我想显示实际值标签而不是甜甜圈图的%age值。以下代码生成了一个非常漂亮的甜甜圈图,但是显示的值是%age的值,而不是实际值。
import matplotlib
import matplotlib.pyplot as plt
import numpy as np
#create labels and values for pie/donut plot
labels = 'ms', 'ps'
sizes = [1851, 2230]
#create center white circle
centre_circle = plt.Circle((0, 0), 0.7, color='white')
#create pie chat
plt.pie(sizes, labels= labels, autopct='%1.1f%%',pctdistance = 1.25,startangle=90,
labeldistance=.8, colors = ["tab:blue", "tab:orange"])
plt.axis('equal')
plt.gca().add_artist(centre_circle)
#Display
plt.show();
我的输出如下所示。
有人可以指导我如何显示实际值(1851、2230),而不是如何在此图中显示其百分比值吗?或者,同时显示百分比年龄及其实际对应值(即1851、45.4%和2230、54.6%)?
答案 0 :(得分:1)
总结我的评论,请尝试以下操作:
import matplotlib.pyplot as plt
labels = 'ms', 'ps'
sizes = 1851, 2230
pcts = [f'{s} {l}\n({s*100/sum(sizes):.2f}%)' for s,l in zip(sizes, labels)]
width = 0.35
_, ax = plt.subplots()
ax.axis('equal')
pie, _ = ax.pie(
sizes,
startangle=90,
labels=pcts,
# labeldistance=.8,
# rotatelabels=True,
colors = ["tab:blue", "tab:orange"]
)
plt.setp(pie, width=width, edgecolor='white')
plt.show()
这是上面代码片段的输出:
