LineSeries

This series is visualized on the screen as a straight line connecting all data points.

Declaratively defined series

You can use the following definition to display a simple LineSeries

[XAML] Example 1: Declaring a LineSeries in XAML

<telerik:RadCartesianChart Palette="Windows8">
<telerik:RadCartesianChart.HorizontalAxis>
    <telerik:CategoricalAxis/>
</telerik:RadCartesianChart.HorizontalAxis>
<telerik:RadCartesianChart.VerticalAxis>
    <telerik:LinearAxis />
</telerik:RadCartesianChart.VerticalAxis>
<telerik:RadCartesianChart.Series>
    <telerik:LineSeries>
        <telerik:LineSeries.DataPoints>
            <telerik:CategoricalDataPoint Category="January" Value="2" />
            <telerik:CategoricalDataPoint Category="February" Value="5" />
            <telerik:CategoricalDataPoint Category="March" Value="3" />
            <telerik:CategoricalDataPoint Category="April" Value="10" />
            <telerik:CategoricalDataPoint Category="May" Value="9" />
            <telerik:CategoricalDataPoint Category="June" Value="7" />
            <telerik:CategoricalDataPoint Category="July" Value="1" />
        </telerik:LineSeries.DataPoints>
    </telerik:LineSeries>
</telerik:RadCartesianChart.Series>
</telerik:RadCartesianChart>

Properties

  • CategoryBinding: A property of type DataPointBinding that gets or sets the property path that determines the category value of the data point.
  • ValueBinding: A property of type DataPointBinding that gets or sets the property path that determines the value of the data point.
  • DashArray: A property of type DoubleCollection that gets or sets the dash pattern applied to the line series itself.
  • Stroke: A property of type Brush that gets or sets the stroke of the line series.
  • StrokeShapeStyle: A property of type Style that gets or sets the style of the stroke of the line series. The property accepts a style that targets an object of type Path.

Data Binding

You can use the ValueBinding and CategoryBinding properties of the LineSeries to bind the DataPoints’ properties to the properties from your view models.

[C#] Example 2: Defining the view model

public class PlotInfo
{
    public string Category { get; set; }
    public double Value { get; set; }
}

//.......
this.DataContext = new ObservableCollection<PlotInfo>
{
    new PlotInfo() { Category = "January", Value = 2},
    //....
};

[XAML] Example 3: Specify a LineSeries in XAML

<telerik:LineSeries ItemsSource="{Binding}" CategoryBinding="Category" ValueBinding="Value" />

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

Styling the Series

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

Additionally, you can use the Palette property of the chart to change the colors of the LineSeries on a global scale. You can find more information about this feature in the Palettes section in our help documentation.
