DxPolarChartLineSeries<T, TArgument, TValue> Class

Defines a line series.

Assembly : DevExpress.Blazor.v25.2.dll

Declaration

csharp

public class DxPolarChartLineSeries<T, TArgument, TValue> :
    DxPolarChartBaseSeries<T, TArgument, TValue>

Type Parameters

Name	Description
T

The data type.

| | TArgument |

The series argument type.

| | TValue |

The series value type.

Remarks

The line series displays data as points joined by line segments.

Run Demo: Polar and Radar - Discrete Data

Declare a Line Series

Use the Polar Chart’s Data property to specify a data source.
Add a <DxPolarChartLineSeries> tag to the component’s markup.
Assign data source fields that contain arguments and values for data points to ArgumentField and ValueField properties.
Optional. Configure the series: customize appearance, add labels, choose selection and hover modes, etc.

Nested Component Structure

You can add the following child components to a line series:

DxChartSeriesLabelDefines a series label.DxChartSeriesLegendItemDefines an item that indicates a series in the legend.DxChartSeriesPointContains settings for points of the chart’s line- and area-based series.

The following code snippet declares these objects in the markup:

razor

@using System.Drawing

<DxPolarChart Data=@DataSource>
    <DxPolarChartLineSeries ArgumentField="@((DiscretePoint i) => i.Arg)"
                            ValueField="@((DiscretePoint i) => i.Day)">
        <DxChartSeriesLabel Visible="true" FormatPattern="{value:##.#}" />
        <DxChartSeriesPoint Color="Color.SlateBlue" />
        <DxChartSeriesLegendItem Text="Daily Temperature" />
    </DxPolarChartLineSeries>
</DxPolarChart>

Customize Appearance

The Polar Chart allows you to use the following options to customize a line series:

BreakOnEmptyPointsSpecifies whether the series should break on points with null values.ClosedSpecifies whether to connect first and last series points.ColorSpecifies the color of the series.DashStyleSpecifies the line style.WidthSpecifies the width of the line series.

razor

@using System.Drawing

<DxPolarChart Data=@DataSource>
    <DxPolarChartLineSeries ArgumentField="@((DiscretePoint i) => i.Arg)"
                            ValueField="@((DiscretePoint i) => i.Day)"
                            Width="1"
                            Color="Color.DarkSalmon"
                            DashStyle="ChartDashStyle.DashDotDot">
    </DxPolarChartLineSeries>
</DxPolarChart>
