No, the hyperlinks did not work.

1.  Attach image to e-mail by pasting in path where it is on your hard drive to the Attachments area below the message body window.
2.  Submit message.  You should see your message in the board with the attachment listed at the bottom.
3.  Edit your message from the options at the upper right.  (Note: you have a time limit of about 5-10 minutes before you won't be able to edit.)
4.  Your message will pop up for editing.
5.  Right click on your attached image and click properties.  Highlight and copy the hyperlink that shows up in the dialog box.  It should point to the forums.ni.com site.
6.  Put your cursor in your message body where you want the picture to go.  (If the picture is huge, please don't do this as it stretches the screen).
7.  Click the yellow image icon at the top of the message body window.  Paste the hyperlink from #5.  Hit Okay.
8.  Click submit again.

Now, back to your issue.  Are you sure your getting data out of the CIN node?  How many data points does it get on each iteration.  Is it a string of points or just a single one.  Put a probe on the array wire coming out of that and watch it during operation.  How many elements are in that array?  It's not clear whether you are getting an array of data points for one channel, or a single data point for multiple channels.  I first thought it was the former, but now I am wondering if it is the latter.

Perhaps a clearer idea of how many channels and how they are being acquired will help.  Now I'm not sure why you have the get XY values and waveform to XY values waveform VI's in there.  I think you are trying to do something with these VI's that are taking in the opposite direction of where you truly want to wind up.  What are you trying to do with those VI's, why did you put them in there to begin with?  You may still need to build arrays and use the shift register, but perhaps not on the waveforms and XY pairs as you are doing now.

Matthew, I'm not sure how the VI you attached relates.

That's because I got my threads mixed up.

What I did also assumes that you are only collecting 1 channel of data, which the code you wrote will only work for collecting one channel of data.  If you need to collect multiple channels of data, there is some modification required.

But we'll get there when you understand collecting one channel of data first.

Perhaps you want something like this.

Ignore the replace array subset function and random # generator.  That was just to create varying data.  This is a waveform chart.  It starts at 0.

Also, look at this link.  This may help.

And this link How to Set the Absolute Time and Date on the X Axis of a Chart in LabVIEW?
