Calculated Metric Function: Count Items. For averages (e.g. Visitors per month) and more

[#1]

A function within calculated metrics which gives the ability to use the number of a specific item. See mocked-up screenshots below for example. As far as I can tell this doesn't exist now? Correct me if I am wrong.

Practical uses (I can think of so many company-specific uses but they will be meaningless so here are a few generic ones)

1) Unique Visitors / Counted months

2) Show number of countries visiting each page

Product Page	Counted countries	Revenue per Country
Product A	67	4,123
Product B	22	6,060
Product C	101	1,111

3) Show volume of different pages viewed each day to spot trends

Day	Pages counted (i.e. viewed)
Jan 1st	121
Jan 2nd	111
Jan 3rd	100
etc.

This expands on the idea here: Time units in Calculated Metrics

Good news!  We actually released this last year - there is a function in the Calculated Metric Builder called "Approximate Count Distinct", and it works exactly like you've diagramed - it takes a dimension, and gives you a count of the unique number of items for that dimension.

Brilliant - thanks Brandon.

Hi Brandon,

Is there any movement towards removing the "approximate" to have an exact count? The numbers are off by 1,000+ in my dashboard when I use approx. count distinct vs looking at the number of rows.
