A data stream is averaging data with a set frequency (every day) for a number of cities. Example:
Chi, 10, 20, 30, 9, 15,
Dal: 5, 6, 9, 10,...
Hous: 4, 7, 9, 2, ...
I create a simple pivot table where the "avg()" of each date series (per city) is done. To get pivot table like this:
City
Avg(avgSample)
Chi
5
Dal
11
Hous
20
Ques 1: what is the expression for having the above pivot. I can do that but please keep this in mind for the next question, as it is cause of my challenge.
Question 2: I want to count the cities which have Avg(avgSample) less than different thresholds: 10, 20, 30, 40.
Lastly, I want to get a Pie Chart. Showing what is the percentage of cities with thresholds of Avg(avgSample) less than 10, 20, 30, 40. I can use the pie chart for drawing this but...the above two questions are show stoppers.
