Cavas画图问题，简单！

[JIANDAN_2002]

在Image中画一坐标系，如何画出x,y轴的刻度，是否用短线来画？如何将刻度数值打在旁边？不胜感激！

还不如用TChart。

void __fastcall TForm1::Button1Click(TObject *Sender)
{
Image1->Canvas->MoveTo(0,100);
Image1->Canvas->LineTo(400,100);
for(int i=0;i<400;i+=20)
{
Image1->Canvas->MoveTo(i,100);
Image1->Canvas->LineTo(i,95);
Image1->Canvas->TextOutA(i,105,i/10);
}
}
再结尾用canvas->polygon绘出箭头就好了
