Bar Series


RadCartesianChart visualizes each data point from the BarSeries as a rectangle. These rectangles (or bars) can be displayed either horizontally, or vertically, depending on whether the CategoricalAxis is the vertical axis or the horizontal. When the horizontal axis is categorical, the rectangles are displayed vertically. This means that they have equal width while their height represents the numerical value of each of the data points. On the other hand, when the vertical axis is categorical, the rectangles have equal height, while their width represents the value of the data point.

The BarSeries inherits from CategoricalSeries and requires one CategoricalAxis and one NumericalAxis.

Here is an example how to create RadCartesianChart with Bar Series:

First, create the needed business objects, for example:

public class CategoricalData
    public object Category { get; set; }

    public double Value { get; set; }

Then create a ViewModel:

public class CategoricalDataViewModel
    public ObservableCollection<CategoricalData> Data { get; set; }

    public CategoricalDataViewModel()
        this.Data = GetCategoricalData();

    private static ObservableCollection<CategoricalData> GetCategoricalData()
        var data = new ObservableCollection<CategoricalData>
            new CategoricalData { Category = "A", Value = 101 },
            new CategoricalData { Category = "B", Value = 45 },
            new CategoricalData { Category = "C", Value = 77 },
            new CategoricalData { Category = "D", Value = 15 },
            new CategoricalData { Category = "E", Value = 56 },
        return data;

Finally, use the following snippet to declare a RadCartesianChart with Bar Series in XAML:

        <local:CategoricalDataViewModel />
        <telerikChart:CategoricalAxis LabelFitMode="MultiLine" />
        <telerikChart:NumericalAxis LabelFitMode="MultiLine" />
        <telerikChart:BarSeries ValueBinding="Value"
                                ItemsSource="{Binding Data}" />

Here is how it looks:
