Thank you for your reply, I am very much a novice and appreciate your help.
When we first step in the VI it works through a sequence of setting various values and loading protocols later on in the set of sequences (Lower right). These values are loaded imdeiately. My understanding is that the VI executes this stack before anything else? Another problem, this is my first time working in a project and I am unable to trace?
the previous post contains some of troubleshooting... changing XScale.Format to "7" resolved the issue but now I'd like the chart to start at time 0 (i'd really rather have relative time)
Right click your chart from the front panel > properties > display format > relative time, and you can set the precision.
If one of your variables is Time, and you want Relative Time, simply take a Time reading at the beginning and subtract it from all of the other Time values. Note that the TimeStamp format is "special" and displays date and time, while subtracting them gives you "seconds" as a float.
P.S. -- I recommend, after reading this, that you re-post your VI. This is a test (to see if you read this, and are willing to take suggestions) ...
I was doing great until your P.S., thanks for the many suggestions... I have a lot of learning to do. BTW, that snippet thing is amazing and a good option in my case.
