Filtering a Dashboard with the same filter for two views

Hi All,

I am using two views ( Chart and Timediff)  in a dashboard. In both the views I have the same Filter (Date Filter - which is in itself a table calc). (Please find attached the sample workbook)

I would like to use the Date filter to change both my views in the Dashboard. However, I am unable to find a option to do so.  I only have the option to bring in both the filters from both the views and use them to filter the views separately. 

Can someone please suggest as to how can I use the same filter (Date Filter) to filter both the views at the same time. 

Thanking you all

Regards,

Rishi
