ZedGraph图形更新问题

目前我没有使用它的控件，是直接引入了它的DLL，然后写代码实现柱图，
现在大概是这样写的



private void statisticForm_Load(object sender, EventArgs e)

{

    myPane = new GraphPane(new Rectangle(50, 70, 490, 375), "My Test",

    "My X Axis", "My Y Axis");

string[] labels = { "a", "b", "c", "d", "e", "f" };

                double[] y = { 100, 115, 75, 22, 98, 40 };

                double[] y2 = { 90, 100, 95, 35, 80, 35 };

                double[] y3 = { 80, 110, 65, 15, 54, 67 };

                double[] y4 = { 120, 125, 100, 40, 105, 75 };





                BarItem myBar = myPane.AddBar("Curve 1", null, value, Color.Red);

                myBar.Bar.Fill = new Fill(Color.Red, Color.White, Color.Red);



                //myBar = myPane.AddBar("Curve 2", null, y2, Color.Blue);

                //myBar.Bar.Fill = new Fill(Color.Blue, Color.White, Color.Blue);



                LineItem myCurve = myPane.AddCurve("Curve 4",

                        null, y4, Color.Black, SymbolType.Circle);

                myCurve.Line.Fill = new Fill(Color.White, Color.LightSkyBlue, -45F);



                myCurve.Symbol.Size = 8.0F;

                myCurve.Symbol.Fill = new Fill(Color.White);

                myCurve.Line.Width = 2.0F;



                //这两句是改变横坐标

                myPane.XAxis.Type = AxisType.Text;

                myPane.XAxis.Scale.TextLabels = labels;

                //改变柱图范围的背景色

                myPane.Chart.Fill = new Fill(Color.White, Color.FromArgb(255, 255, 166), 45.0f);



                myPane.YAxis.Color = Color.Red;

              myPane.AxisChange(this.CreateGraphics());  

}

private void statisticForm_Paint(object sender, PaintEventArgs e)

        {

            

            myPane.Draw(e.Graphics);

        }
