XYSeries.Data Property

Gets or sets the series data.

Namespace: DevExpress.Maui.Charts

Assembly: DevExpress.Maui.Charts.dll

NuGet Package: DevExpress.Maui.Charts

Declaration

public IXYSeriesData Data { get; set; }

Property Value

Type	Description
IXYSeriesData	An object that supplies data for the series.

Example

For example, to bind a spline series to data, set its Data property to a SeriesDataAdapter object. Use the adapter’s properties to specify the data source and its fields that contain arguments and values (this series type requires one argument and one value for a data point).

Xaml

<ContentPage.BindingContext>
    <local:MainViewModel/>
</ContentPage.BindingContext>
<dxc:ChartView>
    <dxc:ChartView.Series>
        <dxc:SplineSeries>
            <dxc:SplineSeries.Data>
                <dxc:SeriesDataAdapter DataSource="{Binding PowerConsumptionCenterBranch}"
                                       ArgumentDataMember="Time">
                    <dxc:ValueDataMember Type="Value" Member="Power"/>
                </dxc:SeriesDataAdapter>

Important

ChartView chooses the X-axis type depending on data in the first series. If you need to explicitly specify argument axis type for the chart or an individual series, use the ChartView.AxisX or Series.AxisX property. The assigned object should be compatible with the series data type. Otherwise, the chart does not display the series.

You can create a custom data adapter. This will help you support custom data supply scenarios. For example, you can generate series points dynamically without a data storage.
