Can I get a line graph of requests created by date

Can I get a line graph of requests created by date

I tried creating a line graph of requests created by date, but the create date field seems to include the time, which makes every item on the X-axis appear as if the record count value is 1.  See below.  Is there a way to get this graph to show the requests created by date, regardless of the time? 

I'm guessing I could export the data to excel, maneuver excel, and get it, but it would be good to show this on a dashboard within Zoho Support.  We'd like to consistently understand our trends.
