Line chart Y-Axis is duplicating values

[AmiraBedh]

I have this following measure :

Marge =
CALCULATE(DIVIDE (
SUM( FCTVentes[prix_vente] ),
SUM( FCTVentes[prix_achat]),0),
USERELATIONSHIP(dim_calendrier[id],FCTVentes[fk_date_vente]))

The result is a percentage formatted like below :

When I try to create to LineChart with a year filter like below :

I see that the Y-axis is duplicating values when the 2020 year is selected.

When selecting the year 2021 also, it is the same :

Also, I want that the Y-axis starts from 0 (the display), even if there is no data with 0%.

Whats happening there is since the range is small and the values are low it is showing the round off values. If we simply increase the decimals for the axis values it will be fixed.
