Total Average not working

[peterderrington]

I'm trying to show a changing average line on my chart but i can't seem to work out how to write the expressions.

The red line shows the overall average over the whole time (it uses this expression - avg(TOTAL AGGR(Sum({<Sheet_name={'Wansbeck'},day={'Monday'}>}WGH1),Date)) Despite the dimension being WeekYear 😞

I have 3 conditions (PreCovid, Covid & HomeSafe Weekend) that i want to display the averages for.

They run like this:

Week23 2019 - Week 11 2020 = PreCovid

Week 12 2020 - Week 18 2020 = Covid 

Week 19 2020 - Week 31 2020 = HomeSafe Weekend

When i try the expression = avg(Total Aggr(Avg({<Sheet_name={'Wansbeck'},day={'Monday'},[Named Change]={'PreCovid'}>}WGH1),MonthYear)) I just get this:

Which just overwrites the overall average.

If i try: avg(Aggr(Avg({<Sheet_name={'Wansbeck'},day={'Monday'},[Named Change]={'PreCovid'}>}WGH1),MonthYear)) Then as you can the average line ends but it ends early (Week 9 instead of Week 11) but also its not a true average as that should be solid at 2.51

What am i doing wrong and ideally how could i show one line changing between the three states?

Here is a shot of the data in a straight table:

@peterderrington  Is it because you are using  MonthYear instead of WeekYear in aggr?

avg(total sum({<Sheet_name={'Wansbeck'},day={'Monday'},[Named Change]={'PreCovid'}>}WGH1),WeekYear)) 

[peterderrington]

No, i tried your expression and it just said that the expression was wrong apparently after WGH1) its garbage

I did however adapt the original one to WeekYear not Month Year -  avg(Aggr(Avg({<Sheet_name={'Wansbeck'},day={'Monday'},[Named Change]={'PreCovid'}>}WGH1),WeekYear))

and now it continues to the end of the section which is great but it doesn't show a straight line (if i add Total then it just goes to the very end which is still wrong)

We're getting close....

@peterderrington  missed aggr..typo

avg(total  aggr(sum({<Sheet_name={'Wansbeck'},day={'Monday'},[Named Change]={'PreCovid'}>}WGH1),WeekYear)) 

[peterderrington]

Nope, that doesnt work - it looks like this now:

@peterderrington  is the straight line generated showing correct values?

[Chanty4u]

can you try this?

avg(total  aggr(sum({<Sheet_name={'Wansbeck'},day={'Monday'},[Named Change]={'PreCovid'}>}WGH1/sum({<Sheet_name={'Wansbeck'},day={'Monday'},[Named Change]={'PreCovid'}>}WGH1),WeekYear))

[peterderrington]

No that shows as an error in expression with the first ( highlighted in Red

[peterderrington]

Yes it showing an overall average of 2.35 which is correct for the entire time line

[Chanty4u]

only close is missing .. can you try this

avg(total  aggr(sum({<Sheet_name={'Wansbeck'},day={'Monday'},[Named Change]={'PreCovid'}>}WGH1/sum({<Sheet_name={'Wansbeck'},day={'Monday'},[Named Change]={'PreCovid'}>}WGH1),WeekYear)))
