SparkLineSeries
SparkLineSeries plot their CategoricalSparkDataPoint on Cartesian Area. The following example shows how you can create the line series.
Create SparkLineSeries
public void CreateLineSeries()
{
var lineSeries = new SparkLineSeries();
lineSeries.DataPoints.Add(new CategoricalSparkDataPoint(13));
lineSeries.DataPoints.Add(new CategoricalSparkDataPoint(20));
lineSeries.DataPoints.Add(new CategoricalSparkDataPoint(15));
lineSeries.DataPoints.Add(new CategoricalSparkDataPoint(5));
lineSeries.DataPoints.Add(new CategoricalSparkDataPoint(29));
lineSeries.DataPoints.Add(new CategoricalSparkDataPoint(8));
lineSeries.DataPoints.Add(new CategoricalSparkDataPoint(22));
lineSeries.ShowHighPointIndicator = true;
lineSeries.ShowLowPointIndicator = true;
lineSeries.HighPointShape = new StarShape(5, 3);
this.radSparkline1.Series = lineSeries;
}
Public Sub CreateLineSeries()
Dim lineSeries = New SparkLineSeries()
lineSeries.DataPoints.Add(New CategoricalSparkDataPoint(13))
lineSeries.DataPoints.Add(New CategoricalSparkDataPoint(20))
lineSeries.DataPoints.Add(New CategoricalSparkDataPoint(15))
lineSeries.DataPoints.Add(New CategoricalSparkDataPoint(5))
lineSeries.DataPoints.Add(New CategoricalSparkDataPoint(29))
lineSeries.DataPoints.Add(New CategoricalSparkDataPoint(8))
lineSeries.DataPoints.Add(New CategoricalSparkDataPoint(22))
lineSeries.ShowHighPointIndicator = True
lineSeries.ShowLowPointIndicator = True
lineSeries.HighPointShape = New StarShape(5, 3)
Me.radSparkline1.Series = lineSeries
End Sub
