how to disable autoscale in "y" and "X" axis using zedgraph control

Im using zedgraph control to make a graph with visual basic

This is the code:

Imports ZedGraph
Public Class Form1
    Private Sub CreateGraph(ByVal zgc As ZedGraphControl)
        Dim myPane As GraphPane = zgc.GraphPane
        myPane.Title.Text = "My Test Graph"
        Dim list1 As New PointPairList()
        Dim i As Integer, x As Double, y1 As Double
        For x = 0 To 46000 Step 100
            y1 = 1.5 + Math.Sin(i * 0.2)
            list1.Add(x, y1)
        Next

        Dim myCurve As LineItem = myPane.AddCurve("Porsche", list1, Color.Red, SymbolType.Diamond)
        zgc.AxisChange()
        zgc.Refresh()
    End Sub

    Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        CreateGraph(grafica_entrada)
    End Sub
End Class

Select allOpen in new window

And this is the result:

As you can see both axis start with a scale.

I would like to know if it is possible that when the project load the axis remains without scale
