  • New Features
    • Added two new 2D chart types: StackedLine and StackedSpline
    • Added AxisY.ExtendDirection property. This property will define if and in which direction AxisY will automatically add an additional step in order to ensure there is always a gap between the graph and the chart area top/bottom end. It is respected only when AutoRange property is set to true and IsZeroBasedProperty is treated with higher priority. The possible values are:
      • AxisExtendDirection.None - the Y axis will not be extended 
      • AxisExtendDirection.Down - the Y axis will have an additional item at the bottom 
      • AxisExtendDirection.Up - the Y axis will have an additional item at the top 
      • AxisExtendDirection.Both - the Y axis will have an additional item at both - top and bottom 
      • AxisExtendDirection.Smart - acts like AxisExtendDirection.Both with a single difference: the axis will never be extended outside the 0 value
    • New series types - StackedLine and StackedSpline
    • Exposed Style properties for customization of the visual elements of RadChart: 
      • RadChart.TitleStyle - gets or sets the title style

      • SeriesDefinition.PointMarkItemStyle - gets or sets the Style associated with each point mark (where applicable)
      • SeriesDefinition.SeriesItemLabelStyle - gets or sets the series item label style
      • ChartArea.AxisXStyle - gets or sets the axis X style
      • ChartArea.AxisYStyle - gets or sets the axis Y style

  • New Features
    • Semi-circle styles for radial gauges
    • Quadrant-like styles for radial gauges  


  • New Features
    • Save/Load Layout mechanism - When building complex layouts with Telerik Docking the users will often expect to persist the layout from one session to another. This can be easily achieved with the advanced Save/Load Layout mechansim of the Telerik Docking control. RadDocking provides a method that stores the entire layout in a stream containing XML. Then, you can simply restore the layout from its previous state. In addition, you can choose to save the stream elsewhere, in a textbox or directly in the isolated storage.
