Unbound Mode

When using the unbound mode you need to create the series and manually add data points. Then you need to set the Series property of the RadSparkline. This is demonstrated in the following example.

Create Series Manually

var barSeries = new SparkBarSeries();
barSeries.DataPoints.Add(new CategoricalSparkDataPoint(13));
barSeries.DataPoints.Add(new CategoricalSparkDataPoint(20));
barSeries.DataPoints.Add(new CategoricalSparkDataPoint(15));
barSeries.DataPoints.Add(new CategoricalSparkDataPoint(-5));
barSeries.DataPoints.Add(new CategoricalSparkDataPoint(29));
barSeries.DataPoints.Add(new CategoricalSparkDataPoint(8));
barSeries.DataPoints.Add(new CategoricalSparkDataPoint(-22));
barSeries.DataPoints.Add(new CategoricalSparkDataPoint(22));
barSeries.DataPoints.Add(new CategoricalSparkDataPoint(12));
barSeries.ShowHighPointIndicator = true;
barSeries.ShowLowPointIndicator = true;
barSeries.ShowFirstPointIndicator = true;
barSeries.ShowLastPointIndicator = true;
barSeries.ShowNegativePointIndicators = true;

this.radSparkline1.ShowAxis = true;
this.radSparkline1.AxisDrawMode = AxisDrawMode.AboveSeries;
this.radSparkline1.Series = barSeries;

Dim barSeries = New SparkBarSeries()
barSeries.DataPoints.Add(New CategoricalSparkDataPoint(13))
barSeries.DataPoints.Add(New CategoricalSparkDataPoint(20))
barSeries.DataPoints.Add(New CategoricalSparkDataPoint(15))
barSeries.DataPoints.Add(New CategoricalSparkDataPoint(-5))
barSeries.DataPoints.Add(New CategoricalSparkDataPoint(29))
barSeries.DataPoints.Add(New CategoricalSparkDataPoint(8))
barSeries.DataPoints.Add(New CategoricalSparkDataPoint(-22))
barSeries.DataPoints.Add(New CategoricalSparkDataPoint(22))
barSeries.DataPoints.Add(New CategoricalSparkDataPoint(12))
barSeries.ShowHighPointIndicator = True
barSeries.ShowLowPointIndicator = True
barSeries.ShowFirstPointIndicator = True
barSeries.ShowLastPointIndicator = True
barSeries.ShowNegativePointIndicators = True
Me.radSparkline1.ShowAxis = True
Me.radSparkline1.AxisDrawMode = AxisDrawMode.AboveSeries
Me.radSparkline1.Series = barSeries

You can see the result in the following image.
