Hi, 

Scale function is not working. Can you please give me how to use scale function or is there any other way to streach only chart.

Hi,

First Place a track bar in you form namely scalechart

then set the maximum=100 and minimum=0 in the track bar properties

 Private Sub Scalechart_ValueChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles Scalechart.ValueChanged
        FormGraph.ScaleChart = Scalechart.Value
    End Sub

 Hi 

And also write this functions

 Public Property ScaleChart() As Single

        Get
            Return Me.UltraChart1.Transform3D.Scale
        End Get
        Set(ByVal value As Single)
         
            Me.UltraChart1.Transform3D.Scale = value
                   End Set
    End Property

 In short i have to set UltraChart1.Transform3D.Scale properties. I have solved the problem. Thanks dear.
