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，为此请依照以下步骤操作。

  • 要批改所有生成系列的外观，请应用此系列模板。要创立新模板，请在 Properties 窗口中找到 Series3DDataSourceAdapter.SeriesTemplate 属性，而后单击 New 按钮。

  • 而后，更改系列视图。为此请找到 Series3DBase.View 属性，而后在下拉列表中抉择 Bubble3DSeriesView 我的项目。

  • 而后批改系列点表单，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。

后果

实现上述所有步骤后，您的代码将显示如下。
