This series visualizes a set of rectangles (bars) representing each of the data points. The bars have numeric meaning in both directions - horizontal and vertical - and each bar is defined by horizontal and vertical start, and end values.

This series can be used to create histogram visualization. This can be done by using the properties of the data points or via the ChartHistogramSource.

Declaratively Defined Series

The following example shows how to define ScatterRangeBarSeries and populate its DataPoints collection.

Declaring a RangeBarSeries in XAML

<telerik:RadCartesianChart Palette="Fluent"> 
        <telerik:LinearAxis /> 
        <telerik:LinearAxis /> 
        <telerik:CartesianChartGrid MajorLinesVisibility="Y" /> 
            <telerik:ScatterRangeDataPoint HorizontalLow="10" HorizontalHigh="30" VerticalLow="0" VerticalHigh="5"/> 
            <telerik:ScatterRangeDataPoint HorizontalLow="30" HorizontalHigh="40" VerticalLow="0" VerticalHigh="6"/> 
            <telerik:ScatterRangeDataPoint HorizontalLow="40" HorizontalHigh="60" VerticalLow="0" VerticalHigh="5.5"/> 
            <telerik:ScatterRangeDataPoint HorizontalLow="60" HorizontalHigh="65" VerticalLow="0" VerticalHigh="6"/> 
            <telerik:ScatterRangeDataPoint HorizontalLow="65" HorizontalHigh="70" VerticalLow="0" VerticalHigh="7"/> 
            <telerik:ScatterRangeDataPoint HorizontalLow="70" HorizontalHigh="110" VerticalLow="0" VerticalHigh="6.5"/>

Data Binding

To bind the series to a collection of business objects, use its ItemsSource property. The series will create a new ScatterRangeDataPoint for each data item in the collection. To map the data item properties to the data point, use the HorizontalLowBinding, HorizontalHighBinding, VerticalLowBinding and VerticalHighBinding properties of the series.

Defining the data item model

public class ScatterBarInfo 
    public double HorizontalLow { get; set; } 
    public double HorizontalHigh { get; set; } 
    public double VerticalLow { get; set; } 
    public double VerticalHigh { get; set; } 
    public ScatterBarInfo(double horizontalLow, double horizontalHigh, double verticalLow, double verticalHigh) 
        this.HorizontalLow = horizontalLow; 
        this.HorizontalHigh = horizontalHigh; 
        this.VerticalLow = verticalLow; 
        this.VerticalHigh = verticalHigh; 

Populating with data

public MyUserControl()  
    var source = new ObservableCollection<ScatterBarInfo>(); 
    source.Add(new ScatterBarInfo(0, 4, 8, 10)); 
    source.Add(new ScatterBarInfo(6, 10, 1, 6)); 
    source.Add(new ScatterBarInfo(1, 1.5, 1, 6.5)); 
    source.Add(new ScatterBarInfo(3, 3.5, 4, 5)); 
    source.Add(new ScatterBarInfo(8, 11, 7, 11)); 
    this.scatterRangeBarSeries.ItemsSource = source;  

Specifying ScatterRangeBarSeries in XAML and setting its binding properties

<telerik:ScatterRangeBarSeries x:Name="scatterRangeBarSeries"  
               ItemsSource="{Binding}" /> 

See the Create Data-Bound Chart for more information on data binding in the RadChartView suite.

Palette Coloring

The chart provides a built-in palette support that allows you to automatically color each series or data points in a different color. То enable this, set the Palette property of the chart control. You can find more information about this feature in the Palettes section in the help documentation.

To change the palette mode of ScatterRangeBarSeries, set its PaletteMode property. The available options are Series and DataPoint (default value). This determines if each data point in the same series should use a different color from the palette, or the entire series (all data points) should have the same color.

Styling the Series

You can see how to style area series using different properties in the RangeBarSeries section of the Customizing CartesianChart Series help article.
