#1 Value labels are not shown by default. You must specify (e.g.) -xla(, valuelabel)-, as is documented in the help for axis_label_options. #2 Consider . sysuse auto . scatter mpg weight . sort mpg . scatter mpg weight The -sort- affects the sort order of the data, but is irrelevant to the scatter plot, which is unchanged. What you asked for "did work"; the problem is in your expectations. You can't do a scatter plot versus weight using the sort order of mpg because it would no longer be a scatter plot versus weight. (You can connect points in that order, but that is a different story.) In a simpler analogue of your data users_meeting_venue order_in_2007 Essen 1 Boston 2 Stockholm 3 London 4 Roma 5 Los Angeles 6 If you -encode users_meeting_venue- you get encoded users_meeting_venue order_in_2007 value 1 label Boston 2 value 2 label Essen 1 value 3 label London 4 value 4 label Los Angeles 6 value 5 label Roma 5 value 6 label Stockholm 3 But really what you want to do is to attach the names as labels to -order_in_2007-! One solution to your problem to the -egen- function -axis()- in -egenmore- from SSC. You create a new variable like this: egen x_axis = axis(_se study), label(study) and then use -x_axis- as your x axis variable, not -study-. It may well be that egen x_axis = axis(_se), label(study) is enough, but what I wrote first includes protection against ties on standard error.
