如何设置 Matplotlib 轴图例的字体大小？

先决条件:T2【马特洛特利
在本文中，我们将看到如何使用 Python 设置 matplotlib 轴图例的字体大小。为此，我们将使用 rcParams()方法来增加/减少字体大小。为此，我们必须重写 matplotlib.rcparams[' legend.font size ']方法。
语法:matplotlib.rcparams[' legend.fontsize ']= font_size_value
示例 1:将图例的地块大小设置为 15
蟒蛇 3
# 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()
输出:
例 2:将图例的地块大小设置为 25

# 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()
输出:
