import java.awt.*;

public class addPictureToChart {
    public static void main(String[] args) {

        //加载示例文档
        Workbook workbook = new Workbook();
        workbook.loadFromFile("Sample.xlsx");

        //获取第一个工作表
        Worksheet sheet = workbook.getWorksheets().get(0);

        //获取第一个图表
        Chart chart = sheet.getCharts().get(0);

        //插入图表并设置样式
        IShape picture = chart.getShapes().addPicture("48.png");
        ((IPictureShape) picture).getLine().setDashStyle(ShapeDashLineStyleType.DashDotDot);
        ((IPictureShape) picture).getLine().setForeColor(Color.blue);

         //保存文档
        String result = "output/AddPictureToChart.xlsx";
        workbook.saveToFile(result, ExcelVersion.Version2010);
