I created the attached data file from data on the web. I typed::

hbar pctdiff,l(name)

using Nick Cox's hbar do file. I got a graph and wanted to edit it but got the message repeatedly that: the graph is not a live graph and cannot be edited. I have been able to do this before but don't understand why I can't do it again; Any help would be appreciated. I have tried to do this recreating the graph and using an old one using both Stata 15 and 16.

Any help would be appreciated.
