删除Seaborn barplot图例标题 [英] Remove Seaborn barplot legend title

问题描述

我使用seaborn来绘制分组的条形图，如

I use seaborn to plot a grouped bar plot as in https://seaborn.pydata.org/examples/factorplot_bars.html

Giving me: https://seaborn.pydata.org/_images/factorplot_bars.png

there is a title (sex) on the legend which I would like to remove.

How could I achieve that?

解决方案

This may be a hacky solution but it works: if you tell Seaborn to leave it off at the time of plotting and then add it back it doesn't have the legend title:

g = sns.factorplot(x='Age Group',y='ED',hue='Became Member',col='Coverage Type',
                   col_wrap=3,data=gdf,kind='bar',ci=None,legend=False,palette='muted')
#                                                         ^^^^^^^^^^^^
plt.suptitle('ED Visit Rate per 1,000 Members per Year',size=16)
plt.legend(loc='best')
plt.subplots_adjust(top=.925)
plt.show()

Example result:
