Line break in an automatic twoway, by(x1 x2) subtitle?

[Klaus Steitzel]

Hi

I have the following situation:

To reproduce the problem:

clear
input x1 x2 x3 y
0 0 0 2
0 0 1 5
0 1 0 7
0 1 1 3
1 0 0 9
1 0 1 4
1 1 0 2
1 1 1 4
end

label define x 0 "very long word" 1 "much longer word"
label val x1 x2 x3 x

twoway bar y x1, by(x2 x3, row(1) note(""))

I am unhappy with the way Stata handles the value labels of the x2 and x3 variables. Is there any way to change this? I figured out that I can probably change the font size, but ideal would be a line break instead of the comma that Stata automatically added. Is there such an option?

Thanks so much for your consideration
KS

You can try inserting char(10) or char(13), but be careful as this might generate unwanted behavior elsewhere:

clear
input x1 x2 x3 y
0 0 0 2
0 0 1 5
0 1 0 7
0 1 1 3
1 0 0 9
1 0 1 4
1 1 0 2
1 1 1 4
end

label define x 0 "very `=char(13)' long `=char(13)' word" 1 "much `=char(13)' longer `=char(13)' word"
label val x1 x2 x3 x

twoway bar y x1, by(x2 x3, row(1) note(""))

If you try the three solutions below, you may find that at least the horizontal solutions accommodate your real value labels well.

clear
input x1 x2 x3 y
0 0 0 2
0 0 1 5
0 1 0 7
0 1 1 3
1 0 0 9
1 0 1 4
1 1 0 2
1 1 1 4
end

graph bar (asis) y, over(x1) over(x2) by(x3)

graph hbar (asis) y, over(x1) over(x2) by(x3)

graph dot (asis) y, over(x1) over(x2) by(x3)

Thank you both!
