C＃WindowsFormsApplicationは、座標に基づいて単純な線図を描画します

Point[] pot = { new Point(0, 123), new Point(50, 148), new Point(100, 118), new Point(150, 192), new Point(200, 176), 
                      new Point(250, 237), new Point(300, 320), new Point(350, 450), new Point(400, 219), new Point(450, 180), new Point(500, 170)};
        private void Form1_Paint()
        {
            Graphics gobj = this.CreateGraphics();
            gobj.DrawCurve(new Pen(Color.Blue, 2), pot, 0f);//数据间连曲线
            gobj.Dispose();
        }

private void button2_Click(object sender, EventArgs e)
        {
            Form1_Paint();
        }
