Pace per mile (Read 460 times)

When I import my runs to RA from my Garmin Forerunner 305 the pace graph shows up in 5 minute increments.  Is it possible to change the increments to show a horizontal line at every minute?  Or Every 2 minutes?  My run pace per mile is typically are in the 8:40 range.  I'd like to see how close I am at times from going under 8 or above 9.

When the increments are every 5 minutes it's difficult to tell.

Using Internet Explorer, not sure of the version, with Vista.

Thanks
