Hello
I have got data form last 4 days and plot looks like that (data is collected every ~5 or 6 mins)
When I download that data and calculate average for each day it is:
06.10->159,9
05.10->138,3
04.10->149,2
03.10->143,3
But when I use statistic graphs i got those values:
Why there are differences? how its calculated? and what I co do to improve that?
