Single yaxis when using catplot

[Stephen Okiya]

Hi Stata users,

I am using a Stata user command

catplot

My example data is

* Example generated by -dataex-. To install: ssc install dataex
clear
input str6 gender str18 age
"Male"   "21 - 30 years"     
"Female" "51 - 60 years"     
"Male"   "61 - 70 years"     
"Male"   "21 - 30 years"     
"Female" "61 - 70 years"     
"Female" "31 - 40 years"     
"Male"   "61 - 70 years"     
"Male"   "21 - 30 years"     
"Female" "41 - 50 years"     
"Male"   "31 - 40 years"     
"Female" "41 - 50 years"     
"Female" "21 - 30 years"     
"Female" "51 - 60 years"     
"Female" "51 - 60 years"     
"Male"   "31 - 40 years"     
"Male"   "More than 70 years"
"Female" "61 - 70 years"     
"Male"   "More than 70 years"
"Female" "31 - 40 years"     
"Male"   "41 - 50 years"     
"Male"   "More than 70 years"
"Female" "51 - 60 years"     
"Male"   "51 - 60 years"     
"Male"   "More than 70 years"
end

and the code

catplot age, by(gender, title("What is your gender?")) blabel(bar, format(%3.1f)) l1title("") percent ytitle("Percent")

I have the following questions

1. Is it possible to have a single yaxis?
2. Can the frequencies by the sub-populations?

Thanks in advance!

Thanks for the data example.

catplot is from SSC as you are asked to explain (FAQ Advice #12). Here I give what you may be seeking, together with a plot I think better, using tabplot from the Stata Journal.

Bar colours should what your readers find culturally acceptable.

Touching bars may be preferred too.

end

set scheme s1color

catplot age, by(gender, col(1) title("What is your gender?")) blabel(bar, format(%3.1f)) l1title("") percent ytitle("Percent") name(G1)

replace age = subinstr(age, " years", "", .)
replace age = subinstr(age, "More than ", ">", .)
tabplot  gender age, percent(gender) title("What is your gender?") subtitle(%) showval separate(gender) bar1(color(orange)) bar2(color(blue)) name(G2)
