I would like to ask you, whether you kbow how to calculate from Graph the area - especially ingral of the area
I have graph from my measurement and there are on the X axis - time from midnight to midnight, and on the Y axis there are litres per seconds.
So I need calculate integral of the area ( see picture below) - from 0:00 to 0:00 and obtain the number of cubic meters.
I don´t know if I have to calculate integral of this area or the number of cubic meters I obtain some other way - some shortcut.
Thank you for any advice
