本文演示如何用 DevExpress WPF控件的 DXCharts 创建2D点图。首先将 ChartControl.Diagram 属性部署到XYDiagram2D下，然后添加两个 PointSeries2D 对象到图像的 Diagram.Series集合。具体示例如下：

<Window x:Class="Point2DChart.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:dxc="http://schemas.devexpress.com/winfx/2008/xaml/charts" Title="Window1" Height="350" Width="620">
    <Grid>
        <dxc:ChartControl Name="chartControl1">
            <dxc:ChartControl.Diagram>
                <dxc:XYDiagram2D>
                    <dxc:XYDiagram2D.Series>
                        <dxc:PointSeries2D ColorEach="True" MarkerSize="20">
                            <dxc:PointSeries2D.Points>
                                <dxc:SeriesPoint Argument="A" Value="1" />
                                <dxc:SeriesPoint Argument="B" Value="3" />
                                <dxc:SeriesPoint Argument="C" Value="7" />
                                <dxc:SeriesPoint Argument="D" Value="4" />
                                <dxc:SeriesPoint Argument="E" Value="5" />
                                <dxc:SeriesPoint Argument="F" Value="3" />
                                <dxc:SeriesPoint Argument="G" Value="9" />
                                <dxc:SeriesPoint Argument="H" Value="11" />
                            </dxc:PointSeries2D.Points>
                            <!--region #PointOptions-->
                            <dxc:PointSeries2D.PointOptions>
                                <dxc:PointOptions PointView="ArgumentAndValues" />
                            </dxc:PointSeries2D.PointOptions>
                            <!--endregion #PointOptions-->
                            <!--region #MarkerModel-->
                            <dxc:PointSeries2D.MarkerModel>
                                <dxc:DollarMarker2DModel />

                            <dxc:PointSeries2D.Label>
                                <dxc:SeriesLabel ConnectorVisible="False" Indent="15" dxc:MarkerSeries2D.Angle="90" />
                            </dxc:PointSeries2D.Label>
