I use the available aggregation function Average to calculate an average production rate on a weekly basis. Is there a function or formulae to do the same thing meaning to measeare the standard deviation on a weekly basis. Also would like to use the same function for different aggregation time span week, month, year.

Also if possible would like to see both lines (average and standard deviation) on the same graph.
