How to Create Pivot Chart from Pivot Table in Excel using Java?

A Pivot Chart is used to analyze data of a table with very little effort (and no formulas) and it gives you the big picture of your raw data. It allows you to analyze data using various types of graphs and layouts. It is considered to be the best chart during a business presentation that involves huge data. To add a pivot chart to an Excel worksheet, you need to use the WorksheetChartsCollection.add method. Before Creating Pivot Chart first needs to go through how to Create Pivot Table in excel using Java. Now let’s discuss steps to create a pivot chart in an Excel file in Java using Free Spire.XLS for Java API.

Step by Step Implementation

Step 1: Load the Excel file

Workbook workbook = new Workbook()
String workbookName = "Geeks_For_Geeks.xlsx";
workbook.loadFromFile(workbookName);

Step 2: Get the first worksheet

Worksheet sheet = workbook.getWorksheets().get(0);

Step 3: Get the first pivot table in the worksheet

IPivotTable pivotTable = sheet.getPivotTables().get(0);

Step 4: Add a clustered column chart based on the pivot table to the second worksheet

Chart chart = workbook.getWorksheets().get(1).getCharts().add(ExcelChartType.ColumnClustered, pivotTable);

 Step 5: Set chart position

chart.setTopRow(2);
chart.setBottomRow(15);

 Step 6: Set chart title

chart.setChartTitle("Total");

Step 7: Save the result file

workbook.saveToFile(workbookName, ExcelVersion.Version2013);

Let’s write Java Program to create a pivot chart from a pivot table in a spreadsheet.

Java

import com.spire.xls.*;
import com.spire.xls.core.IPivotTable;

class GFG {
    public static void main(String[] args)
    {
        // Load the Excel file
        Workbook workbook = new Workbook();
        String workbookName = "Geeks_For_Geeks.xlsx";
        workbook.loadFromFile(workbookName);

        // 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 to the second worksheet
        Chart chart
            = workbook.getWorksheets()
                  .get(1)
                  .getCharts()
                  .add(ExcelChartType.ColumnClustered,
                       pivotTable);

        // Set chart position
        chart.setTopRow(2);
        chart.setBottomRow(15);

        // Set chart title
        chart.setChartTitle("Total");

        // Save the result file
        workbook.saveToFile(workbookName,
                            ExcelVersion.Version2013);
        System.out.println(workbookName
                           + " is written successfully");
    }
}

Output: On the console window when the program is successfully executed.

GeeksForGeeks.xlsx is written successfully.

Output: On the Workbook(excel file)
