Help with Dax Formula - Average Hours Per Week Visual Assistance

[ianallen13]

Hello, 

I have a visual that shows the average hours worked on certain services per week.  On the whole, this visual / formula works exactly as I like it to - Except - what I would like is when all sessions are selected, it seems to just divide the total hours worked/by the total number of weeks, which for all-sessions - is not correct.  

Anyone have any ideas?

Here is the formula: 

Hours average per Week =

AVERAGEX(KEEPFILTERS(VALUES('Escalations_Cumulative'[Week])),CALCULATE(SUM(Escalations_Cumulative[Hours]))) 

Pic 1 is when it is filtered by session - works fine - which it should. 

Pic 2 is where I am trying to figure out how to get around it.  For the total number of weeks starting in the July 2020 session until now, after doing the math manually it is like 30+ hours on average per week.

Hello - yes - another person was able to help build a separate table within the file and that is how they were able to work around it.  Let me know if that helps?

Hi @ianallen13 

When you check box "Select all" it is like you are including values from blank rows in your model. it is better not to use select all and keep the boxes unchecked( it is doing the same thing as you check box all of them.

[ianallen13]

But I'd like it to show 'all weeks' from 'all sessions' as well to display the overall average from the time that we started this, but is there a way to write the formula to show that when they are all checked?

Embed your formula into a CALCULATE function and filter out the blank rows.

I'm still learning - how would that look?

Here is a quick example:

As you can see the 74 Blank rows are not included in the calculation of number of days.

do the same for your avarage formula where ever is neccessary.

I do not have any blank lines, as when each session is selected by itself - it works correctly - but when all sessions are selected (along with all weeks), I want it to show the average of all sessions.  

Sorry if I am not understanding correctly?

Power bi reports are treated case by case, so maybe a sample Pbix would be a better idea so i can work on it and help you understand.
