SparkScatterSeries

Unlike Categorical series, ScatterSeries plots its data upon two numerical axes. Scatter series identify the position of each ScatterDataPoint using two numerical values - XValue and YValue for the horizontal and vertical axes respectively, just like in the typical Cartesian coordinate system. Here is how to create two SparkScatterSeries and populate them manually:

Create SparkScatterSeries

public void CreateScatterSeries()
{
    var scatterSeries = new SparkScatterSeries();
    scatterSeries.DataPoints.Add(new ScatterSparkDataPoint(13, 1));
    scatterSeries.DataPoints.Add(new ScatterSparkDataPoint(20, 2));
    scatterSeries.DataPoints.Add(new ScatterSparkDataPoint(15, 3));
    scatterSeries.DataPoints.Add(new ScatterSparkDataPoint(5, 4));
    scatterSeries.DataPoints.Add(new ScatterSparkDataPoint(29, 5));
    scatterSeries.DataPoints.Add(new ScatterSparkDataPoint(8, 6));
    scatterSeries.DataPoints.Add(new ScatterSparkDataPoint(22, 71));
    scatterSeries.ShowHighPointIndicator = true;
    scatterSeries.ShowLowPointIndicator = true;
    this.radSparkline1.Series = scatterSeries;
}

Public Sub CreateScatterSeries()
    Dim scatterSeries = New SparkScatterSeries()
    scatterSeries.DataPoints.Add(New ScatterSparkDataPoint(13, 1))
    scatterSeries.DataPoints.Add(New ScatterSparkDataPoint(20, 2))
    scatterSeries.DataPoints.Add(New ScatterSparkDataPoint(15, 3))
    scatterSeries.DataPoints.Add(New ScatterSparkDataPoint(5, 4))
    scatterSeries.DataPoints.Add(New ScatterSparkDataPoint(29, 5))
    scatterSeries.DataPoints.Add(New ScatterSparkDataPoint(8, 6))
    scatterSeries.DataPoints.Add(New ScatterSparkDataPoint(22, 71))
    scatterSeries.ShowHighPointIndicator = True
    scatterSeries.ShowLowPointIndicator = True
    Me.radSparkline1.Series = scatterSeries
End Sub

Property	Description
HighValue	Gets the high value data point.
LowValue	Gets the low value data point.
