在线等。急！急！

TChart *cht1 ;
cht1 = new TChart(this);
cht1->Top = 0;
cht1->Left = 0;
cht1->Height = 300;
cht1->Width = 300;
cht1->Parent = this;

我是说创建多个TChart图形，如何实现？谢谢！

[zzbinfo]

你说的是不是这个呀

TAreaSeries *series = new TAreaSeries(NULL);
 series->Add(2,"测试",TColor(123,123,4));
// series->Add(3,"测试",TColor(123,123,4));
 series->Add(4,"测试",TColor(123,123,4));
// series->AddNull("asd");
/*TChartSeries *series = new TChartSeries(NULL);
 series->Add(2,"测试",TColor(123,123,4));
 */


cht1->AddSeries(series);

我是说创建多个TChart图形，如何实现？

下面創建 n 个TChart图形 :
for(int i= 0 ; i < n ; ++i)
{
TChart *cht = new TChart(this);
cht1->Parent = this;
}

我是想說，樓主問題描述不夠明確，想幫你的人不好下手。
