How to set font size of Matplotlib axis Legend? Last Updated : 05 Nov, 2021 Comments Improve Suggest changes Like Article Like Report Prerequisite: Matplotlib In this article, we will see how to set the font size of matplotlib axis legend using Python. For this, we will use rcParams() methods to increase/decrease the font size. To use this we have to override the matplotlib.rcParams['legend.fontsize'] method. Syntax: matplotlib.rcParams['legend.fontsize'] = font_size_value Example 1: Setting plot size of the legend is 15 Python3 # import required modules import numpy from matplotlib import pyplot import matplotlib # assign value to x axis x_axis = numpy.arange(1, 20, 0.5) # get the value of log10 y_axis_log10 = numpy.exp(x_axis) # plot the graph pyplot.plot(x_axis, y_axis_log10, c="blue", label="exponential") # title of the graph/plot pyplot.title("Exponential Graph Plot") # to set the font size of the legend matplotlib.rcParams['legend.fontsize'] = 15 pyplot.legend(loc='best') pyplot.show() Output: Example 2: Setting the plot size of the legend is 25 Python3 # import required modules import numpy from matplotlib import pyplot import matplotlib # assign value to x axis x_axis = numpy.arange(1, 20, 0.5) # get the value of log10 y_axis_log10 = numpy.exp(x_axis) # plot the graph pyplot.plot(x_axis, y_axis_log10, c="blue", label="exponential") # Title of the graph/ploy pyplot.title("Exponential Graph Plot") # to set the font size of the legend matplotlib.rcParams['legend.fontsize'] = 25 pyplot.legend(loc='best') pyplot.show() Output: Comment More infoAdvertise with us Next Article How to set font size of Matplotlib axis Legend?
