[Gnuplot-info] Two formats for axis ranging -- any difference?

[Craig D. <def...@bo...>]

Is there a functional difference between these two cases?

   set xrange [0:10]
   plot '-' using 1 notitle with lines

and 

   plot [0:10] '-' using 1 notitle with lines

More generally, is there ever a reason one would want to use one vs. the other?  Currently the Perl module PDL::Graphics::Gnuplot supports syntax to generate either of those case, but it would simplify the syntax and the API if we didn't have to keep both of those cases.

Yes.  Just "show xrange" after each of those to see for yourself.

To answer such questions, you can always "save" the state of gnuplot to 
a file after such a command in a fresh, interactive session, and compare 
the resulting files.

That doesn't actually answer my question.  Sure, the two styles of calling produce different internal state -- but do they ever produce different plot output?

It answered the question you asked.  Not my fault if that wasn't the 
question actually wanted to ask.

That depends entirely on what your _next_ plot command looks like.

Oh, please.  Okay, I'll try again:

Sure, the two styles of calling produce different internal state -- but do they ever produce different plot output for the current plot (disregarding any additional commands sent later)?
