increase data acquisition time on waveform graph of voltage

I pretty new to LabView and I am using a pressure transducer. I understand that using this will give me a voltage and I have calibrated it so I know the conversion of voltage to pressure.

 

After calibration I want to use it to measure the pressure through a pipe over a period of 5 seconds. However, I used DAQ assist and for the calibration it gave me perfect results over 1 second. I am using the same code but I am unable to increase the time scale of my graph from 1 second. If I increase the axes to 5 seconds, the graph stops at 1 second. My graph continously runs but after 1 second it reruns.

 

I would be very grateful if someone could help me record more than 5 seconds of results so that I can see the pressure changes. Thank you so much in advance.

Hi erfan,

 

collect the data from 5 consecutive seconds and display them in your graph! 😄

(It might be easier to request 5times the amount of data from your DAQmx task.)

 

Maybe you should attach your VI when you have problems with the VI!?

Best regards,
