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

        zgc.AxisChange()
    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.

Hi,

Try setting:

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

before calling AxisChange()

Hope this helps.
