多个饼图的通用图例
Common legend for multiple pie chart plots
如何在图表底部为两个图表设置通用图例。我尝试使用 fig.legend 但不知道如何正确书写。谢谢!!
import pandas as pd
# Intialise data to Dicts of series.
d = {'Oil' : pd.Series([1.0, 17.0, 0.3, 81.7],
index =['Others', 'Commercial', 'Industrial', 'Domestic']),
'Coal' : pd.Series([3, 34.8, 38.6, 23.6],
index =['Others', 'Commercial', 'Industrial', 'Domestic'])}
# creates Dataframe.
df = pd.DataFrame(d)
fig, axes = plt.subplots(1,2, figsize=(15,4.5))
fig.suptitle('Customers Profile and Energy Sold per Sector', fontweight='bold', fontsize=20)
for ax, col in zip(axes, df.columns):
ax.pie(df[col], wedgeprops=dict(linewidth = 3, edgecolor = 'white'), colors=['#EE8434','#C95D63', '#AE8799','#717EC3'],startangle=90, autopct='%.2f%%', pctdistance=1.2)
#fig.legend(ax, df.index, 'upper left')

fig.legend(chart[0], df.index, 'lower center')
