Hello,

I am currently having some issues using xtgraph that I haven't experienced before. When I use the code I get an error message saying

"Problem giving meaningful names to all groups.
No solution."

I have tried the exact same code with a different exposure variable that is ordinal and has values 0-3, and it works fine. But when I switch exposure variabel to one with values 0-5 STATA gives me the above error message.

Does anyone know what the issue is here?


I am thankful for any type of help here,

kind regards
