I want to make a graphic of certain data in my program. The problem is that the zedgraph doesn't zoom out to see the dots or lines in the graphic. This is my code:

Sub llenar_graph(ByVal zgc As ZedGraphControl)
        Dim myPane As GraphPane = zgc.GraphPane

        myPane.Title.Text = "Algoritmo Genético"
        myPane.XAxis.Title.Text = "Generación"
        myPane.YAxis.Title.Text = "Fx"

        Dim list1 As New PointPairList()
        For i = 0 To ngen
            list1.Add(i, promediofx(i))
        Next i

        Dim myCurve As LineItem = myPane.AddCurve("Mejor individuo", _
           list1, Color.Red, SymbolType.Default)
        myCurve.Line.IsVisible = True

    End Sub

I've tested the codes that Zedgraph provides in his homepage, but that code only work if you call this subroutine in the form load. Instead of that, I want to make the graphic when I clic a button. I don't have experience with VBNet, so please help.


Try setting:

myPane.YAxis.Scale.MinAuto = True
myPane.YAxis.Scale.MaxAuto = True

before calling AxisChange()

Hope this helps.
