# SparkBarSeries

**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
```

| **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.                                                       |
