How do I draw a single scrolling multipage graph in VB/WPF

Hi everyone,

I have searched for an answer to this question for some time. After returning to some very good, somewhat related, Q&A here on Code Project, I thought I would finally post here and cross my fingers for a suitable answer.

I am recently returning to some amateur coding using VB+WPF after a 10 year hiatus and coming from Delphi/Pascal background.

I will use a very simplified example of what I am trying to implement. What I need is essentially a scrolling vertical graph. This needs to be a consistent page(not broken into pages like a word processor). Lets say the height of the screen would represent 60 min, but the document itself may scroll for days worth of data. This application would also have some whitespace to either side of this scaled graph that may have the user input text comments into a movable text box(each comment in a separate text box, that is separately aligned with a given time).There may be a few other graphical elements along this graph as well that user can click/add.

My problem here is that I am absolutely lost on where to start with this. I am thoroughly confused by how to properly draw this scrolling graph so that it is many many pages long. redrawing the data elements with each move up or down does not seem like the solution to me. I am absolutely stuck on this. I can implement all sorts of standard things that are static and limited to what I see on the screen. I recently did a nice cubic spline on a graphic module. But again, none of those lines leave the page. ANY help that is offered will be very much appreciated. I would love to see some simple code showing a long scrolling page with shapes/lines/text. At the moment, I am convinced it would be much easier to draw a scene in 3D than to try an get this understood.

Thanks in advance and I will be watching to answer any questions asked.

Mark
