Thank you. I was able to modify the polling period and get the change I desired. Below is some investigative/entertaining information if it helps anyone else.
With the default polling period of 2000 ms (2 sec), I placed my cursor at each side of a single grid box and measured the width to be 16...
The graphs have a time horizon of roughly 8.5 minutes. I would like to be able to change this time span, e.g. to 30 seconds or 1 minute. Can this be done?
