WPF界面开发工具DevExpress WPF使用教程：使用自动生成的序列创建3D图表（Part 3)

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。

本教程将指导您完成根据基础数据源自动创建3D系列所需的步骤。

• Step 1. 编写一个应用程序
• Step 2. 添加图表并将其绑定到数据
• Step 3. 自定义图表外观
• 结果

Step 3. 自定义图表外观

在此步骤中，您将学习如何配置外观图设置，为此请按照以下步骤操作。

• 要修改所有生成系列的外观，请使用此系列模板。要创建新模板，请在Properties窗口中找到Series3DDataSourceAdapter.SeriesTemplate 属性，然后单击New按钮。

• 然后，更改系列视图。 为此请找到Series3DBase.View属性，然后在下拉列表中选择Bubble3DSeriesView项目。

• 然后修改系列点表单，为此将Marker3DSeriesView.MarkerModel属性指定为Marker3DSpherePointModel对象。

• 将Bubble3DSeriesView.MaxSize属性定义为0.5，以设置最大气泡大小。 将Bubble3DSeriesView.MinSize属性定义为0.1，以设置最小气泡大小。

结果

完成上述所有步骤后，您的代码将显示如下。
