MatplotlibServer Side ProgrammingProgramming

To increase plt.title font size, we can initialize a variable fontsize and can use it in the title() method's argument.

Steps

  • Create x and y data points using numpy.

  • Use subtitle() method to place the title at the center.

  • Plot the data points, x and y.

  • Set the title with a specified fontsize.

  • To display the figure, use show() method.

Example

import numpy as np
from matplotlib import pyplot as plt
plt.rcParams["figure.figsize"] = [7.00, 3.50]
plt.rcParams["figure.autolayout"] = True
x = np.linspace(-1, 1, 10)
y = x ** 2
fontsize = 12
plt.suptitle("Quadratic Equation", fontsize=fontsize)
plt.plot(x, y)
plt.title("y=x$^{2}$", fontdict={'fontsize': fontsize})
plt.show()

Output
