我需要使用matplotlib绘制饼图,但是我的DataFrame
有3列,分别是gender
,segment
和total_amount
。
我尝试过使用plt.pie()
参数,但是它只使用x和标签作为数据。我尝试将gender
设置为图例,但看起来不正确。
import matplotlib.pyplot as plt
import pandas as pd
df = pd.DataFrame({'gender': {0: 'Female',
1: 'Female',
2: 'Female',
3: 'Male',
4: 'Male',
5: 'Male'},
'Segment': {0: 'Gold',
1: 'Platinum',
2: 'Silver',
3: 'Gold',
4: 'Platinum',
5: 'Silver'},
'total_amount': {0: 2110045.0,
1: 2369722.0,
2: 1897545.0,
3: 2655970.0,
4: 2096445.0,
5: 2347134.0}})
plt.pie(data = df,x="claim_amount",labels="Segment")
plt.legend(d3.gender)
plt.show()
我想要的结果是一个total_amount
的饼图,其标签为gender
和segment
。如果我能得到该百分比,那将是一个奖励。
答案 0 :(得分:0)
我建议以下内容:
# Data to plot
# Take the information from the segment and label columns and join them into one string
labels = df["Segment"]+ " " + df["gender"].map(str)
# Extract the sizes of the segments
sizes = df["total_amount"]
# Plot with labels and percentage
plt.pie(sizes, labels=labels,autopct='%1.1f%%')
plt.show()
