How to refresh an Excel pivot chart in C#, VB.NET

Syncfusion® Excel (XlsIO) library is a .NET Excel library used to create, read, and edit Excel documents. It also converts Excel documents to PDF files.

This library supports creating PivotTables and PivotCharts. PivotCharts are created using the IChart interface by setting their pivot source as a PivotTable.

Refreshing a PivotChart can be achieved by changing the pivot chart’s pivot table’s cache data source. The following complete code snippet explains this.

C#

using (ExcelEngine excelEngine = new ExcelEngine())
{
    IApplication application = excelEngine.Excel;
    application.DefaultVersion = ExcelVersion.Xlsx;
 
    IWorkbook workbook = application.Workbooks.Open("../../Data/PivotChart.xlsx");
    IWorksheet worksheet = workbook.Worksheets[0];
    IWorksheet pivotsheet = workbook.Worksheets[1];
    IPivotTable pivotTable = pivotsheet.PivotTables[0];
 
    (pivotTable as PivotTableImpl).Cache.SourceRange = worksheet["A1:H40"];
 
    workbook.SaveAs("Output.xlsx");
    System.Diagnostics.Process.Start("Output.xlsx");
}

A complete working sample can be downloaded from RefreshPivotChart.zip.
