Wrong data is shown on line chart when no date is selecte

[ishafate]

Hi i have the below line chart which shows the % female and Male 

the data is wrong when no date is selected , however when I select a date form the x axis i.e Feb 2021 in this example the data is correct and there is a huge difference. Can anyone help please?

My expression is : 

Count(distinct(id))/
Count(distinct TOTAL(id))

It is because your denominator is counting distinct IDs across all months. Try the following:

Count(distinct(id))/
Count(distinct TOTAL <Month> (id))
