in a block agenda view, I also want to incorporate the time grid to see the appointments of a day.
 
I tried with this code:
 
(agenda "" ((org-agenda-overriding-header "Calendar") (org-agenda-span (quote day)) (org-agenda-entry-types (quote (:timestamp))) (org-agenda-time-grid (quote ("t")))))
 
But there is no timegrid displayed, if no headlines match the agenda.
How can I always show the timegrid?
 
Kind regards
