I have posted a small Python function with a usage example for a chart with a Vertical or Horizontal Reference Line at the mean on my Onedrive site here

Usage is explained in the comments.  You run the first block of code once in a session.  Then the usage is via a small BEGIN PROGRAM python3 blockthat provides the specific GGRAPH/GPL code and the name of the variable whose mean is needed.  You include a GUIDE form.line statementlike this in the GPLGUIDE: form.line(position({mean}, *))
and call the function like thisggraph("V1", cmd)
specifying the reference variable name in quotes and the GPL command.
Let me know of any issues.
