How do i do the math for each hour, I'm really stuck as to how to add it all up to get a sensible figure. would it be the value at each sample (IE every second) added together 3600 times to give the Amp/hour value?
Perhaps the others have said enough already, anyway:
You've got readings of a current in amps every second. I think what you first want is the average current over the hour. So add up all the readings that hour, and divide by 3600. If some of the readings were missing for some reason, then add up those that you've got, and divide by the number of readings.
Having got average amps, then it's up to you what you then call the scale on your histogram. Just leave the number as it is, and calls it 'average current (amps)'. Or given that the period on your histogram is 1 hour, then plot the same number, but call it 'ampere hours (Ah)' - don't write "Amp/hour" - that looks like 'amps per hour' which is meaningless.
For a 'moving average', you do the same as above, but start your 'hour' at a different time, e.g. a minute later or whatever
