Text box allows people to enter text in it and move it arbitrarily. When dealing with the chart in Excel document, if the text description of the original chart is not specific enough, you can add additional information to the chart by adding text boxes to it. This article will introduce how to add a text box to a chart programmatically using Spire.XLS for Java.

Add a Text Box to a Chart

The detailed steps are listed as below.

• Create a Workbook instance and load a sample Excel document using Workbook.loadFromFile() method.
• Get a specified worksheet using Workbook.getWorksheets().get() method.
• Get a specific chart using Worksheet.getCharts().get() method.
• Add a text box to the chart using Chart.getShapes().addTextBox() method, and then add text content in the text box using ITextBoxLinkShape.setText() method.
• Set the size and position of the added text box using the method offered by ITextBoxLinkShape interface.
• Save the document to file using Workbook.saveToFile() method.

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

public class addTextBoxToChart {
    public static void main(String[] args)throws Exception {
        //Create a Workbook instance
        Workbook workbook = new Workbook();

        //Load an Excel document
        workbook.loadFromFile("DoughnutChart.xlsx");

        //Get the first worksheet
        Worksheet sheet = workbook.getWorksheets().get(0);

        //Get the first chart
        Chart chart = sheet.getCharts().get(0);

        //Add a text box to the chart
        ITextBoxLinkShape textbox = chart.getShapes().addTextBox();
        textbox.setText("Modified by Louis on September 06, 2021");

        //Set the size and position of the text box
        textbox.setWidth(1100);
        textbox.setHeight(480);
        textbox.setLeft(2800);
        textbox.setTop(480);

        //Save the result file
        workbook.saveToFile("addTextBoxToChart.xlsx", ExcelVersion.Version2013);
    }
}
