Alright, I am going to post what I got so far...

The reason I am doing the step ladder approach is because I am going to place the text boxes under the points on the X axis so the graph looks like its scrolling. The goal of this graph is to update every second with the updated information.

Im having trouble importing the T however, it keeps coming back to me with the error message, "cannot use a string "" as an integer."

As always, anytips or advice would be appreciated.

vb Code:
  1. Imports System.Windows.Forms.DataVisualization.Charting
  2.  
  3. Public Class Form2
  4.  
  5.     Dim chart1 As New Chart
  6.     Shared Property T As Integer
  7.  
  8.  
  9.     Private Sub Form2_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
  10.  
  11.     End Sub
  12.  
  13.     Private Sub TextBox11_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox10.TextChanged
  14.  
  15.         If T <= 2 Then
  16.             Label1.Visible = False
  17.  
  18.             TextBox20.Text = TextBox21.Text
  19.             TextBox31.Text = TextBox32.Text
  20.  
  21.             TextBox21.Text = TextBox22.Text
  22.             TextBox32.Text = TextBox33.Text
  23.  
  24.             TextBox22.Text = Form1.TextBox10.Text
  25.             TextBox33.Text = Form1.TextBox4.Text
  26.  
  27.             Dim s1() As Point = {New Point(T - 2, TextBox20.Text), New Point(T - 1, TextBox21.Text), New Point(T, TextBox22.Text)}
  28.             Dim s2() As Point = {New Point(T - 2, TextBox31.Text), New Point(T - 1, TextBox32.Text), New Point(T, TextBox33.Text)}
  29.             For x As Integer = T - 2 To T
  30.                 chart1.Series(0).Points.Add(x, s1(x).Y)
  31.             Next
  32.  
  33.             chart1.Series.Add("Series2")
  34.  
  35.             chart1.Series(0).ChartType = DataVisualization.Charting.SeriesChartType.Line
  36.             chart1.Series(1).ChartType = DataVisualization.Charting.SeriesChartType.Line
  37.  
  38.             For x As Integer = T - 2 To T
  39.                 chart1.Series(1).Points.Add(x, s1(x).Y)
  40.             Next
  41.             chart1.Series(0).Label = "PSS"
  42.             chart1.Series(1).Label = "USS"
  43.  
  44.  
  45.         End If
  46.     End Sub
  47.  
  48.     Private Sub Form2_FormClosing(ByVal sender As Object, ByVal e As System.Windows.Forms.FormClosingEventArgs) Handles Me.FormClosing
  49.         If Form1.CheckBox1.Checked Then Form1.CheckBox1.Checked = False
  50.     End Sub
  51.  
  52.  
  53. End Class
