Anyone used a plot function???

Hi all
I am trying to figure out how to plot a graph. I allready know how to do a TREND ( from right to left across the picture box) but I now need to find out how to do a plot from left to right, where you are able to see the plot building up as the inputs come in.

I hope you can understand what I am trying to do.:p

This should work

VB Code:

Dim X As Integer
Dim Y As Integer
 
For X = 0 To Picture1.ScaleWidth
    For Y = 0 To Picture1.ScaleHeight
        SetPixelV Picture1.hDC, X, Y, vbBlack 'from left to right
        SetPixelV Picture1.hDC, Picture1.ScaleWidth - X, Y, vbBlack 'from right to left
    Next
Next

btw...
that code fills the picture, but the main thing is the Picture1.ScaleWidth - X code that does the same thing, but backwards
