Place labels on boxplots with asyvars option

[Gabriel Jardanovski]

I generate a hbox with

clear
set obs `=9 * 2 * 5'
set seed 2803
gen y = rnormal()
egen x1 = seq(), to(4) block(1)

label define category 1 "First" 2 "Second" 3 "Third" 4 "Fourth"
label val x1 category

graph hbox y, nooutsides over(x1) legend(off) nofill note("")

I would like to set different colors for each category. I do this with asyvars option. But then the labels disappear. Would really appreciate some help on restoring the labels in the vertical axis when using asyvars option. Or, alternatively, suggestions on how to place different colors without using asyvars option. I'm using Stata 13 on Windows 10.

clear
set obs `=9 * 2 * 5'
set seed 2803
gen y = rnormal()
egen x1 = seq(), to(4) block(1)

label define category 1 "First" 2 "Second" 3 "Third" 4 "Fourth"
label val x1 category

graph hbox y, nooutsides asyvars over(x1) legend(off) nofill note("")
