The role of Excel charts is to visualize and compare data. However, once the chart is created, it is a bit difficult to read precise data directly from it. In this case, you can add the data table to the chart. This article will introduce how to accomplish this task using Free Spire.XLS for Java.

Install the free API (2 Method)
1# Download the Free Spire.XLS for Java and unzip it, then add the Spire.Xls.jar file to your project as dependency.
2# Directly add the jar dependency to maven project by adding the following configurations to the pom.xml.

Sample Code

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);
    }
