Re: st: Fw: Unable to combine graphs using -grc1leg-

[Nick Cox <njcoxstata@gmail.com>]

A wild guess is that something in your graph mentioning "key" is
triggering a bug deep, deep down in -graph-'s use of classes. That's
my guess for your first problem. You can check it by telling us
whether "key" appears in your graph in any sense: variable names,
variable labels, value labels, added text.

It could also explain what is going on in the second problem. Very
occasionally, if -graph- gets confused about classes whatever you try
afterwards is messed up. You have to back up and start again. In a
way, that's a tautology because it worked for you before you applied
-grc1leg-, yet didn't work after, but this has bitten me once and
that's my understanding. I blame the non-working classes.

There are no documented changes to -graph- in the latest update.
