How to increase the font size of the legend in my Seaborn plot?
提问by user3115933
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.
我有以下代码来创建 Seaborn 带状图。我很难弄清楚如何增加图中出现的图例的字体大小。
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')
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?
我的 x 轴和 y 轴标签字体大小没问题，但我的图中图例的字体大小很小。如何改变它？

Use matplotlib function setpaccording to this example:
setp根据此示例使用 matplotlib 函数：
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()
Another way is to change font_scaleof all graph with plotting_context:

另一种方法是更改font_scale所有图形plotting_context：http:

There is a much easier way to do this today, simply set up your figure and then call
今天有一个更简单的方法来做到这一点，只需设置你的数字，然后调用
plt.legend(fontsize='x-large', title_fontsize='40')

Might depend on the version of matplotlib you're using. I'm using 2.2.3 and it has the fontsizeparameter but not the title_fontsize.
可能取决于您使用的 matplotlib 版本。我使用的是 2.2.3，它有fontsize参数但没有title_fontsize.
