the daq assistant returns data using the dynamic data type.&nbsp; I would convert the dynamic data type to an array of waveforms.&nbsp; Then you can index the first element (channel) and put in on one graph, index the second element and put it on another graph.&nbsp;&nbsp;<img src="http://forums.ni.com/ni/attachments/ni/170/349620/1/diagram.PNG" border="0" width="416" height="186"> The convert from dynamic data function is under the express pallet &gt; signal manipulationMessage Edited by StevenA on 08-15-2008 09:18 AM

I would suggest using the &quot;Split Signal&quot; functionIt is located:Express &gt;&gt; Signal Manip &gt;&gt; Split Signal&nbsp;Wire the output of your DAQ assistant to the split singal.Then the two outputs of that function will be voltage, and current.Then you can do whatever you want with each one.
&nbsp;Split signal works too :smileyhappy:

Ok, if I add a Split Signal function, I can right click on the top output and I get the option of adding a graph which I do and I get my voltage waveform alone, which is what I'm looking for.&nbsp; But when I right click on the next output, it seems to have no waveform associated with it.&nbsp;Randy&nbsp;
I'm seeing the same thing with the split signals...this should work, I'm not sure why?&nbsp; Using my method where you convert to waveform data type will work.&nbsp;
