我試圖並排想象這兩個甜甜圈，但我無法這樣做。 我可以 plot 它們，通常，一個接一個，但是當試圖將它們一起顯示時，結果如下： img 。 我的白色中心圓圈也消失了。 我究竟做錯了什么？

根據此文檔，您需要將餅圖和其他信息（ 例如標題）添加到各個軸：

# -*- coding: utf-8 -*-

# Plot 1
outer_circle = ax.pie(months_sizes, labels=months, colors=months_colors, radius=1.1, startangle=90, frame=True, textprops={'color':"black", 'size': 11},labeldistance=1.05)
inner_circle = ax.pie(weekdays_sizes, labels=weekdays, colors=weekdays_colors, radius=0.8, startangle=90, textprops={'color':"w", 'size': 10})
centre_circle = plt.Circle((0, 0), 0.35, color='white', linewidth=0)
ax.add_artist(centre_circle)
ax.set_title('First Trimester (2020)\nVisual Representation of number of rides per weekday per month', loc='center', fontsize=15, color='black')

# Plot 2
outer_circle_2 = ax_2.pie(months_sizes_2, labels=months_2, colors=months_colors_2, radius=1.1, startangle=90, frame=True, textprops={'color':"black", 'size': 11},labeldistance=1.05)
inner_circle_2 = ax_2.pie(weekdays_sizes_2, labels=weekdays_2, colors=weekdays_colors_2, radius=0.8, startangle=90, textprops={'color':"w", 'size': 10})
centre_circle_2 = plt.Circle((0, 0), 0.35, color='white', linewidth=0)
ax_2.add_artist(centre_circle_2)
ax_2.set_title('Second Trimester (2019)\nVisual Representation of number of rides per weekday per month', loc='center', fontsize=15, color='black')
plt.show()
