Пользовательский график ZedGraph

Я хочу сделать с помощью ZedGraph динамическую диаграмму: Как заставить оси ZedGraph перевернуться и по оси времени? Спасибо

UPD 1: Надо попробовать со следующим кодом:

GraphPane myPane = zg1.GraphPane;
            myPane.YAxis.Type = AxisType.Date;
            myPane.YAxis.Scale.MajorUnit = DateUnit.Minute;
            myPane.YAxis.Scale.MinorUnit = DateUnit.Second;
            myPane.XAxis.IsVisible = false;
            myPane.X2Axis.IsVisible = true;
            myPane.X2Axis.MajorGrid.IsVisible = true;
            myPane.X2Axis.Scale.Min = 0;
            myPane.X2Axis.Scale.Max = 600;
            myPane.YAxis.Scale.Format = "HH:mm:ss";
            PointPairList list = new PointPairList();
            PointPairList list2 = new PointPairList();
            for (int i = 0; i < 36; i++)
            {
                double x = (double)i * 5.0;
                double y = (double)new XDate(DateTime.Now.AddSeconds(i));
                list.Add(y, x);
                //list2.Add(y2, x);
                listBox1.Items.Add("x = " + x + " y = " + y);
            }

            // Generate a red curve with diamond symbols, and "Alpha" in the legend
            LineItem myCurve = myPane.AddCurve("Alpha",
                list, Color.Red, SymbolType.None);
            // Fill the symbols with white
            myCurve.Symbol.Fill = new Fill(Color.White);
                        myPane.Y2Axis.MajorGrid.IsVisible = true;
            // Align the Y2 axis labels so they are flush to the axis
            myPane.Y2Axis.Scale.Align = AlignP.Inside;

            // Fill the axis background with a gradient
            myPane.Chart.Fill = new Fill(Color.White, Color.LightGray, 45.0f);
            zg1.IsShowPointValues = true;
            zg1.AxisChange();
            // Make sure the Graph gets redrawn
            zg1.Invalidate();

Но я что-то не так понимаю:

UPD2:

У меня есть код для многопоточности:

private TimerCallback ReadTimerCallback;
        private LineItem myCurve;
        private Random rnd = new Random(500);
        public Form1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            GraphPane myPane = zg1.GraphPane;

            myPane.XAxis.IsVisible = false;

            myPane.X2Axis.IsVisible = true;
            myPane.X2Axis.MajorGrid.IsVisible = true;
            myPane.X2Axis.Scale.Min = 0;
            myPane.X2Axis.Scale.Max = 600;

            myPane.YAxis.IsVisible = false;

            myPane.Y2Axis.IsVisible = true;
            myPane.Y2Axis.Scale.MajorUnit = DateUnit.Minute;
            myPane.Y2Axis.Scale.MinorUnit = DateUnit.Second;
            myPane.Y2Axis.Scale.Format = "HH:mm:ss";
            myPane.Y2Axis.Type = AxisType.DateAsOrdinal;

            // As we get more data we want to add it on to the end of the curve
            // and we also want to get the scale so that we can shift it along
            double? oringinalLastDate;
            XDate firstDate;
            if (myPane.CurveList.Count == 0)
            {
                myCurve = myPane.AddCurve("Alpha",
                                          new PointPairList(),
                                          Color.Red,
                                          SymbolType.None);
                firstDate = new XDate(DateTime.Now);
                oringinalLastDate = null;
            }
            else
            {
                myCurve = (LineItem)myPane.CurveList[0];
                firstDate = myCurve.Points[myCurve.Points.Count - 1].Y;
                oringinalLastDate = myPane.Y2Axis.Scale.Max;
            }

            /*for (int i = 0; i < 36; i++)
            {
                double x = i * 5.0;
                firstDate.AddSeconds(i);

                myCurve.AddPoint(x, firstDate);

                //listBox1.Items.Add("x = " + x + " y = " + firstDate);
            }*/

            myCurve.Symbol.Fill = new Fill(Color.White);
            myCurve.IsX2Axis = true;
            myCurve.IsY2Axis = true;
            //myPane.Y2Axis.Scale.IsReverse = true;

            myPane.Chart.Fill = new Fill(Color.White, Color.LightGray, 45.0f);
            zg1.IsShowPointValues = true;

            // Now make the minimum of the scale, the maximum that it was so
            // the graph shifts
            if (oringinalLastDate.HasValue)
                myPane.Y2Axis.Scale.Min = oringinalLastDate.Value;

            zg1.AxisChange();
            zg1.Invalidate();
            AutoResetEvent ReadautoEvent = new AutoResetEvent(false);
            ReadTimerCallback = new TimerCallback(this.ShowData);
            System.Threading.Timer timer = new System.Threading.Timer(ReadTimerCallback, ReadautoEvent, 100, 1000);

        }

        private void ShowData (object Object )
        {
            this.myCurve.AddPoint(rnd.Next(500, 600), new XDate(DateTime.Now));
        }

UPD3: Я хочу двигаться вниз по оси Y, а не масштабировать эту ось. И я обновил график только за 1 минуту:
