Hello,

I wonder if I could please get advice on how to display the number of observations underneath twoway line plots, much like the option
Code:
 sts graph, by() risktable
For instance the sts graph manual (https://www.stata.com/manuals13/ststsgraph.pdf) shows the "number at risk" in this graph Array

I would like to produce the same thing for a twoway plot for instance for this code

Code:
use http://www.stata-press.com/data/r16/nlswork.dta, clear

gen ct_wks_work = 1 if wks_work !=.
gen ct_wks_ue = 1 if wks_ue !=.

collapse (mean) wks_work wks_ue (count) ct_wks_work ct_wks_ue,  by (year)

twoway (line wks_work year )   ///
       (line wks_ue  year)

I produce the following twoway graph but I would like to include two rows for the values of ct_wks_work ct_wks_ue
Array
