如何改变 Matplotlib 图中标题的字体大小？
原文:https://www.geesforgeks.org/如何更改 matplotlib-figure 中标题的字体大小/
在本文中，我们将讨论如何使用matplotlib模块更改图中标题的字体大小。
由于我们使用matplotlib.pyplot.title()方法为一个图分配一个标题，因此为了更改字体大小，我们将使用 matplotlib 模块中pyplot.title()方法的 fontsize 参数。**
下面是一些描述如何在 matplotlib 图中改变标题字体大小的程序:
*例 1:*
蟒蛇 3
**# importing module
import matplotlib.pyplot as plt
# assigning x and y coordinates
x = [-5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5]
y = []
for i in range(len(x)):
y.append(max(0, x[i]))
# depicting the visualization
plt.plot(x, y, color='green')
plt.xlabel('x')
plt.ylabel('y')
# displaying the title
plt.title("ReLU Function",
fontsize = 40)**
*输出:*
*例 2:*
蟒蛇 3
**# importing modules
from matplotlib import pyplot as plt
# assigning x and y coordinates
foodPreference = ['Vegetarian', 'Non Vegetarian',
'Vegan', 'Eggitarian']
consumers = [30, 100, 10, 60]
# depicting the visualization
fig = plt.figure()
ax = fig.add_axes([0, 0, 1, 1])
ax.axis('equal')
ax.pie(consumers, labels = foodPreference,
autopct='%1.2f%%')
# displaying the title
plt.title("Society Food Preference",
fontsize = 10)**
*输出:*
*例 3:*
蟒蛇 3
**# importing modules
from matplotlib import pyplot
import numpy
# assigning time values of the signal
# initial time period, final time period
# and phase angle
signalTime = numpy.arange(0, 100, 0.5)
# getting the amplitude of the signal
signalAmplitude = numpy.sin(signalTime)
# depicting the visualization
pyplot.plot(signalTime, signalAmplitude,
color = 'green')
pyplot.xlabel('Time')
pyplot.ylabel('Amplitude')
# displaying the title
pyplot.title("Signal",
fontsize = 30)**
*输出:*
