Proform 850 dialing it in closer

I need to make a couple pass, logged before i do anything, i think.
could sure us your help being able to post my results.
If i saved my garage log to a "csv" i can open it up in Excel, as a spread sheet but have no clue how to get It back to a graph................. like above
lets see if this works. had to change it from csv file to PDF.....
I revved it in neutral until the the gas flowing was high enough to start reading the sensor properly.
