Averaging uneven measurements by time with uneven numbers of measurements

In your first request for help you said, "How do I average the 
measurements by every 30 minutes?"  With 25000 readings over three 
days, it looks as if you are getting readings just about every 
second.

Okay, why don't you use the first reading as your initial weight, 
w0.  Then subtract each succeeding reading from that to obtain the 
amount of feed dispensed.  Now plot that value every 30 minutes.

If you are interested in the variation of feed dispensed over a 
half hour interval, that can be easily obtained by accummulating 
those half-hour readings.
