.NET MAUI Cartesian Chart Line Series

Updated on Aug 12, 2026

The LineSeries connects the data points with straight line segments.

Data Binding

The LineSeries binds to data through the following properties:

• ItemsSource (IEnumerable)—Defines the collection of data items that the series plots.
• HorizontalBinding (string)—Defines the name of the data-item member that provides the value of each data point and this value is plotted along the horizontal axis.
• VerticalBinding (string)—Defines the name of the data-item member that provides the value of each data point and this value is plotted along the vertical axis.
• VerticalAxis (Telerik.Maui.Controls.Charts.ChartAxis)—Defines the vertical axis for the series which values resolved from the VerticalBinding property are plotted against.
• HorizontalAxis (Telerik.Maui.Controls.Charts.ChartAxis)—Defines the horizontal axis for the series which values resolved from the HorizontalBinding property are plotted against.

Line Customization

Use the following properties to customize the appearance of the line:

• Stroke (Brush)—Defines the brush to paint the stroke of the line.
• StrokeThickness (double)—Defines the thickness of the line stroke.

Labels Customization

Use the following properties to configure the labels visualized for each data point:

• ShowLabels (bool)—Defines whether the axis labels will be displayed.
• LabelOffset (Size)—Defines the offset of the labels from the line.
• LabelStyle (Style with target type ChartLabelAppearance)—Defines the style of the axis labels.

Example

The following example shows how to define a LineSeries.

1. Define the LineSeries and the chart definition in XAML:

XAML

<charts:RadCartesianChart>
    <charts:RadCartesianChart.BindingContext>
        <models:CategoricalViewModel />
    </charts:RadCartesianChart.BindingContext>
    <charts:RadCartesianChart.Axes>
        <charts:CategoricalAxis />
        <charts:NumericalAxis />
    </charts:RadCartesianChart.Axes>
    <charts:RadCartesianChart.Series>
        <charts:LineSeries HorizontalBinding="Category"
                           VerticalBinding="Value"
                           ItemsSource="{Binding Data}" />
    </charts:RadCartesianChart.Series>
</charts:RadCartesianChart>

2. Add the charts namespace:

XAML

xmlns:charts="clr-namespace:Telerik.Maui.Controls.Charts;assembly=Telerik.Maui.Controls"

3. Add the data model:

C#

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

    public double Value { get; set; }
}

4. Add the ViewModel:

C#

public class CategoricalViewModel
{
    public ObservableCollection<CategoricalData> Data { get; } = new ObservableCollection<CategoricalData>
    {
        new CategoricalData { Category = "Jan", Value = 42 },
        new CategoricalData { Category = "Feb", Value = 58 },
        new CategoricalData { Category = "Mar", Value = 37 },
        new CategoricalData { Category = "Apr", Value = 71 },
        new CategoricalData { Category = "May", Value = 64 },
        new CategoricalData { Category = "Jun", Value = 88 },
    };
}

This is the result:

For a runnable example with the Cartesian Chart line series, go to the SDKBrowser Demo Application and navigate to the Charts > Series category.
