下载DevExpress v20.1完整版    DevExpress v20.1汉化资源获取

通过DevExpress WPF Controls,您能创建有着强大互动功能的XAML基础应用程序,这些应用程序专注于当代客户的需求和构建未来新一代支持触摸的解决方案。

在本教程中,您将完成可视化数据源所需的步骤。

应该执行以下步骤,本文我们将为大家介绍3个步骤及最后结果,更多完整内容欢迎持续关注!

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

本节中系列的外观将被配置,将分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颜色。

然后,展开model属性,并将其 Marker3DSpherePointModel.SphereDetalizationLevel 属性设置为Low,这将提高应用程序性能。

当前,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>

结果

下图演示了已启动的应用程序。
