SSRS Line chart

hi Microsoft Team,
I have created line graph chart in SSRS
In X-axis ,  displaying the date.
My requirement is to display only the business date that is retrieved as part of procedure.
I have set my interval as 1 and set min and max value as min and max business date that is retrieved.
but it is displaying all the dates, i should exlcude sat, sunday from this list and also the non -business dates which is not available in DB. please help.  why it is displaying all business dates without gap. 
if i remove interval , it is displaying date with 3 or 6 dates gap, but that is not what am expecting for.
i need to display all the dates in a month that is retrived using my dataset. hope there should be a solution for this issue. please help
