Percent Stacked Spline Area Chart

Percent Stacked Spline Area Chart consists of several spline area series stacked on top of one another. The minimum and maximum values on the Y-axis scale are 0 and 100% respectively.

The height of each series in Percent Stacked Spline Area Charts is proportional to its quantitative contribution to the total of all values in one category.

A Percent Stacked Spline Area Chart is an effective way to watch the variation of each of several variables side by side and their percentage ratio over time.

The general rule for this chart type is to use it for more than two series. However, the number of series should not be far larger to keep a Percent Stacked Spline Area Chart easy to read.
