Hi there!

Normally, I understand one can print y-titles horizontally in Stata with the option,
Code:
 line yvar xvar, ytitle("Dependent Variable", orientation(horizontal))
I'd like to generalize this option to the use case of graphing lines over a third categorical variable,
Code:
 line yvar xvar, by(zvar) ytitle("Dependent Variable", orientation(horizontal))
Yet, when I attempt this, the y-title orientation remains vertical, despite having specified the "by()" option?

Any tips on how to print the y-title horizontally when using the "by()" option?
