How can I plot multiple lines using Matplotlib?

You can plot multiple lines in Matplotlib by calling the plot() function multiple times before calling show(). Each call to plot() can take different data for the x and y axes.

Can you show me a code example?

Sure! Here's a simple example:

import matplotlib.pyplot as plt

x = [1, 2, 3, 4]
y1 = [1, 4, 9, 16]
y2 = [1, 2, 3, 4]

plt.plot(x, y1, label='y = x^2')
plt.plot(x, y2, label='y = x')
plt.legend()
plt.show()

What if I want to customize the line styles?

You can customize line styles by using additional parameters in the plot() function. For example, you can specify the color, line style, and marker like this:

plt.plot(x, y1, color='red', linestyle='--', marker='o', label='y = x^2')
