Intersection issue with using ALL()

[Bastaba]

Hi all,

I have written this formula : 

CALCULATE(

CALCULATE(

[Fish]

,LASTDATE(Black_Table[Date_Modified]) 

)

,ALL('0_Date_Table_Extraction')

)

in order to get the last value of Fish by the column 'Date_Modified'

Then i want to display this 'constant' on a chart but only on the date of another table 'White_Table' with the column 'Common_date'
There is a relation 1 - N between 0_Date_Table_Extraction & White_Table on date columns & between 0_Date_Table_Extraction & Black_Table
I didnt find the way to display only on the intersection between 'Date_modified' and 'Common_date'
So i have this chart. I would like only 42% after the blue column (where there is 'common_date' data)

Can you help me please ?
