Which DAQ card are you using??
If it is supported by DAQmx device drivers, In LabVIEW Find Examples>>Hardware input&output>>DAQmx>>Analog measurements>> Voltage folder, you will find two example vi's
'Cont Acq&Graph Voltage-To File(Binary).vi' which will acquire data and save it to a file in binary format
'Graph Acquired Binary Data.vi' which reads and displays the binary file created in the above mentioned vi.
Hope this helps
Regards,
Dev
