Hi Wang,

Thank you for using our RadControls for Windows 8!

At this point RadLegendControl generates LegendItems per Series basis - only for PieChart it is per DataPoint basis. This is already logged as a feature request and it will be implemented in one of our next releases. Additionally I can suggest you as a workaround to add LegendItems manually for each Bar DataPoint. Here's an example:

<telerikPrimitives:RadLegendControl x:Name="LegendControl"/>

this.LegendControl.LegendItems.Add(new LegendItem() { Title = "point1", Fill = this.chart.Palette.GetBrush(0,PaletteVisualPart.Fill), Stroke = this.chart.Palette.GetBrush(0,PaletteVisualPart.Stroke) });
this.LegendControl.LegendItems.Add(new LegendItem() { Title = "point2", Fill = this.chart.Palette.GetBrush(1, PaletteVisualPart.Fill), Stroke = this.chart.Palette.GetBrush(1, PaletteVisualPart.Stroke) });
this.LegendControl.LegendItems.Add(new LegendItem() { Title = "point3", Fill = this.chart.Palette.GetBrush(2, PaletteVisualPart.Fill), Stroke = this.chart.Palette.GetBrush(2, PaletteVisualPart.Stroke) });

I hope this helps. Let me know if I can assist you any further.
