I just checked and it's working fine. I would suggest updating the packages:

ssc install joyplot, replace
ssc install palettes, replace
ssc install colrspace, replace

and try again.

Still reporting an error.

Which Stata version? and when you type which joyplot does it say v1.61?

[Stata-ww]

stata15

which joyplot.ado E:\stata\stata15/ado\myplus\j\joyplot.ado *! Joyplot v1.61 (01 Mar 2023) *! Asjad Naqvi ([email protected])

I've found the reason: levelsof in joyplot.ado is the latest version, but I'm an older version and won't return the staging: r(r). I added "qui tab `over'" in joyplot.ado and it was up and running. Thank you for your reply. My English is not very good, there are some small mistakes in the reply, please forgive me. thank you。3Q。

Thank you so much for finding this! I didn't realize that levelsof didn't return r(r) in older versions. This is a major issue for backward compatibility in most of the packages that I will fix over time.
