To increase the font size of the legend in a Seaborn plot, we can use the fontsize variable and can use it in legend() method argument.
Steps
Create a data frame using Pandas. The keys are number, count, and select.
Plot a bar in Seaborn using barplot() method.
Initialize a variable fontsize to increase the fontsize of the legend.
Use legend() method to place legend on the figure with fontsize in the argument.
To display the figure, use show() method.
Example
import pandas import matplotlib.pylab as plt import seaborn as sns plt.rcParams["figure.figsize"] = [7.00, 3.50] plt.rcParams["figure.autolayout"] = True df = pandas.DataFrame(dict( number=[2, 5, 1, 6, 3], count=[56, 21, 34, 36, 12], select=[29, 13, 17, 21, 8] )) bar_plot1 = sns.barplot(x='number', y='count', data=df, label="count", color="red") bar_plot2 = sns.barplot(x='number', y='select', data=df, label="select", color="green") fontsize = 20 plt.legend(loc="upper right", frameon=True, fontsize=fontsize) plt.show()
