Percent Stacked Spline Area Chart

The Percent Stacked SplineArea Chart is represented by SplineArea series that are stacked one on another. The minimum and maximum scale values of the Y-axis are 0% and 100% respectively.The height of each series is proportional to its quantitative contribution to the total of all values across one category (on the X-axis).

Percent Stacked SplineArea Charts are 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 type of graph is to use it for more than two series.However, the number of series should not be far larger to keep the chart easy to read.
