DevExpress中定义的ChartControl很不错，很多项目直接使用这种控件。

本节讲述雷达图的样式设置

    <Grid>

        <Grid.Resources>

            <DataTemplate x:Key="LabelItemDataTemplate" DataType="dxc:SeriesLabelItem">

                <Border CornerRadius="8" Padding="8,1" Background="Transparent">

                    <!--<Border.Background>

                            <Binding Path="Color">

                            <Binding.Converter>

                            <dxc:BrushOverlayConverter/>

                            </Binding.Converter>

                            </Binding>

                        </Border.Background>-->

                    <TextBlock Text="{Binding Text}"/>

                </Border>

            </DataTemplate>

        </Grid.Resources>

                            <dxc:Range AutoSideMargins="False"></dxc:Range>

                        </dxc:RadarAxisY2D.WholeRange>

                    </dxc:RadarAxisY2D>

                </dxc:RadarDiagram2D.AxisY>

                <dxc:RadarDiagram2D.AxisX>

                    <dxc:RadarAxisX2D GridLinesBrush="#FF0885FF">

                        <dxc:RadarAxisX2D.Label>

                            <dxc:AxisLabel Foreground="White" Staggered="False">

                            </dxc:AxisLabel>

                    </dxc:RadarAxisX2D>

                </dxc:RadarDiagram2D.AxisX>

                <dxc:RadarDiagram2D.Series>

                    <dxc:RadarAreaSeries2D Transparency="0.7" Brush="GreenYellow">

                        <dxc:RadarAreaSeries2D.MarkerModel>

                            <dxc:CustomMarker2DModel>

                                <dxc:CustomMarker2DModel.PointTemplate>

                                    <ControlTemplate TargetType="dxc:CustomModelControl">

                                        <Ellipse Width="4" Height="4" Fill="GreenYellow"></Ellipse>

                                    </ControlTemplate>

                                </dxc:CustomMarker2DModel.PointTemplate>

                            </dxc:CustomMarker2DModel>

                        </dxc:RadarAreaSeries2D.MarkerModel>

                        <dxc:RadarAreaSeries2D.Label>

                            <dxc:SeriesLabel Visible="True" ConnectorVisible="False" ElementTemplate="{StaticResource LabelItemDataTemplate}"

                                    Indent="0" dxc:CircularSeries2D.Angle="0"></dxc:SeriesLabel>

                        </dxc:RadarAreaSeries2D.Label>

                        <dxc:SeriesPoint Argument="C#" Value="95" Tag="30"></dxc:SeriesPoint>

                        <dxc:SeriesPoint Argument="Java" Value="20" Tag="100" />

                        <dxc:SeriesPoint Argument="Python" Value="60" Tag="30" />

                        <dxc:SeriesPoint Argument="Ruby" Value="80" Tag="20"/>

                        <dxc:SeriesPoint Argument="VB.Net" Value="50" Tag="0"/>

                        <dxc:SeriesPoint Argument="VBA" Value="90" Tag="62" />

                    </dxc:RadarAreaSeries2D>

                </dxc:RadarDiagram2D.Series>

            </dxc:RadarDiagram2D>

        </dxc:ChartControl>

    </Grid>

1、先设置主体，首先背景设置成透明

ShapeStyle="Polygon"是设置雷达图的形状，Polygon指多边形，Circle就是圆圈了。

　  RotationDirection="Clockwise"，指是数据否顺时针显示

2、设置AxisY　　

    <dxc:RadarDiagram2D.AxisY>

        <dxc:RadarAxisY2D GridLinesBrush="#FF0885FF" GridLinesMinorVisible="False" Brush="Transparent">

            <dxc:RadarAxisY2D.NumericScaleOptions>

                <dxc:ContinuousNumericScaleOptions AutoGrid="False" GridSpacing="20" GridOffset="0" ></dxc:ContinuousNumericScaleOptions>

            </dxc:RadarAxisY2D.NumericScaleOptions>

            <dxc:RadarAxisY2D.Label>

                <dxc:AxisLabel Visible="False"></dxc:AxisLabel>

            </dxc:RadarAxisY2D.Label>

            <dxc:RadarAxisY2D.WholeRange>

                <dxc:Range MinValue="0" MaxValue="100" AutoSideMargins="False"></dxc:Range>

            </dxc:RadarAxisY2D.WholeRange>

        </dxc:RadarAxisY2D>

    </dxc:RadarDiagram2D.AxisY>
GridLinesMinorVisible设置是否补充线条,
AutoGrid="False" GridSpacing="20"设置刻度间隔
dxc:AxisLabel Visible="False"这个可以设置是否显示Y刻度
Range 当然就是范围了，默认不设置也没问题

3、设置AxisX
    <dxc:RadarDiagram2D.AxisX>

        <dxc:RadarAxisX2D GridLinesVisible="True" Interlaced="False" GridLinesMinorVisible="False" GridLinesBrush="#FF0885FF">

            <dxc:RadarAxisX2D.Label>

                <dxc:AxisLabel Foreground="White">

                </dxc:AxisLabel>

            </dxc:RadarAxisX2D.Label>

        </dxc:RadarAxisX2D>

    </dxc:RadarDiagram2D.AxisX>
GridLinesBrush设置中间交叉线的颜色。
dxc:AxisLabel设置数据标题的样式
4、数据
    <dxc:RadarDiagram2D.Series>

        <dxc:RadarAreaSeries2D Transparency="0.7" Brush="GreenYellow">

            <dxc:RadarAreaSeries2D.MarkerModel>

                <dxc:CustomMarker2DModel>

                    <dxc:CustomMarker2DModel.PointTemplate>

                        <ControlTemplate TargetType="dxc:CustomModelControl">

                            <Ellipse Width="4" Height="4" Fill="GreenYellow"></Ellipse>

                        </ControlTemplate>

                    </dxc:CustomMarker2DModel.PointTemplate>

                </dxc:CustomMarker2DModel>

            </dxc:RadarAreaSeries2D.MarkerModel>

            <dxc:RadarAreaSeries2D.Label>

                <dxc:SeriesLabel Visible="True" ConnectorVisible="False" ElementTemplate="{StaticResource LabelItemDataTemplate}"

                                    Indent="0" dxc:CircularSeries2D.Angle="0"></dxc:SeriesLabel>

            </dxc:RadarAreaSeries2D.Label>

            <dxc:SeriesPoint Argument="C#" Value="95" Tag="30"></dxc:SeriesPoint>

            <dxc:SeriesPoint Argument="Java" Value="20" Tag="100" />

            <dxc:SeriesPoint Argument="Python" Value="60" Tag="30" />

            <dxc:SeriesPoint Argument="Ruby" Value="80" Tag="20"/>

            <dxc:SeriesPoint Argument="VB.Net" Value="50" Tag="0"/>

            <dxc:SeriesPoint Argument="VBA" Value="90" Tag="62" />

        </dxc:RadarAreaSeries2D>

    </dxc:RadarDiagram2D.Series>
CustomMarker2DModel.PointTemplate可以重写数据点的模板
dxc:SeriesLabel Visible="True" ConnectorVisible="False" ElementTemplate="{StaticResource LabelItemDataTemplate}"  这个设置数据值的显示样式
值得一提的是，雷达图中数据值默认显示的是Value，那如果需要的话，是否可以设置为其它值呢？答案是可以的，通过用Tag存储数据或者直接用数据绑定，然后在dxc:RadarAreaSeries2D.Label的模板中绑定父属性Tag或者绑定数据就行了。
