Rebasing value to 0 when filtered on date slicer
Hello everyone, I am new to DAX measures in Power BI and couldn't find my way around rebasing values. I have a list of public firms and their share price changes for over a year (from 02 Jan 2019 till date). I have a date slicer for the same dates. The first row values i.e. the share price change % for the first day/2nd Jan 2019 is zero. What I am looking for is when I filter on the dates slicer - for example to see the moement between say 15 March and today, the value for 15 March should be zero (rebased to 0 on 15th March) It looks like above image now. I am attaching the desired look below (adjusted, slicer doesn't interact with table below) Please suggest.
