real time graphing

[GSO]

I'm having an issue graphing the analog input in the attached vi.  My intention is to display the analog voltage in real time, every second or so for 60 to 120 seconds.  However, with the attached .vi, all i get is 1 second worth of data.  (I haven't used labview that much and any help would be greatly appreciated)  Thanks, in advance.

Sorry, I can´t see your vi because the version I use (8.6),

maybe somethings like this VI can help you.

What you are seeing is the behavior of a graph.  A graph shows only the data it was just given, it does not have a history.  But, charts do.

I suggest that you take a look at the example finder examples "Charts.vi" and "Real-Time Chart.vi".  These should get you started.
