在本教程中，您将实现可视化数据源所需的步骤。

应该执行以下步骤，本文咱们将为大家介绍 3 个步骤及最初后果，更多残缺内容欢送继续关注！

  • Step 1. 编写一个应用程序
  • Step 2. 为图表和系列绑定增加数据
  • Step 3. 配置系列视图
  • 后果
Step 3. 配置系列视图

本节中系列的外观将被配置，将调配一个不同的系列视图。此外，通过点的 ColorIndex 值对点进行着色的着色器将用于提供色彩。

  • 关上 Series Collection Editor 而后抉择 Series3D，找到 Series3DBase.View 属性并将其设置为 Point3DSeriesView.。

开展视图属性，找到 Marker3DSeriesView.MarkerModel 属性并将其调配给 SphereMarker3DModel 对象。

而后，开展 model 属性，并将其 Marker3DSpherePointModel.SphereDetalizationLevel 属性设置为 Low，这将进步应用程序性能。

  • 找到 Series3DViewBase.Colorizer 属性并将其设置为 RangeColorizer3D。

扩大着色器的属性并将其 RangeColorizer3D.RangeStops 设置为 -0.4 0.4 1.8 2。

将 YellowPalette 对象指定为 PaletteColorizer3DBase.Palette 属性值。

将 RangeColorizer3D.ApproximateColors 设置为 true。

最初，将 RangeColorizer3D.ValueProvider 设置为新的 ColorObjectValueProvider3D 对象，而后单击 OK 敞开编辑器并保留更改。

以后，该系列的 XAML 标记应如下所示。
`<dxc:Series3D DisplayName=”Series 1″>
<dxc:Series3D.View>
<dxc:Point3DSeriesView>
<dxc:Point3DSeriesView.MarkerModel>
<dxc:Marker3DSpherePointModel SphereDetalizationLevel=”Low”/>
</dxc:Point3DSeriesView.MarkerModel>
<dxc:Point3DSeriesView.Colorizer>
<dxc:RangeColorizer3D RangeStops=”-0.4 0.4 1.8 2″
ApproximateColors=”True”>
<dxc:RangeColorizer3D.ValueProvider>
<dxc:ColorObjectValueProvider3D/>
</dxc:RangeColorizer3D.ValueProvider>
<dxc:RangeColorizer3D.Palette>
<dxc:YellowPalette/>
</dxc:RangeColorizer3D.Palette>
</dxc:RangeColorizer3D>
</dxc:Point3DSeriesView.Colorizer>
</dxc:Point3DSeriesView>
</dxc:Series3D.View>
<!–Point Source Configuration –>
</dxc:Series3D>`

后果

下图演示了已启动的应用程序。

以下代码是本入门课程的后果。
