Plotting a line using Matplotlib

In this recipe, we will learn to plot a line using Matplotlib that passes through specific x and y coordinates.

Matplotlib is a Python 2D plotting library that makes the complicated task of plotting lines, histograms, bar charts, and so on quite easy. This library not only plots, but also provides an API that enables the embedding of plots in applications too.

Getting ready

You can install Matplotlib by using the following statement:

pip install matplotlib

Let's assume that we want to plot a line that uses the following sets of x and y coordinates:

x=10, y=20
x=20, y=40
x=30, y=60

On the x axis, the value of x begins from 0 and increases towards the right and on the y axis, the value of y is 0 at the bottom and increases as we move up. Because the last pair of coordinates is 30, 60, the graph will have the maximum x value of 30 and the maximum y value of 60.

The following methods of matplotlib.pyplot will be used in this recipe:
