TeeChart使用范例

在窗体上加入TeeChart控件，并通过属性加入4个TLineSeries，分别命名为Series1,Series2,Series3,Series4,并添加一按钮Button1,其Click事件为:

procedure TForm1.Button1Click(Sender:TObject);

begin

Series1.FillSampleValues(200);

Series2.FillSampleValues(200);

Series3.FillSampleValues(200);

Series4.FillSampleValues(200);

with chart1.LeftAxis do

begin

startPosition :=0;

EndPosition :=25;

Axis.Color:=clRed;

end;

Axis1 :=TChartAxis.Create(Chart1);

with Axis1 do

begin

startPosition :=25;

EndPosition :=50;

Axis.Color :=clGreen;

end;

Series2.CustomVertAxis :=Axis1;

Axis2 :=TChartAxis.Create(chart1);

with Axis2 do

begin

startPosition :=50;

EndPosition :=75;

Axis.Color :=clBlue;

end;

Series3.CustomVertAxis :=Axis2;

Axis3 :=TChartAxis.Create(chart1);

with Axis3 do

begin

startPosition :=75;

EndPosition :=100;

Axis.Color :=clYellow;

end;

Series4.CustomVertAxis :=Axis3;

end;

TSeries.Mark属性，为每个Series point的提示，可以为预定义值，如：smsLabelValue(顶点值)

TSeries.Title为右边标签框中的文本

TSeries.Legend为容纳TSeries.Title的容器
