I'm trying to create a line graph showing trends in religiosity across five waves of survey data (2, 3, 4, 5, and 7). As you can see I'm not using wave 6 of the survey, but when I put in the code below it creates a large conspicuous space on the x-axis in between 5 and 7 where 6 should be. I need the graph to have equal spaces across the 5 points on the x-axis.

graph twoway line religiosity wave, xlabel(2 3 4 5 7)

All help is appreciated! thanks in advance.
