Area
Documentation
Area series can be used to clearly emphasize change in values. In this example, you can switch between the area, stacked area and full-stacked area series types. Stacked area series help visualize multiple series and compare the manner in which each series contributes to the total aggregate value for specific arguments. Full-stacked area series help compare the percentage value of multiple area series for each argument.
