Hi all as the title suggests i would like to display the weekly daily energy usage into a waveform chart. I have in my VI a daily log file creator ( referenced from this article https://forums.ni.com/t5/LabVIEW/Automatic-save-and-create-new-file-everyday/td-p/3608974) in my "Write While Loop".
My Modbus power meter's energy reading is cumulative but i am just artificially creating values for this vi.
In my VI's "Read While Loop" how can i let it automatically read the past seven day's TDMS log files and extract the energy usage of the day("last energy value of the log" - "first energy value of the log" = energy usage for the day) and plot them into a waveform chart?
