Graphics in visual basic 2010

[patpaulj]

H, I began programming in visual basic few weeks ago and I am really getting along fast. I however want to plot two sets of values XY on a graph with logarithmic scale.I have created the arrays that stores the number as it is being inputed by the user using the inputbox. I have however not been able to scale the picturebox and also plot my desired graph. Anyhelp.... thanks

    Dim dataPoints As Integer
    Dim X(50) As Single
    Dim Y(50) As Single

   

 'To ensure that data entered do not exceed 50
     dataPoints = Integer.Parse(TextBox1.Text)
            If dataPoints > 50 Then
                MessageBox.Show("The data points chosen are too much for a typical well", "Excess data", MessageBoxButtons.OK, MessageBoxIcon.Error)
    
  

  'To enter the x values

        Try
            Dim k As Integer
            For k = 1 To dataPoints
                formFact(k) = InputBox(k)
            Next

        Catch ex As Exception
            MessageBox.Show("Enter only digits", "Invalid Input", MessageBoxButtons.OK, MessageBoxIcon.Warning)
        End Try


     

   'To enter Y values

        Try
            Dim k As Integer
            For k = 1 To dataPoints
                formFact(k) = InputBox(k)
            Next

        Catch ex As Exception
            MessageBox.Show("Enter only digits", "Invalid Input", MessageBoxButtons.OK, MessageBoxIcon.Warning)
        End Try
