Area plot and stacked plot

The stacked plot owes its name to the fact that it represents the area under a line plot and that several such plots can be stacked on top of one another, giving the feeling of a stack. The stacked plot can be useful when we want to visualize the cumulative effect of multiple variables being plotted on the y axis.

In order to simplify this, think of an area plot as a line plot that shows the area covered by filling it with a color. Enough talk. Let's dive into the code base. First of all, let's define the dataset:

# House loan Mortgage cost per month for a year
houseLoanMortgage = [9000, 9000, 8000, 9000, 
                    8000, 9000, 9000, 9000, 
                    9000, 8000, 9000, 9000]

# Utilities Bills for a year
utilitiesBills = [4218, 4218, 4218, 4218,
                  4218, 4218, 4219, 2218, 
                  3218, 4233, 3000, 3000]
