python - 从 pandas 数据框中制作多个饼图（每行一个）

考虑数据框 df

df = pd.DataFrame(dict(
        Business='Beauty & Spas;Burgers-Restaurants;Pizza;Mexican Restaurants;Modern European-Restaurants;Chineese'.split(';'),
        aniticipation=[0] * 6,
        enjoyment=[6., 1., 6., 33.,150., 19.5],
        sad=[1., 2., 1., 3., 13.5, 0.],
        disgust=[1, 1, 0, 3, 37, 3],
        anger=[1.5, 2., 4., 9., 19., 3.],
        surprise=[3, 0, 0, 2, 12, 1],
        fear=[0, 1, 1, 9, 22, 1],
        trust=[0] * 6
    ))

您可以像这样创建饼图

fig, axes = plt.subplots(2, 3, figsize=(10, 6))

for i, (idx, row) in enumerate(df.set_index('Business').iterrows()):
    ax = axes[i // 3, i % 3]
    row = row[row.gt(row.sum() * .01)]
    ax.pie(row, labels=row.index, startangle=30)
    ax.set_title(idx)

fig.subplots_adjust(wspace=.2)
