关于Tdbchart 的使用

Question

那位朋友有关于Tdbchart 的详资料。帮帮忙！！！

Answer 1

只能告诉你，看Delphi下的Demo和帮助文件吧。很难找

Answer 2

给你点我的例子吧
procedure  tchartform.getbar(x,y:string);
var series1:tbarseries;
begin
  series1:=tbarseries.Create(self);
  series1.ParentChart:=dbchart1;
  series1.DataSource:=dbset;
  series1.XLabelsSource:=x;
  series1.yValues.ValueSource:=y;
  series1.Title:=x;
 // series1.XLabelsSource:
  series1.Active:=true;
  dbchart1.BottomAxis.Title.caption:=x;
  dbchart1.leftAxis.Title.caption:=y;
  dbchart1.leftAxis.Title.Angle:=0;
end;procedure  tchartform.getpie(x,y:string);
var series1:tpieseries;
    i:integer;
begin
  series1:=tpieseries.Create(self);
  series1.ParentChart:=dbchart1;
  series1.DataSource:=dbset;
  series1.PieValues.ValueSource:=x;
  series1.XLabelsSource:=y;
  
 // for i:=1 to series1.Labels.Count do
   //  series1.Labels.Items[i]:=
  // series1.PieValues.Sort;
//  series1.yValues.ValueSource:=y;  dbchart1.Title.Text.Text:=datfm.caption;
  series1.Active:=true;
end;
其中有的变量你猜都猜得出来是什么，比如dbset就是一个tdataset
