Should "set ..." trigger a replot event?

[Philipp K. J. <ja...@ie...>]

Question/Suggestion for the group mind: 

Should changing an option with "set ..." automatically
replot the graph?

Traditionally, changing an option with "set ..." does 
not have any immediate visible consequences - not until
the next plot, splot, or replot (or refresh) event do
the changes become visible.

This is a major point of confusion for new users, and
frequently an annoyance even for experienced users.

Hence, would it make sense to re-draw the graph 
automatically after "set"? Or (better!) have an
internal variable/option (eg "set autorefresh") 
that controls this behavior?

Obviously, for batch processing, autorefresh does
not make sense. Also, a previous plot must exist.

So, here is the list of conditions that I could foresee:

1) IF the terminal is an interactive terminal
2) and if a previous plot exist in the history
3) and if autorefresh is not False
THEN automatically run refresh after each set.

Thoughts?

Best,

		Ph.

I could see an "autorefresh" mode would be nice to have in some cases,
but if it was the default, I´m sure it´d annoy me on a daily basis.

Btw., you can always end your "set .." command with ";rep" ;-)

(What the heck is the ambiguous "re" supposed to do? It´s neither
"replot" or "refresh", nor "reset". Is it "reread"?)

That's why I think it's important to be able to
turn it on or off.

Obviously. But whenever I "always" have to tell a 
computer to do a thing - shouldn't I be able to tell 
it ONCE? ;-)
