Pyplot

Matplotlib Pyplot

  • pyplot is the submodule of matplotlib and comes with most of the functions and features for data visualization.
  • It is imported using the alias plt using this command:
    import matplotlib.pyplot as plt
    

    Let's draw a simple line graph using this setup:

    from matplotlib import pyplot as plt
    
    x-coordiante = [0,1,2,3,4,5,6]
    y-coordinate = [10,12,12,10,14,22,24]
    plt.plot(x-coordinate, y-coordinate)
    plt.show()

     

  • x-coordiante is a variable holding a list of x-values for each point on our line graph.
  • y-coordinate is a variable holding a list of y-values for each point on our line graph.
  • plt is the name we have given to the Matplotlib module we have imported at the top of the code.
  • plt.plot(x-ccordinate, y-coordinate) will create the line graph.
  • plt.show() will actually display the graph.
