Real time chart with finite acquisition

[Ech101]

I think this is a relatively simple question but it keeps throwing me the Error -200278, where it tries to sample a point that is not acquired. The solution says that I should be using continious acquistions but I only want to sample for a specific time. I am using a CompactDaq with 9234. However I want to have a real time chart, which is why I am using the while loop. Does anyone have a suggestions? Have attached vi

Probably the best place to start is the Labview Example Finder, Navigate to Help>>Find Examples. 

I would suggest looking at Acc&Graph Voltage-Int Clk-SW Trig Restarts.vi.

This VI shows how to acquire a finite amount of data fusing the DAQ internal Clock when a software trigger is enabled. Other examples look at how to apply a hardware trigger if that is something you specifically needed.

This example should allow you to get your finite number of samples, have them update periodically on the graph and determine when the acquisition will start.

Any questions or issue let me know.
