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)
