Issue in chart for Zero measure values

Hi,

I have created a chart based on Last week end date and two measures "Open"(Count of Open) and "Close"(Count of close).

For some weeks I do not have values for "Open" and "Close" so Chart is not displaying that week but business is asking to display all weeks. How can I achieve this ?

see the below picture:

In the above example, I do not have "Open" and "Close" values for 31-Jan, 20-mar, 27-Mar,  3-Apr, 10-Apr, 17-Apr So these week end dates are not displaying in Chart but according to business I need to display these dates with "zero" values. How can I achieve this ?

Please help me, Thanks in Advance !
