Hello,  
  This is stumping me and I'm sure it is becuase I don't really have a grasp on what the different formats are. 
Basically I have a string of Data coming in from a GPIB device.  The comma seperated data can be of arbitrary length and is of the form: 
x1,y1,x2,y2,........ 
which I can read just fine. 
I'd like to make that into a cluster so I can plot it on an XY graph. 
What I tried to do is use "spreadsheet string to array" to make a 2D array, then index array to pull out row 0 and row 1, then use the bundle command to create an xy cluster. 
Any ideas?  Is it possible that some of the data in the form  1.000e-4  or similar is causing a problem? 
Thanks,  
Andrew
