Show error when item/ option is hidden

[naledi_h]

I am working with survey data. It's a lot more complex, but here is a sample structure to explain.

If I show a bar chart by gender, it would have 2 male and 8 female. I want to hide any response that has fewer than 5 respondents though. So I would show only the female bar and hide the male bar. I have a calculation to do this. 

Now I want to show the user a message, which explains that one of the options is not being shown because there are fewer than 5 respondents, so that they don't get confused and think there were no males at all or wonder where that bar has gone. I am struggling with calculating the number of respondents on the response level, when the response itself isn't shown. My expertise is in Tableau (where I would use an INCLUDE LoD) rather than PowerBI and I am struggling to translate my knowledge. 

The two approaches I was considering 
+ Compare the distint count of responses against the total in the data set and show the warning as soon as it is less than the total- I can get the total, but as the filtering works on the response level I don't know how to apply it in a measure to get the current distinct count of responses 
+ Calculate the individual response numbers for each response (e.g. 2 and 8 ) and then flag this as soon as the smallest value is below 5 - same issue, I don't know how to get the number of respondents per response and then get the smallest number from this 

Any hints into the right direction will be useful

I think I managed to get the temporary table solution to work. I will still need to do some testing but for now it looks good. Thanks so much.

Thank you for taking the time to respond and build out the solution Neeko. 

I should have mentioned that I need these results to be filtered dynamically with a set of slicers. I am not quite sure how to connect this new table to my existing table structure and also if the slicer would act at the right stage of the processing (from what I understand slicer actions don't affect calculations in tables as they are processed at an earlier stage?).

This is the data structure that I am working with. 

It feels like your approach of creating a table and then extracting a value from that is the correct one, but the table might need to be created more temporarily/dynamically/in a measure? I will do some research down that route but of course grateful for any further advice.

Hi @naledi_h ,

According to your description, here are my steps you can follow as a solution.

(1) My test data is the same as yours.

(2) We can create  a table.

Table2 = FILTER(SUMMARIZE('Table','Table'[Response],"Count_Type",COUNT('Table'[ID])),[Count_Type]>=5)

(3)We can create  a measure.

Warning = 
var _discount1=CALCULATE(DISTINCTCOUNT('Table'[Response]))
var _discount2=CALCULATE(DISTINCTCOUNT('Table2'[Response]))
return
IF(_discount2<_discount1,"Warning",_discount2)

(3) Then the result is as follows.
