Possible to show X axis intervals as discrete/visula units?

Hi

I have the chart displaying as show below - but it is hard to see where one day ends and another begins.

Is there a way of emphasising the boundary between the days? 

so something like this - ie stronger grid lines or something like that

Thank you

Jo

Sorry I seem to have answered my own question - it does not seem to be possible ... I looked up the post above.
