the best way to do this would be to create the basic graph in Excel, use Excel'S COM to update the graph dynamically according to your input, and view the updated graph in an OLE container on your VB app.

Do you know the range of data you will get before hand, or will we have to figure mins and maxs as we go?

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

I thought I might have some code on tap, but it looks too complicated with extraneous computations to post here.  Basically, what I do is calculate a max X and Y value from my data set, then scale it into a picture box.  Clear the picture box on each pass and use picture.line to draw the line from data point to data point.

I answered a question like this last year, but I can't find it now.  Probably a question with a silly name, :( ("Calling all Experts" or something.)

mishbal, you should probably delete this question as I think it is related to the one that I answered for you subsequently. Or if you wish award the points to the expert that you feel helped you the most.
