python seaborn箱线图图例

箱线图的图例可以通过添加`legend=True`参数来实现。例如，使用seaborn库绘制箱线图时，可以在绘图函数中添加`legend=True`来显示图例。以下是一个示例代码：

import seaborn as sns
import matplotlib.pyplot as plt

df = sns.load_dataset('iris')

sns.boxplot(x=df["species"], y=df["sepal_width"], legend=True)
plt.show()

在这个例子中，我们使用seaborn库加载了iris数据集，并使用`boxplot`函数绘制了一个箱线图。通过将`legend=True`作为参数传递给绘图函数，图例将被显示出来。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
