如何使用 C++ 管理带有 PivotOptions 的 PivotGraph（数据透视图）

什么是数据透视图

Excel中的数据透视图是从数据透视表中创建的数据的图形表示。它允许用户通过以图表形式汇总和显示信息来动态可视化和分析数据。数据透视图是交互式的，可以轻松修改以显示数据的不同视角，因此是Excel中数据分析和演示的强大工具。

如何使用数据透视表选项管理数据透视图

通过使用 C++ 结合 Aspose.Cells for JavaScript，您可以使用 PivotOptions 来管理数据透视图。

            // Instantiating a Workbook object from the uploaded file

            // Hide ZoneFilter in PivotChart
            opt.dropZoneFilter = false; // HideZoneFilter

            // Save the file and provide download link
