Problem with a graph twoway connected

[Guest]

Dear All,

I wanna have a graph showing the avarage yearly evolution of my variable mean_x. I want to highlight the crisis on the graph in 2008 2009 . I used the code:

graph twoway connected mean_x year, sort ///
xline (2008 2009, lstyle(dot) ///
ytitle("average x") xtitle("year") ///
xsca(titlegap(2)) ysca(titlegap(4)) ///

I'm confused because Stata neither produce anything nor shouts at me I have an error.

Please help me. I'm using Stata 17/SE. I used earlier Stata 15/IC and used such a code and it produced graphs. I'm really confused
