In my previous posts, I've introduced how to create an Excel pivot table with the 3rd party library--Free Spire.XLS for Java. This article will demonstrates how to create a pivot chart based on the data in pivot table.
Installation
Method 1: Download the Free Spire.XLS for Java and unzip it, then add the Spire.Xls.jar file to your project as dependency.
Method 2: Directly add the jar dependency to maven project by adding the following configurations to the pom.xml.

import com.spire.xls.*; import com.spire.xls.core.IPivotTable; public class CreatePivotChart { public static void main(String[] args) { //Load the Excel file Workbook workbook = new Workbook(); workbook.loadFromFile("data.xlsx"); //Get the first worksheet Worksheet sheet = workbook.getWorksheets().get(0); //get the first pivot table in the worksheet IPivotTable pivotTable = sheet.getPivotTables().get(0); //Add a clustered column chart based on the pivot table data Chart chart = sheet.getCharts().add(ExcelChartType.ColumnClustered, pivotTable); //Set chart position chart.setTopRow(14); chart.setBottomRow(25); //Set chart title chart.setChartTitle("Total"); //Save the result file workbook.saveToFile("CreatPivotChart.xlsx", ExcelVersion.Version2013); } }
