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. Also, converts Excel documents to PDF files.

This library also supports creating PivotTables and PivotCharts. PivotCharts are created by IChart interface by setting its pivot source as 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");
}
