Dashboard to display actual decimal value or rounded to lower number

Hi all!

We have a DB view that contains predicted vacation balance for each person, with effective Date and Vacation balance value. 

When creating dashboard each person can view his/her data, we see that dashboard rounds up decimal values of vacation balance to closest integer. Can this behaviour be changed? Either to show actual value ( for example 2.79) or always rounded to lower (2).  

Atatched you can find sample data used to build dashboard above.

Thanks!
