Let's start with something simple: adding a title to a graphic.
The following code will add a title to the figure:
import numpy as np import matplotlib.pyplot as plt X = np.linspace(-4, 4, 1024) Y = .25 * (X + 4.) * (X + 1.) * (X - 2.) plt.title('A polynomial') plt.plot(X, Y, c = 'k') plt.show()
Here, we render a simple curve and add a title to the figure, which appears at the top of the figure:
It's simply done with the
pyplot.title()function, which takes one string as a parameter and sets the title for the whole figure.
