In Excel, we could use charts to visualize and compare data. However, once the charts are created, it becomes much difficult for us to read the data precisely from charts, adding a data table below the chart is a good solution. This article is going to introduce how to add a data table to an Excel chart in Java using Spire.XLS for Java.

import com.spire.xls.*;
import com.spire.xls.charts.ChartSerie;

public class AddDataTableToChart {
    public static void main(String[] args){
        //Create a new workbook
        Workbook workbook = new Workbook();
        //Get the first worksheet
        Worksheet sheet = workbook.getWorksheets().get(0);
        //Set sheet name
        sheet.setName("Demo");

        //Add Data to the sheet
        sheet.getRange().get("A1").setValue("Month");
        sheet.getRange().get("A2").setValue("Jan.");
        sheet.getRange().get("A3").setValue("Feb.");
        sheet.getRange().get("A4").setValue("Mar.");
        sheet.getRange().get("A5").setValue("Apr.");
        sheet.getRange().get("A6").setValue("May.");
        sheet.getRange().get("A7").setValue("Jun.");
        sheet.getRange().get("B1").setValue("Peter");
        sheet.getRange().get("B2").setNumberValue(3.3);
        sheet.getRange().get("B3").setNumberValue(2.5);
        sheet.getRange().get("B4").setNumberValue(2.0);
        sheet.getRange().get("B5").setNumberValue(3.7);
        sheet.getRange().get("B6").setNumberValue(4.5);
        sheet.getRange().get("B7").setNumberValue(4.0);
        sheet.getRange().get("C1").setValue("George");
        sheet.getRange().get("C2").setNumberValue(3.8);
        sheet.getRange().get("C3").setNumberValue(3.2);
        sheet.getRange().get("C4").setNumberValue(1.7);
        sheet.getRange().get("C5").setNumberValue(3.5);
        sheet.getRange().get("C6").setNumberValue(4.5);
        sheet.getRange().get("C7").setNumberValue(4.3);
        sheet.getRange().get("D1").setValue("Macbeth");
        sheet.getRange().get("D2").setNumberValue(3.0);
        sheet.getRange().get("D3").setNumberValue(2.8);
        sheet.getRange().get("D4").setNumberValue(3.5);
        sheet.getRange().get("D5").setNumberValue(2.3);
        sheet.getRange().get("D6").setNumberValue(3.3);
        sheet.getRange().get("D7").setNumberValue(3.8);

        //Add a chart to the sheet
        Chart chart = sheet.getCharts().add(ExcelChartType.ColumnClustered);
        //Set chart data
        chart.setDataRange(sheet.getRange().get("B1:D7"));
        chart.setSeriesDataFromRange(false);
        //Set chart position
        chart.setTopRow(8);
        chart.setBottomRow(28);
        chart.setLeftColumn(3);
        chart.setRightColumn(11);
        //Set chart title
        chart.setChartTitle("Chart with Data Table");
        chart.getChartTitleArea().isBold(true);
        chart.getChartTitleArea().setSize(12);
        //Set category labels for the first series of the chart
        ChartSerie cs1 = chart.getSeries().get(0);
        cs1.setCategoryLabels(sheet.getRange().get("A2:A7"));

        //Add data table to the chart
        chart.hasDataTable(true);

        //Save the result file
        workbook.saveToFile("AddDataTable.xlsx", ExcelVersion.Version2010);
    }
}

Output:
