SparkBarSeries

Updated over 6 months ago

SparkBarSeries are used to visualize data points as bar blocks where the height of each bar denotes the magnitude of its value. The following snippet demonstrates how to manually add SparkBarSeries.

Create SparkBarSeries

C#

public void CreateBarSeries()
{
    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.ShowHighPointIndicator = true;
    barSeries.ShowLowPointIndicator = true;
    this.radSparkline1.Series = barSeries;
}

VB.NET

Public Sub CreateBarSeries()
    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.ShowHighPointIndicator = True
    barSeries.ShowLowPointIndicator = True
    Me.radSparkline1.Series = barSeries
End Sub

The essential properties of SparkBarSeries are:

Property	Description
BaselineValue	Gets or sets the value of the base line splitting the area into Win and Loss halves.
HighValue	Gets the high value data point.
LowValue	Gets the low value data point.
