Can't create a pie chart using old count of column after using slicer

Hi,

I have a column named "A" which has unique values. And another column "Adate" which has corresponding dates. They are not unique. I am using slicer for representing date, which shows count of "A" column which falls under the start date and end date selected.

I want a pie chart which shows count of A depending on the slicer and also total count of A before applying the slicer.
Eg: If total count is 200. And depending on the slicer, if the count changes to 90. I want a chart which shows 200 and 90.

What will the approach be?

Any help will be appreciated!
Thanks in advance
