Delphi控制Excel的经验(二) 分享
(三) 使用Delphi 控制Excle二维图
在Form中分别放入ExcelApplication, ExcelWorkbook和ExcelWorksheet
var asheet1,achart, range:variant;
1）选择当第一个工作薄第一个工作表
asheet1:=ExcelApplication1.Workbooks[1].Worksheets[1];
2）增加一个二维图
achart:=asheet1.chartobjects.add(100,100,200,200);
3）选择二维图的形态
achart.chart.charttype:=4;
4）给二维图赋值
series:=achart.chart.seriescollection;
range:=sheet1!r2c3:r3c9;
series.add(range,true);
5）加上二维图的标题
achart.Chart.HasTitle:=True;
achart.Chart.ChartTitle.Characters.Text:=’ Excle二维图’
6）改变二维图的标题字体大小
achart.Chart.ChartTitle.Font.size:=6;
7）给二维图加下标说明
achart.Chart.Axes(xlCategory, xlPrimary).HasTitle := True;
achart.Chart.Axes(xlCategory, xlPrimary).AxisTitle.Characters.Text := '下标说明';
8）给二维图加左标说明
achart.Chart.Axes(xlValue, xlPrimary).HasTitle := True;
achart.Chart.Axes(xlValue, xlPrimary).AxisTitle.Characters.Text := '左标说明';
9）给二维图加右标说明
achart.Chart.Axes(xlValue, xlSecondary).HasTitle := True;
achart.Chart.Axes(xlValue, xlSecondary).AxisTitle.Characters.Text := '右标说明';
10）改变二维图的显示区大小
achart.Chart.PlotArea.Left := 5;
achart.Chart.PlotArea.Width := 223;
achart.Chart.PlotArea.Height := 108;
11）给二维图坐标轴加上说明
achart.chart.seriescollection[1].NAME:='坐标轴说明';

以上是怎么不用空间而调用EXCEL的
很方便的！
