Area

API Reference
Area chart series types can be used to clearly emphasize change in values displayed within a chart. In this example, you can switch between a area, stackedArea and fullStackedArea series types. The stacked series types help visualize multiple series and compare the manner in which each series contributes to the total aggregate value for specific arguments. The Full Stacked Area chart series helps compare the percentage value of multiple area series for each argument.
