BCB动态定义对象，如何使用？

[xjhwc]

scytb.hpp程序如下：

#pragma hdrstop

#include "scytb.h"
//---------------------------------------------------------------------------
#pragma package(smart_init)
#pragma link "base16"

#pragma resource "*.dfm"
Tscytb_Form *scytb_Form;

TLineSeries *series_sc;//定义一个全局的图表折线series
//---------------------------------------------------------------------------
__fastcall Tscytb_Form::Tscytb_Form(TComponent* Owner)
: Tbase16_Form(Owner)
{
}
//---------------------------------------------------------------------------
void __fastcall Tscytb_Form::FormCreate(TObject *Sender)
{
// 初始化
、、、、、
int i=0;
UQRY->First();
while (!UQRY->Eof)
{
//有多少机器，就有多少条折线
series_sc=new TLineSeries(this);
series_sc->Name="series_sc"+IntToStr(i);//折线名称有了
series_sc->ParentChart=DBChart1;
、、、、
DBChart1->AddSeries(series_sc);

i=i+1;
UQRY->Next();
}
}
//---------------------------------------------------------------------------
void __fastcall Tscytb_Form::BitBtn1Click(TObject *Sender)
{
//这里想用series_sc3，不知道该如何使用
}
//---------------------------------------------------------------------------

在DBChart中去找相应的series就行

[ccrun.com]

if (DBChart1->SeriesCount() > 2)
{
    DBChart1->Series[2]->Title = "123";
}
