50', '51-55', '56-60', '61-65', '66-70',
'71-75', '76-80', '81-85', '85-90', '91-95','96-100']
values1 = [ 5,10,9,9,17,12,17,15,12,12,11,19,17,9,13,19,14,18,12,1,]
s1 = pd.Series(values1, index=shapes1)
labels1 = s1.index
sizes1 = s1.values
explode1 = (0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0)

patches, texts, autotexts = ax1.pie(sizes1, explode=explode1, labels=labels1, autopct='%1.2f%%',shadow=False, startangle=170)
ax1.axis('equal') # Equal aspect ratio ensures that pie is drawn as a circle.


ax2 = plt.subplot(1,2,2)  
shapes2 = ['0-5', '6-10', '11-15', '16-20', '21-25', '26-30', '31-35',
'36-40', '41-45', '46-50', '51-55', '56-60', '61-65', '66-70',
'71-75', '76-80', '81-85', '85-90', '91-95','96-100']
values2 = [ 6,11,11,14,14,8,14,20,8,14,17,11,12,10,15,14,22,14,11,0,]
s2 = pd.Series(values2, index=shapes2)
labels2 = s2.index
sizes2 = s2.values
explode2 = (0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0)

patches2, texts2, autotexts2 = ax2.pie(sizes2, explode=explode2, labels=labels2, autopct='%1.2f%%',shadow=False, startangle=170)
ax2.axis('equal') # Equal aspect ratio ensures that pie is drawn as a circle.
plt.suptitle('主場-客場',horizontalalignment='center',fontsize='25')
plt.show()
 

大概解釋下以上引數，shapes是標籤列表；values是數值列表，explode是距離列表，控制每個標籤之間的距離，大家可以自行修改，shadow是餅狀圖陰影，startangle是其實的角度，equal控制產生一個圓。

效果圖如下
