How to Create Excel Pie Chart in Java

A pie chart, also known as a circle chart, which allow you to directly graph the overall proportions of each component. Pie chart helps you to analyze the abstract data more quickly and intuitively. This article will demonstrate how to create a pie chart in Excel in Java applications with the help of Spire.XLS for Java.

Install Spire.XLS for Java

First, you're required to add the Spire.Xls.jar file as a dependency in your Java program. The JAR file can be downloaded from this link. If you use Maven, you can easily import the JAR file in your application by adding the following code to your project's pom.xml file.

Create a circle chart

Circle chart is a regular pie chart, which is used to display a single data series in a circle-type structure, with each sector representing a different category. Spire.XLS for Java offers the Worksheet.getCharts().add(ExcelChartType.Pie) method to add a pie chart to Excel worksheet.

  • Create a Workbook instance.
  • Get a specified worksheet using Workbook.getWorksheets().get(sheetIndex) method.
  • Add some data to the worksheet and set values, styles and number format of the Excel cells.
  • Add a pie chart to the worksheet using Worksheet.getCharts().add(ExcelChartType.Pie) method.
  • Set data range for the chart through Chart.setDataRange() method.
  • Set position, title for the chart.
  • Save the document to file using Workbook.saveToFile() method. 
import com.spire.xls.*;
import com.spire.xls.charts.ChartSerie;
import java.awt.*;

public class pieChart {

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

        //get the first sheet and set its name
        Worksheet sheet = workbook.getWorksheets().get(0);
        sheet.setName("Pie Chart");

        //set value of specified cell
        sheet.getCellRange("A1").setValue("System");
        sheet.getCellRange("A2").setValue("Linux");
        sheet.getCellRange("A3").setValue("Mac OS");

        piechart.setChartTitle("Users of System");
        piechart.getChartTitleArea().isBold(true);
        piechart.getChartTitleArea().setSize(12);

Excel Pie Chart

Create an exploded pie chart.

The following are the main steps to create an exploded pie chart. Exploded Pie chart is used to pull all of the slices out of a pie chart and view the sectors separately in pieces.

  • Create a Workbook instance.
  • Get a specified worksheet using Workbook.getWorksheets().get(sheetIndex) method.
  • Add some data to the worksheet and set values, styles and number format of the Excel cells.
  • Add an exploded pie chart to the worksheet using Worksheet.getCharts().add(ExcelChartType.PieExploded) method.
  • Set data range for the chart through Chart.setDataRange() method.
  • Set position, title for the chart.
  • Save the document to file using Workbook.saveToFile() method.

Exploded Pie Chart

Create a pie chart with one exploded slice

It is very similar with the circle chart. You only need to exploded one slices from the whole pie chart.

  • Create a Workbook instance.
  • Get a specified worksheet using Workbook.getWorksheets().get(sheetIndex) method.
  • Add some data to the worksheet and set values, styles and number format of the Excel cells.
  • Add a pie chart to the worksheet using Worksheet.getCharts().add(ExcelChartType.Pie) method.
  • Set data range for the chart through Chart.setDataRange() method.
  • Set position, title for the chart.
  • Exploded one specific slice from the whole pie chart using Chart.getSeries().get(0).getDataPoints().get(1).getDataFormat().setPercent(20) method.
  • Save the document to file using Workbook.saveToFile() method.

        cs.getDataPoints().getDefaultDataPoint().getDataLabels().hasValue(true);
        piechart.getPlotArea().getFill().setVisible(false);

        //Exploded the specific slice from the pie chart
        piechart.getSeries().get(0).getDataPoints().get(1).getDataFormat().setPercent(20);

        //Save the result file
        workbook.saveToFile("ExplodedPieChart2.xlsx", ExcelVersion.Version2016);

        ChartSerie cs = piechart.getSeries().get(0);
        cs.setCategoryLabels(sheet.getCellRange("A2:A5"));
        cs.setValues(sheet.getCellRange("B2:B5"));

Conclusion

In this article, we have demonstrated how to create pie chart in Excel in Java. Spire.XLS for Java also support to create column chart, scatter chart or line chart to Excel worksheets. You can check the Excel forum for more features to adding more chart types to Excel files.
