Italics in part of string variable / y-axis labels

[Amalie Timmermann]

Hi

I have made a graph in Stata and I created the y-axis labels using data from a number of variables:

by StudyID country (order), sort: generate y1 = _n == 1
tab y1

gen studylabel = Firstauthor if y1==1
replace studylabel = studylabel + ", " if y1==1 & (Gender !="" | Population_name != "")
replace studylabel = studylabel + Gender if Gender != ""
replace studylabel = studylabel + Population_name if Population_name != ""
replace studylabel = studylabel + " (n=" + n_string + ")" if n !=.
replace studylabel = studylabel + " (n not given)" if n ==.

sort order
g study = _n
labmask study, values (studylabel)

graph hbar AAbw, ///
over (MeanP501) bar(1, color(black)) bar(2, color(gs8)) ///
over(study, label(labsize(tiny))) ///
over(country, label(labsize(vsmall)) gap(400)) nofill ///
ytitle("Acrylamide (μg/kg bw/day)", size(vsmall)) ///
ysize(8) ///
xsize(5) ///
ylabel(0(0.1)0.9, labsize(vsmall)) ///
legend(size(vsmall)) ///
graphregion(color(white))


I have now been asked to show all "n" as "n", but I am not sure how I can convert part of the string-variable/label/axis-text to italics. I hope some of you might be able to help.

Best regards,
Amalie

{it:n}

For an example in code,

ssc type aaplot.ado

Perfect. Thank you so much, Nick!
