Create Pivot Chart in Excel using Java

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.

<repositories>
        <repository>
            <id>com.e-iceblue</id>
            <name>e-iceblue</name>

        </repository>

<dependencies>
    <dependency>
        <groupId>e-iceblue</groupId>
        <artifactId>spire.xls.free</artifactId>
        <version>3.9.1</version>
    </dependency>
</dependencies>

Java Code:

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);
    }
}
