collecting data from NI devices (Session based)

I have a general question. Is there a way to collect data from only ONE channle in a session based data acquisition format from NI devices (assuming that you have multiple channels added to the same session.

For example:

s = daq.createSession('ni');

now when i use either methods for collecting data

Matlab collects the data from all channels. I would like to know if it is possible to collect the data only from one channel at a time. I would also like to know if I can use 'peekdata' to update a graph that plots data acquired from that single channel (and updates the graph instead of replacing with new data as with using a listener).

Any help or ideas would be greatly appreciated.
