Zedgraph Magnitude task in X2Axis in vb.net or C #

I have a hard time trying to get an excel half-log plot using zedgraph:

I currently have:

For this I have

Dim pane As New GraphPane()
'reverse order
pane.X2Axis.IsVisible = True
pane.XAxis.IsVisible = False
pane.YAxis.Scale.IsReverse = True
pane.YAxis.Scale.IsPreventLabelOverlap = True
' log type
pane.X2Axis.Type = AxisType.Log
pane.AxisChange()
' the y axis scale
pane.YAxis.Scale.Min = -20
pane.YAxis.Scale.Max = 120
'here I tried to manipulat x axis but had no success 

'the data

            Dim list As New PointPairList()
            Dim list2 As New PointPairList()        
            list.Add(0, 0)
            list.Add(125, 0)
            list.Add(250, 0)
            list.Add(500, 5)
            list.Add(750, 5)
            list.Add(1000, 10)
            list.Add(1500, 10)
            list.Add(2000, 5)
            list.Add(3000, 10)
            list.Add(4000, 10)
            list.Add(6000, 10)
            list.Add(8000, 20)
            list2.Add(125, 30)
            list2.Add(500, 30)
            list2.Add(750, 40)
            list2.Add(1000, 50)
            list2.Add(1500, 65)
            list2.Add(2000, 65)
            list2.Add(3000, 70)
            list2.Add(4000, 80)
            list2.Add(6000, 90)
            list2.Add(8000, 100)
            Dim myCurve As LineItem = pane.AddCurve("Series 1", list, Color.Blue, SymbolType.Diamond)
            Dim myCurve2 As LineItem = pane.AddCurve("Series 2", list2, Color.Magenta, SymbolType.Square)

As you can see, the data with x2 = 125, 250, 500, 750, 1 is not like the EXCEL Semi Log graph, since the zedgraph numbers are really small. Only in this part ....

How to get the desired excel graph using zedgraph? Is there a way to scale only that part or something else? Why does he appear 10^-1, 10^0 ,10^1? and not10^2, 10^3 10^4
