help getting DAQ assist running right

[Anonymous]

to start off, i know very little about labview, and what i do know has
been from tinkering around for the past week or so.
i am doing a project where i am using 2 thermocouples and 3 pressure
transducers.
at first i made a DAQ assist module thing for each transducer (5 DAQ
assists) and began running into this resource reserved error. i looked
it up online and it kept talking about tasks and i didn't understand
what was going on. then i realized what the error was, and i changed
the thermocouples to 1 DAQ assist and the pressure transducers to
another DAQ assist so i was only working with 2 DAQ assists total.
this worked for a few trial runs and then began giving me the resource
reserved error again. then i finally put everything into one DAQ
assist and it works alright and outputs transposed data to a text file
correctly. the only problem is that in the VI window i want a chart/
graph for pressure and a chart/graph for temperature. right now they
are all on one chart/graph and you can't really get any information
from it because they pressures vary so much from the temperatures. how
can i set this up so that pressure is on one and temperature is on the
other?

Just sticking with the Express functions for simplicity, look in the Express>Signal Manipulation palette.

There's two functions in there that should get to where you want.

One is Split Signals. This is the simplest way. This node can be re-sized (by just clicking and dragging on the bottom) to output the number of signals you are reading from the DAQ assistant. The output order of this will be the same as the scan order you have setup in the DAQ assistant. You can use the Merge Signals to get the corresponding signals back into a single wire to connect to the graph or chart.

The other is Select Signals. This allows you to specify which signals to output so you end up with a single wire with all the signals you want for that graph/chart.

And just for informational purposes, all the analog inputs on a multi-function DAQ card (all M and E series cards) are a single resource. Kind of like a serial port. So you can only access any of the analog inputs from a single place in your application. This why using multiple ones wouldn't work.
