效果图： 代码如下： //绘制二维坐标 private void button_DrawCoordinate_Click(object sender, EventArgs e) //绘制坐标系 { Graphics g = CreateGraphics(); Pen m_pen = new Pen(Color.Black,2); Pen m_pen1 = new Pen(Color.FromArgb(101, 189, 101), 1); Brush m_brush = new SolidBrush(Color.FromArgb(51,119,51)); int x = 30; int y = 30; g.DrawRectangle(m_pen,x,y,700,300); g.FillRectangle(m_brush, x+1,y+1,698,298); for (int i = 0; i < 6; i++) { string draw_str = string.Format("{0}", 6000 - 1000 * i); //画刻度 g.DrawString(draw_str, this.Font, Brushes.Black, new Point(2, y-5)); y += 50;
