Stacked Area Graph
Stacked Area Graphs work in the same way as simple Area Graphs do, except for the use of multiple data series that start each point from the point left by the previous data series.
The entire graph represents the total of all the data plotted. Stacked Area Graphs also use area to convey whole numbers, so they do not work for negative values. Overall, they are useful for comparing multiple variables changing over an interval.
