Hi,
I have set up a DAQ application receiving 8 analog signals. I am using the 'Write to Measurment.VI'to log the data aquired but there doesnt seem to be as much capabilities in the form of the .txt. created.
more explicitely:
-How can i define or wire in the block diagram the X-axis as i wantit to be (count, time -relevant/absolute- etc)
-I dontknow how to NAME the signal so that in the header there is the signal name in each column instead of "untitled 1, untilted 2" etc.
- Is there i VI that ignors the header and uses the columns after the aquisition for further usage.
I am using a measurmetn Compoting board with Universal Library's VIs if that affects it in anyway.
thnx in advance

That clarifies at least the result that you don't want to have.
Could post a screenshot of the code that generated this result and if an Express VI is used the configuration page of the Express VI?

U're right. Well this is a screenshot of the Help topic for the express vi used in this case, The red framed paragraph refers to my problem.
What i understand is that all my signals are by default named "untitled" and this .vi adds numbers to them. I've tried to find another .vi that could rename my signal, but waht i've found out is that suck task is handled with MAX, which -unfortunately- colaborates with NI boards only.
So, could there be a .vi that renames signals??
..any idea coulb be helpful

I don't know why you would post the help topic instead of an image of your code like you were asked.
In any case, you can easily assign names to channels. You could simply use the Write to Text file and Write to Spreadsheet functions. You could also assign attributes to waveform data types and keep the express VI as shown here.
