command for this graph

[Mere Wolfensberg]

Hi everyone,

I've just started out with stata and im trying to visualise the relationship between age and pay. Iw Ould like to make a graph like attached, but cannot find the command. Could someone help me?

Thank you!

HI Andrew, Thank you so much for your reply!
When trying to imitate your commands, Stata returns that my categorical age variable is omitted because of collinearity. Do you know why that could be the case?

Can you show your commands and if possible, post a data example that replicates this? If you include time effects in the model and have an age variable that coincides with time (e.g., in a panel of firms, all firms were founded at the start of the sample period), then the age indicators will be omitted as they are exactly collinear with the time effects. In your case, this does not look likely, but we will need more information to advise you.
