Stacked Spline Area 100% Charts
RadChart has been replaced by RadHtmlChart, Telerik's client-side charting component. If you are considering RadChart for new development, examine the RadHtmlChart documentation and online demos first to see if it will fit your development needs. If you are already using RadChart in your projects, you can migrate to RadHtmlChart by following these articles: Migrating Series, Migrating Axes, Migrating Date Axes, Migrating Databinding, Features parity. Support for RadChart is discontinued as of Q3 2014, but the control will remain in the assembly so it can still be used. We encourage you to use RadHtmlChart for new development.
The Stacked Spline Area 100% chart is a variation of the Spline Area chart. The areas are stacked so that each series adjoins but does not overlap the preceding series. This chart displays contributions for each data point to the category as a percentage.
To create a vertical Stacked Spline Area Chart 100% chart, set the SeriesOrientation property to Vertical. Set the RadChart DefaultType property or ChartSeries.Type to StackedSplineArea100.
To create a horizontal Stacked Spline Area Chart 100% chart, set the SeriesOrientation property to Horizontal. Set the RadChart DefaultType property or ChartSeries.Type to StackedSplineArea100.
To display the label values as percentages, change the DefaultLabelValue for each chart series from "#Y" (the numeric value for each data point) to "#%" (the percentage of each data point to the category).
