Hi, I would like to make a graph displaying 2 plots. Plot (a) reads an incrementing integer on y-axis vs time on x-axis Plot (b) shows the difference of the previous value that has occurred between lets say every 15 min of an hr I want the x-axis showing the live time in “HH:mm” format constantly updating every hr as I would like to separate the x-axis in lets say 4 slots (every 15 min). finally is there a way to store those graphs somewhere? ---

How are you storing the values? Tag History? From a database? ---

I am reading values from the PLC so the tag is stored in Tag History indeed.
