用於呈現圖表資料的資料檢視定義。
您可以為圖表設定資料檢視定義，以便將從指定資料表衍生的檢視畫面視覺化，而非資料表本身。舉例來說，如果圖表的檢視定義指出檢視欄為 [0, 3]，則繪製圖表時，系統只會考量資料表的第一和第三欄。請參閱 Data，瞭解如何定義及使用 Data 的範例。

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"]]
