• DateTimeContinuousAxis produces too many labels when zoom in to the max and then zoomed out with double clicking the slider

• Stroke property of LineSeries does not override palette color when set in style

• Light renderer sometimes leaves an empty pixel between two adjacent lines

• GetDataPointVisual method returns recycled containers.

• Doughnut slices don't explode on mouse click

• ScatterPoint visual elements are doubled when PointSize is changed

• Bar width is not recalculated on zoom with DateTimeContinuousAxis axis

• Annotations are positioned incorrectly when zooming on a DateTimeContinuousAxis

What's New

• Introduce Direct2D Rendering for ChartView

• Introduce light rendering for all series

• Introduce DefaultVisualStyleSelector

• Implement TickOrigin for LinearAxis

Q3 2012

• Added LineSeries.RenderMode property

  • SeriesRenderMode.Full (default) - the current rendering mechanism is used
    
  • SeriesRenderMode.Light - a new, faster rendering is used, which allows instant rendering of tens of thousands of points
    

• Added annotations support for RadCartesianChart and RadPolarChart

  • CartesianGridLineAnnotation – allows you to place custom gridline associated with a specific axis in RadCartesianChart
    
  • CartesianPlotBandAnnotation – allows you to place custom plot band (marked zone, stripe) associated with a specific axis in RadCartesianChart
    
  • CartesianCustomAnnotation – allows you to place custom content associated with specific horizontal and vertical axes in RadCartesianChart
    
  • PolarAxisGridLineAnnotation – allows you to place custom gridline associated with the polar axis in RadPolarChart
    
  • PolarAxisPlotBandAnnotation – allows you to place custom plot band (marked zone, stripe) associated with the polar axis in RadPolarChart
    
  • RadialAxisGridLineAnnotation – allows you to place custom gridline associated with the radial axis in RadPolarChart
    
  • RadialAxisPlotBandAnnotation – allows you to place custom plot band (marked zone, stripe) associated with the radial axis in RadPolarChart
    
  • PolarCustomAnnotation – allows you to place custom content in RadPolarChart.
    

• Added touch support

• Exposed public API for conversion from physical to data units for RadCartesianChart and RadPolarChart (i.e. point physically located at [x,y] coordinates in the drawing canvas, represents data value 400)

  • RadCartesianChart.ConvertPointToData(point)
    
  • RadCartesianChart.ConvertPointToData(point, horizontalAxis, verticalAxis)
    
  • RadPolarChart.ConvertPointToData(point)
    

• Added DoughnutSeries type

• Added RangeBarSeries type
