Hi Krishnna,

Assuming you are using LabVIEW and DAQmx, I would advise you to use the DAQ assistant and the Waveform graph.  When you place a DAQ assistant onto the block diagram you set it up for one channel.  Once you get thru the setup menu you can change the "Acquisition Mode" to Continuous Samples.  You can also add the other 6 channels in the channel settings section. 

Place a waveform graph onto the front panel.  Move the graph indicator into the while loop and connect it to the data output of the DAQ assistant.  This will allow you to plot all 7 AI channels on the same graph.
