python中堆叠百分比条形图的问题

Question

我在尝试了一切之后才写下这个问题。我正在尝试使用this code创建堆叠百分比条形图。我有以下建议：

         name   first   second  third   fourth
0   C.McCaffrey 218.8   152.7   57.1    17.8

21  T.Cohen     56.2    59.9    30.4    30.4
22  M.Mack      91.2    62.7    5.0 0.7
23  M.Gordon    101.5   31.1    16.9    7.1
24  R.Jones     96.0    47.2    11.5    0.0

29  J.Williams  60.4    57.6    25.3    3.0

我使用的是示例中的精确代码

fig, ax = plt.subplots(figsize=(15,15))
plt.style.use('fivethirtyeight')

r = [0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29]
# From raw value to percentage
totals = [i+j+k+l for i,j,k,l in zip(pivot['first'], pivot['second'], pivot['third'], pivot['fourth'])]
firstBars = [i / j * 100 for i,j in zip(pivot['first'], totals)]
secondBars = [i / j * 100 for i,j in zip(pivot['second'], totals)]
thirdBars = [i / j * 100 for i,j in zip(pivot['third'], totals)]
fourthBars = [i / j * 100 for i,j in zip(pivot['fourth'], totals)]
 
# plot
barWidth = 0.85
names = ('J.Jacobs',
 'C.Hyde',
 'T.Gurley',
 'M.Gordon',
 'R.Jones',
 'D.Henry',
 'N.Chubb',
 'M.Mack',
 'A.Ekeler',
 'J.Mixon',
 'L.Murray',
 'P.Lindsay',
 'D.Freeman',
 'K.Drake',
 'D.Singletary',
 'A.Jones',
 'E.Elliott',
 'C.McCaffrey',
 'L.Fournette',
 'A.Kamara',
 'M.Ingram',
 'M.Sanders',
 'L.Bell',
 'D.Montgomery',
 'J.Williams',
 'S.Barkley',
 'C.Carson',
 'D.Cook',
 'T.Cohen',
 'J.White')

plt.bar(r, firstBars, color='#D63E4F', edgecolor='white',width=barWidth)

plt.bar(r, secondBars, bottom=firstBars, color='#FCAE61', edgecolor='white',width=barWidth)

plt.bar(r, thirdBars, bottom=firstBars, color='#65C2A5', edgecolor='white',width=barWidth)

plt.bar(r, fourthBars, bottom=firstBars, color='#3387BD', edgecolor='white',width=barWidth)



plt.xticks(r, names)

plt.grid(zorder=0,alpha=.4)

但是我的图表中的条加起来不是100，如下所示。还有，为什么这些条不符合我绘制它们的顺序？还有，为什么J.White（显示的最后一个条）只有first和second的数据，而在数据框中他显然有third的数据？我试着调试我能调试的一切，现在我只是感到沮丧。我有确切的密码，怎么了？另外，我想把它做成一个水平条形图，但是plt.barh()不起作用。我非常感谢你的帮助，我现在完全不知所措

Answer 1

你是说：

s = df.set_index('name')
s = s.div(s.sum(1),axis='rows')
s.plot.bar(stacked=True)

输出：

对于水平条，只需将plot.bar更改为plot.barh：

s.plot.barh(stacked=True)

输出：
