Its work Fine But I want to be sure that is Right . 10x for the help
AzeoTech Posted September 1, 2011 Posted September 1, 2011 "ph_one" is the name of your channel? Then you want ph_one[0]. [0] means the most recent data point. [1] like you gave in your example means the next most recent data point.
