Stacked Spline Area Chart

Stacked Spline Area Chart is built of several Spline Area Chart series placed on top of one another, i.e. stacked vertically. The height of each series is ruled by the corresponding value in each data point.

Stacked Spline Area Charts allow the viewer to follow the fluctuations of all variables one by one at the same time, in addition to watching the change of the total value.

A Stacked Spline Area Chart should not be used for less than three series. Meanwhile, such a type of graph might lose clarity if too many stacked series are present. A Stacked Spline Area Chart with only one series is intrinsically a regular Spline Area Chart.
