Show all scale division marks at graph

Hi, everyone!

I am trying to show average count of ‘orders’ through ‘hours’ axis, which has all 24 hours at one graph. However, some of the ‘hours’ is not exist, so, graph does not show all 24 hours on X-axe. I tried make ‘Continuous’ type of X-axe, but result is (screenshot 1). I am trying to catch (screenshot 2) with one addition, that I want see all 24 hours on scale division. Any solutions? Also, I am attaching screenshot 3 with dataset, may be that will help . 

Thank you,

Regards.
