python - python pandas 中按组分组的子图

Question

我想为以下数据制作子图。我平均并分组在一起。 我想按国家对x轴资源和y轴平均值进行子统计。

country       resource     average
india         water         76
india         soil          45
india         tree          60
US            water         45
US            soil          70
US            tree          85
Germany       water         76
Germany       soil          65
Germany       water         56

Grouped = df.groupby(['country','resource'])['TTR in minutes'].agg({'average': 'mean'}).reset_index()

我尝试过，但无法在子图中绘制

Answer 1

g = df.groupby('country')

fig, axes = plt.subplots(g.ngroups, sharex=True, figsize=(8, 6))

for i, (country, d) in enumerate(g):
    ax = d.plot.bar(x='resource', y='average', ax=axes[i], title=country)
    ax.legend().remove()

fig.tight_layout()
