java 创建 powerpoint 图表-凯发线上登陆下载网址

本文将介绍如何使用spire.presentation for java在幻灯片上创建图表。该示例以最常见的柱形图为例。

import com.spire.presentation.*;
import com.spire.pdf.tables.table.*;
import com.spire.presentation.charts.*;
import com.spire.presentation.drawing.fillformattype;
import java.awt.geom.rectangle2d;
import java.lang.object;
public class createchart {
    public static void main(string[] args) throws exception {
        //实例化一个presentation对象
        presentation presentation = new presentation();
        //插入柱形图
        rectangle2d.double rect = new rectangle2d.double(40, 100, 550, 320);
        ichart chart = null;
        chart = presentation.getslides().get(0).getshapes().appendchart(charttype.column_clustered, rect);
        //添加表名
        chart.getcharttitle().gettextproperties().settext("销售报表");
        chart.getcharttitle().gettextproperties().iscentered(true);
        chart.getcharttitle().setheight(30);
        chart.hastitle(true);
        //创建后台数据表
        datatable datatable = new datatable();
        datatable.getcolumns().add(new datacolumn("销售额", datatypes.datatable_string));
        datatable.getcolumns().add(new datacolumn("谷物", datatypes.datatable_int));
        datatable.getcolumns().add(new datacolumn("粮油", datatypes.datatable_int));

        row1.setstring("销售额", "门店1");
        row1.setint("谷物", 250);
        row1.setint("粮油", 150);
        row1.setint("百货", 99);
        datarow row2 = datatable.newrow();
        row2.setstring("销售额", "门店2");
        row2.setint("谷物", 270);

        row3.setint("百货", 49);
        datarow row4 = datatable.newrow();
        row4.setstring("销售额", "门店4");
        row4.setint("谷物", 330);

        row4.setint("百货", 49);
        datarow row5 = datatable.newrow();
        row5.setstring("销售额", "门店5");
        row5.setint("谷物", 360);

        row5.setint("百货", 141);
        datarow row6 = datatable.newrow();
        row6.setstring("销售额", "门店6");
        row6.setint("谷物", 380);
        row6.setint("粮油", 150);
        row6.setint("百货", 135);
        datatable.getrows().add(row1);
        datatable.getrows().add(row2);
        datatable.getrows().add(row3);
        datatable.getrows().add(row4);
        datatable.getrows().add(row5);
        datatable.getrows().add(row6);
        //将数据写入图表
        for (int c = 0; c < datatable.getcolumns().size(); c  ) {
            chart.getchartdata().get(0, c).settext(datatable.getcolumns().get(c).getcolumnname());
        }
        for (int r = 0; r < datatable.getrows().size(); r  ) {
            object[] datas = datatable.getrows().get(r).getarraylist();
            for (int c = 0; c < datas.length; c  ) {
                chart.getchartdata().get(r   1, c).setvalue(datas[c]);
            }
        }
        //设置系列标签
        chart.getseries().setserieslabel(chart.getchartdata().get("b1", "d1"));
        //设置类别标签
        chart.getcategories().setcategorylabels(chart.getchartdata().get("a2", "a7"));
        //为各个系列赋值
