问题描述
因此,我使用此代码用python创建了一个甜甜圈图(此甜甜圈图启发了食谱):
So I using this code to create a donut chart with python (inspired in this Donut plot recipe):
def make_pie(sizes, text,colors,labels):
import matplotlib.pyplot as plt
import numpy as np
col = [[i/255. for i in c] for c in colors]
fig, ax = plt.subplots()
ax.axis('equal')
width = 0.35
kwargs = dict(colors=col, startangle=180)
outside, _ = ax.pie(sizes, radius=1, pctdistance=1-width/2,labels=labels,**kwargs)
plt.setp( outside, width=width, edgecolor='white')
kwargs = dict(size=20, fontweight='bold', va='center')
ax.text(0, 0, text, ha='center', **kwargs)
plt.show()
c1 = (226,33,7)
c2 = (60,121,189)
make_pie([257,90], "Gender (AR)",[c1,c2],['M','F'])
其结果是:
我的问题是,现在我想要各自的百分比.为此,我只是添加了参数:
My problem is that now I want the respective percentages. For that I was simply adding the argument:
autopct='%1.1f%%'
像这样:
kwargs = dict(colors=col, startangle=180,autopct='%1.1f%%')
但这会导致以下错误:
Traceback (most recent call last):
File "draw.py", line 30, in <module>
make_pie([257,90], "Gender (AR)",[c1,c2],['M','F'])
File "draw.py", line 13, in make_pie
outside, _ = ax.pie(sizes, radius=1, pctdistance=1-width/2,labels=labels,**kwargs)
ValueError: too many values to unpack
那么,我在做什么错了?
So, what am I doing wrong?
推荐答案
来自文档字符串:
If *autopct* is not *None*, return the tuple (*patches*,
*texts*, *autotexts*), where *patches* and *texts* are as
above, and *autotexts* is a list of
:class:`~matplotlib.text.Text` instances for the numeric
labels.
因此,如果要使用autopct
解压缩pie()
的结果,则需要3个值:
So if you want to unpack the result of pie()
using autopct
you need 3 values:
kwargs = dict(colors=col, startangle=180, autopct='%1.1f%%')
outside, _, _ = ax.pie(sizes, radius=1, pctdistance=1-width/2,
labels=labels,**kwargs)
或者在不打开包装的情况下,它可能会更健壮,因此无论是否使用autopct
,它都可以使用:
Or maybe it will be more robust without unpacking so it works with or without autopct
:
outside = ax.pie(sizes, radius=1, pctdistance=1-width/2,
labels=labels,**kwargs)[0]
