[FIXED] Pie chart enclosed with a black line (rectangle)

Issue

Below you can see my data and facet plot in matplotlib.

import pandas as pd
import numpy as np
pd.set_option('max_columns', None)
import matplotlib.pyplot as plt
import matplotlib as mpl

# Data

data = {
         'type_sale': ['g_1','g_2','g_3','g_4','g_5','g_6','g_7','g_8','g_9','g_10'],
         'open':[70,20,24,150,80,90,60,90,20,20],
         'closed':[30,14,20,10,20,40,10,10,10,10],
        }

df = pd.DataFrame(data, columns = ['type_sale',
                                   'open',
                                   'closed',
                                   ])

data1 = {
         'type_sale': [ 'open','closed'],
         'structure':[70,30],
                 }

df1 = pd.DataFrame(data1, columns = ['type_sale',
                                   'structure',
                                   ])



# Ploting
labels = ['open','closed']

fig, axs = plt.subplots(2,2, figsize=(10,8))
plt.subplots_adjust(wspace=0.2, hspace=0.6)
df1.plot(x='type_sale', y='structure',labels=labels,autopct='%1.1f%%',kind='pie', title='Stacked Bar Graph by dataframe',ax=axs[0,0])
df.plot(x='type_sale', kind='bar', stacked=True, title='Stacked Bar Graph by dataframe', ax=axs[0,1])
df.plot(x='type_sale', kind='bar', stacked=True, title='Stacked Bar Graph by dataframe',ax=axs[1,0])
df.plot(x='type_sale', kind='bar', stacked=True,title='Stacked Bar Graph by dataframe', ax=axs[1,1])

plt.suptitle(t='Stacked Bar Graph by dataframe', fontsize=16)
plt.show()

If you compare the first pie plot with others, you can spot a big difference. Namely, the first pie plot is not enclosed with a black line (rectangle), while the other is enclosed.

So can anybody help me with how to solve this problem?

Solution

After playing around myself, it seems that this is working, but I think the pie gets stretched, which doesn't look that good.

EDIT found a better solution with set_adjustable

also two options how you create the piechart, the frame and ticks differ in a bit.

# 1
axs[0,0].pie(df1['structure'],labels=labels,autopct='%1.1f%%',frame=True,radius=10) 
axs[0,0].set_title('Stacked Bar Graph by dataframe')

# 2
df1.plot(x='type_sale', y='structure',labels=labels,autopct='%1.1f%%',kind='pie', title='Stacked Bar Graph by dataframe',ax=axs[0,0])

axs[0,0].set_frame_on(True)
axs[0,0].set_adjustable('datalim')
