各位高手，请问在VC#.net中画函数曲线怎么做

[qinglu]

Graphics g=new Graphics();
g.drawling(new Pen(Color.white,3),Point0,Point1);
函数两点之间的坐标如何确定？？

[panyee]

e.Graphics.DrawBezier(pen, pt1, pt2, pt3, pt4);

[panyee]

private void Form5_Paint(object sender, System.Windows.Forms.PaintEventArgs e)
{
Graphics g = e.Graphics;
g.DrawLine(new Pen(Color.White, 3), new Point(100, 200), new Point(20, 10));
}
