I'm not sure how your invalidating your form but if your invalidating the entire area everytime the dynamic rectangle is resized then you will see a performance hit.

     TimewayChartControl.RenderLinePath();        <-----draw line<br />

    bg.Graphics.TextRenderingHint = TextRenderingHint.AntiAlias;<br />
    bg.Graphics.Clear(this.BackColor);<br />
}

private void DrawLinePath(Graphics g)<br />
{<br />
    //some coding here.....<br />
    g.DrawPath(LinePathPen, gpLine);<br />

protected override void OnPaint(PaintEventArgs pe)<br />

   //draw the image into the screen<br />
   bg.Render(pe.Graphics);<br />
}
