Count of date in a numeric range slicer

[Chandramouli_BI]

I have created a scatter plot like this below based on the PowerBI percentile lines(25th,50th,75th,100th) for both X & Y axis in Analytics pane Option in powerBI

I have a date column. I created a card visual & enabled count of distinct count of date. It shows value 30 (since I enabled april month in slicer). In the slicer settings I enabled between (What I want is it should give me a range from 1 to 30) . But it is showing date range,which I dont want. I want a range between 1 to 30 & based on this value & average of service average epk I can check each grid wise data.

Also after creating the range slicer for distinct count of date, Lets say the range is from 1 to 30, if selected from 1 to 20 then in the scatter plot the values below this should come. Someone please get me through this

I tried by separating the day from date column & then I kept day in slicer but when I select a range of 1 to 20 then in the y -axis vlaue is also showing 20 but the values count below 20 is showing wrong. Someone please get me through this
