Stacked Groups

  • Demo Configurator

Stack Type

Stacked Column, Bar and Radar-Column series in RadHtmlChart can be clustered in groups since the Q3 2013 release.

Series that will be stacked in a separate group must have the same group name set in their GroupName property. If the property is left blank, all series will be placed in one default stack. Setting the GroupName property of any series automatically sets the Stacked property of the first series to true, so it is not required to be explicitly set.

< telerik:RadHtmlChart runat = "server" ID = "RadBarChart" Width = "300px" Height = "250px" >
     < PlotArea >
          < Series >
               < telerik:BarSeries DataFieldY = "Value1" GroupName = "Group1" >
               </ telerik:BarSeries >
               < telerik:BarSeries DataFieldY = "Value2" GroupName = "Group1" >
               </ telerik:BarSeries >
          </ Series >
     </ PlotArea >
</ telerik:RadHtmlChart >

You can further examine the stacking of Series in the Stacked Series example.

Optionally, you can also use the StackType property to change the stack type from the default (Normal) type to Stack100, which will lead you to a 100% stacked chart. More about the Stack100 type is explained in the Stacked 100% Series demo.
