Importing matplotlib and pyplot
Pyplot is a collection of functions in the popular visualization package Matplotlib. Its functions manipulate elements of a figure, such as creating a figure, creating a plotting area, plotting lines, adding plot labels, etc. Let's use the plot()
function from pyplot to create a dashed line graph showing the growth of a company's stock. Remember, you can change the color of the line by adding the argument color
and the linestyle by adding the argument linestyle
.
Two lists, days
(representing the days since the company became public), and prices
(representing the price of the stock corresponding to that day) are available in your workspace.
