Making clustered column chart more pleasing.

Hello,

I am wondering is it possible to make the below chart more eye pleasing when it comes to spaces between columns? 

E.g. SYD-HKG column doesn't have any values for 9HHOP ir 9HZMK and LYLEO is way on the right. Ideally it would be that LYLEO would be in the middle of label "SYD-HKG". Any way to do it?
