How do I make an XY-Graph plot points over time?

50 step values. Thanks for letting me know, just in time!

The current is not showing a constant value. You just have the scale of the Y axis too large to show the small values that you are reading. Change the precision and the scale to match your readings.

Ah yes! I took the Y-values off of autoscale and that's why I couldnt' read it. Now it works great. Thank you!

I was looking into combining the two columns of data I get as output so that way I could have one column for voltage, one for current. I tried the following (still using the individual outputs to verify) and got one large column with the correct voltage data and current data. My question is, how do I make this data into two columns so that I can read a column for voltage and a column for the corresponding current?

I have no idea what you are talking about. The only 'combination' you are doing is with the Build Array and you are definately not getting 'one large column'. You are getting two rows with multpile columns and to change that, all you have to do is transpose the array either before you pass the data or with the option of Write to Spreadsheet File.

Ah, I had the delimiter set to '\n' instead of '\t'. Changing it back to default, I get what you were talking about. Thanks!

I think I messed up the 'write to spreadsheet' VI. I have made indicators to check the values output and I am outputting the corect values, but the write to spreadsheet just outputs a file with zeros. I deleted it and put in another 'write to speadsheet' but I think this error has somehow been set to default and I don't know how to change it.

[Dennis_Knutson]

Seeing your previous post about changing the default terminator, tells me you modified the actual VI and did not make a copy. NEVER, EVER modify one of the VIs that ships with LabVIEW. I have no idea what modifications you may have made since you did not post the changed VI. Post the modified VI or do a repair on your LabVIEW installation.

It's the 'write to spreadsheet' VIs. I tried copying and pasting to the desktop, but that didn't work.

[Dennis_Knutson]

I ran a diff with what I have for Write to Spreadsheet and what you posted and there are no differences.

[nano3528]

I repaired the files and now the program works. I'm not sure what happened but I'll make copies of anything from now on. Thanks for the tip!
