如何增加Seaborn图中图例的字体大小? [英] How to increase the font size of the legend in my Seaborn plot?

问题描述

我有以下代码来创建Seaborn带状图.我很难弄清楚如何增加剧情中出现的图例的字体大小.

I have the following codes to create a Seaborn strip plot. I am having a hard time figuring out how to increase the font size of the legend appearing in the plot.

g=sns.stripplot(x="Market", y="Rate", hue="Group",data=myBenchmarkData, jitter=True, size=12, alpha=0.5)
g.axes.set_title("4* Rate Market and by Hotel Groups for Year 2016",fontsize=25)
g.set_xlabel("Market",fontsize=20)
g.set_ylabel("Rate (in EUR)",fontsize=20)
g.tick_params(labelsize=15)
plt.savefig ('benchmark1.png')

我对我的x轴和y轴标签的字体大小没问题，但是我的情节中图例的字体大小很小.如何更改?

I am OK with my x-axis and y-axis labels font size but the font size of the legend in my plot is small. How to change it?

推荐答案

根据此示例使用matplotlib函数setp:

Use matplotlib function setp according to this example:

import seaborn as sns
import matplotlib.pylab as plt
sns.set_style("whitegrid")
tips = sns.load_dataset("tips")

ax = sns.stripplot(x="sex", y="total_bill", hue="day", data=tips, jitter=True)
plt.setp(ax.get_legend().get_texts(), fontsize='22') # for legend text
plt.setp(ax.get_legend().get_title(), fontsize='32') # for legend title

plt.show()

另一种方法是使用plotting_context更改所有图形的font_scale: http://seaborn.pydata.org/genic/seaborn.plotting_context.html

Another way is to change font_scale of all graph with plotting_context: http://seaborn.pydata.org/generated/seaborn.plotting_context.html
