How to make a three variable line graph?

[Mark van Goor]

Dear all,

I would like to make a three-variable line graph like the attached one by Kruse et al (2022).

However, I am struggling to find the right command. I am aiming for a graph just like this one, but I want to plot continents rather than countries (MUS, GHA etc).

Can somebody help me to find the right command for it? I am still a beginner with Stata.

In Stata terms that graph is 7 y variables and 1 x variable. How do you have 3 variables? Please give a data example, spelling out how you want continents to be represented.

Essentially, the lines represent a third variable but they are categorical (string?) variables.

I am aiming to plot the manufacturing employment share for six regions for the span of 1990-2018. So, I'm trying to represent the six continents as six different lines in the graph.

Sorry, but that doesn't really answer any of the questions in #2. Code would differ according to whether values for the continents are held in 6 separate variables, or the continents themselves are 6 distinct values of a single grouping variable. There are suggestions of code in the paper cited in #2 and in #3.

If you need more help please give a data example as explained at 12.2 in https://www.statalist.org/forums/help#stata
