Line graph showing % of feedback ratings

[AdrianLock]

We have very Large dataset as part of this there are a number of tables that pull in customer feedback from our own emailed feedback form.  I initally had a line chart displaying last 15 months by month on the X axis and the number of feedback on Y with legend breaking it down by satifiaction chosen "Very good", "Good", "poor" etc.  Then forcasting next 4 months.   That was easy and I get total number of feedback.  

I've been asked to change this as a % if I do pecent of grand total I Get from 0 - 10% which is not correct.    Table below is the fact table for feedback which also has a measure insdide which counts the number of feedback rows as well. 

This table is linked with 3 other tables 1 is a datetable linked to the date field.  Then there is a dim table for OrganisationSK  which has all org names.  With a dim table for satificationSK which store all satifiaction names.

CallRef	CustomerFeedback Date	Customer OrganisationSK	Customer SatisfactionSK
100123	1/5/2021	8	2
100124	1/5/2021	4	3
100125	4/6/2021	3	1

However despite my best efforts and colleagues I'm unable to get it to give me breakdown of the monthly feedback by satisfaction.  Nearest I got was with this below.  But that just worked out the % per satifiaction each month so 100% so each month totalled 8.3% not 100%. 

_CustomerFeedback% =

VAR _PositiveFeedback =
   CALCULATE([Count of feedbacks], ALLEXCEPT(FB_dim_CustomerSatisfaction,FB_dim_CustomerSatisfaction[CustomerSatisfactionName]))

VAR _TotalFeedback =
calculate([Count of feedbacks],ALL(FB_fact_CustomerFeedback))

RETURN
DIVIDE(_PositiveFeedback,_TotalFeedback,0)

Any ideas Please been all over the web but cannot get it right 🙂

Thanks for your response.  Ill anwser your questions.

1. I'm not sure what you mean by this?  I've only got a chart to display the values.   With data stored in fact\dimension tables as per standard star Scheme
   
   
2. [count of feedbacks] is count of  rows  in the table.

Hi  @AdrianLock ,

Can you truncate the relationship between the table and the chart so we can better help you.

What is the formula of [Count of feedbacks]？

Best Regards,

I've managed to fix it using this however this means I have to use CustomersatisifactionSK as the ledgend which is number rather than Name which is in the Dim table 😞

_CustomerFeedback% =

VAR _TotalFeedback =

   CALCULATE([Count of feedbacks], ALL(FB_fact_CustomerFeedback[CustomerSatisfactionSK]))

VAR _Feedbackbreakdown =

[Count of feedbacks]

RETURN

DIVIDE(_Feedbackbreakdown,_TotalFeedback,0)
