Calculating Average in Calc View

Hi,

I am trying to create a graphical calculation view using the following data to calculate average of the “Value” column for each “TYPE_NAME”:

Table:

Steps I performed

1. Created a simple analytic view using the above table.
2. I created a calculation view with a counter.
3. In calculation view, I have  1. Analytic View 2. Projection 3. Output
4. In Output, I have added TYPE_NAME as attribute and VALUE as measure. Created a new counter “COUNTER_ONE” having “TYPE_NAME” as attribute.

Validated and Activated the view. Perfomed Data Preview.

Expected Result was:

The actual result am getting after data preview is shown below:

Even if the above works, how do I calculate the average in a calculated column since the counter does not show in the calculated column.
