  private void DrawBar()
        {
            try
            {
                Graphics myG = this.CreateGraphics();
                myG.Clear(Color.White);
                Pen pen = new Pen(Color.Black);
                pen.EndCap = LineCap.ArrowAnchor;
                pen.DashStyle = DashStyle.Solid;                //画坐标
                Point pCenter = new Point(300, 350);
                //x
                myG.DrawLine(pen, new Point(pCenter.X - 200, pCenter.Y), new Point(pCenter.X + 100, pCenter.Y));
                myG.DrawString("x", new Font("宋体", 9), Brushes.Black, new Point(pCenter.X + 103, pCenter.Y));
                //y  
                myG.DrawLine(pen, new Point(pCenter.X - 200, pCenter.Y), new Point(pCenter.X - 200, pCenter.Y - 175));
                myG.DrawString("y", new Font("宋体", 9), Brushes.Black, new Point(pCenter.X - 210, pCenter.Y - 175));
                //画X轴上的表格
                for (int i = 0; i < 10; i++)
                {
                    myG.DrawLine(Pens.Black, new Point((pCenter.X - 200) + 25 * (i + 1), pCenter.Y), new Point((pCenter.X - 200) + 25 * (i + 1), pCenter.Y - 5));//x
