SparkScatterSeries

Updated over 6 months ago

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

C#

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;
}

VB.NET

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

The essential properties of SparkScatterSeries are:

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