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。
