How to display measure value even it's blank

[GeekAlfPro]

I have a measure that calculate the first day of the month of my dataset for my vehicles

Date début données = CALCULATE(
        IF(
            ISBLANK(FIRSTDATE(daily_aggregate_final[Date])),
                    BLANK(),
                    FORMAT(FIRSTDATE(daily_aggregate_final[Date]), "d")
            
        )        
        )

the trouble is if there no data at all for a specific vehicle, it is not displayed.

it works with the following code

Date début données Capte = CALCULATE(
        IF(
            ISBLANK(FIRSTDATE(daily_aggregate_final[Date])),
                    0,
                    FORMAT(FIRSTDATE(daily_aggregate_final[Date]), "d")
            
        )        
        )

But i want to have blank instead of 0

how can i modify my measure to display all vehicles even if there no data.

Thanks

If it's only for a visual, you could right click on your vehicles in the visualization builder and select Show items with no data.
