Calculate the average based on week period

[Anonymous]

Hello, 

I am kind of new to power Bi, data visualizacion and report construction. I am trying to build a demand graph based on a weekly demand. 

The Graph shows the demand volume based on the different weeks. The week value is set through another table of periods which is associated with a date value from the demand table. As you may see, I have already an average line on the visualization with a very small, hard to see '4' number over there.

I want to show  the average per week on the data card that is set at the left. Any ideas on how I could be able to achieve this? I don't know how to calculate this average per week.

Hi @Anonymous ,

What you need is to create 2 measures :

1.Create a measure to get value of “Proposals demand”:

Proposal demand =

VAR week =
MAX ( 'Date'[Week of year] )
VAR p =
MAX ( 'Date'[Period] )
VAR k =
ADDCOLUMNS (
Demand,
"ind", CALCULATE (
MAX ( 'Date'[Period] ),
FILTER (
'Date',
'Date'[Week of year] = Demand[Week of year]
&& 'Date'[Index] = Demand[Index]
)
)
)
RETURN
CALCULATE (
SUM ( Demand[Proposals Demand per week] ),
FILTER ( k, Demand[Week of year] = MAX ( 'Date'[Week of year] ) && [ind] = p )
)

2. show the “average ” in a card:

Average of proposals demand per week= AVERAGE('Demand'[Proposals Demand per week])

3.Then you will see as below:
