用于可视化图表数据的数据视图定义。
您可以为图表设置数据视图定义，以直观呈现从给定数据表派生的数据视图，而不是数据表本身。例如，如果图表的视图定义指明视图列为 [0, 3]，则在绘制图表时，系统只会考虑数据表格的第一列和第三列。如需查看有关如何定义和使用 Data 的示例，请参阅 Data。

This is achieved by specifying which columns to include in the view. For instance, defining view columns as `[0, 3]` would mean only the first and third columns of the data table are used for the chart. A DataViewDefinitionBuilder helps in creating and implementing such views.\n"]]
