is it possible to export a graph to a file? And is it possible to view (and export) a graph for a specific time, maybe a complete day? When using the normal graph it shows last 24h, but I want to see a complete day from 0:00 to 23:59. Or even a graph for monday 0:00 to sunday 23:59. That would be great. If it’s not possible from gui, maybe there is a way to read those values from the database, draw a graph and export.
I have several DS18B20 reading the temperatur of a heating system and want to have comparable graphics.
