如何将Seaborn FacetGrid中的传奇移到情节之外？

Question

我有以下代码：

g = sns.FacetGrid(df, row="Type", hue="Name", size=3, aspect=3)
g = g.map(sns.plt.plot, "Volume", "Index")
g.add_legend()
sns.plt.show()

结果如下：

我怎样才能把这个传说移到情节之外呢？

Answer 1

可以通过调整绘图大小来执行此操作：

g = sns.FacetGrid(df, row="Type", hue="Name", size=3, aspect=3)
g = g.map(sns.plt.plot, "Volume", "Index")
for ax in g.axes.flat:
    box = ax.get_position()
    ax.set_position([box.x0,box.y0,box.width*0.9,box.height])

sns.plt.legend(loc='center left',bbox_to_anchor=(1,0.5))
sns.plt.show()

示例：

import seaborn as sns

tips = sns.load_dataset('tips')

# more informative values
condition = tips['smoker'] == 'Yes'
tips['smoking_status'] = ''
tips.loc[condition,'smoking_status'] = 'Smoker'
tips.loc[~condition,'smoking_status'] = 'Non-Smoker'

g = sns.FacetGrid(tips,row='sex',hue='smoking_status',size=3,aspect=3)
g = g.map(plt.scatter,'total_bill','tip')
for ax in g.axes.flat:
    box = ax.get_position()
    ax.set_position([box.x0,box.y0,box.width*0.85,box.height])

sns.plt.legend(loc='upper left',bbox_to_anchor=(1,0.5))
sns.plt.show()

结果：
