current 30 days vs previous 30 days line chart tooltip

[Daniel29195]

Hello,
is there a way to show which is the previous date that the line chart is comparing to ? 

so if i put my mouse on the date :  12/2/2019 , the tooltip should me :  vs which date the current date is compared ? in this example : 11/2/2019 

thanks in advance,

Hello @menglaro78 ,
yes, it crossed my mind, 

but i thought there is an easier way, (without writing DAX ),

cause the tooltip below , needed a "big" DAX expression.

You can create a "Tooltip" type page.
Create the page by inserting the date, date -30 and values.
This way you get the required result.
