plot() is very slow in Octave 3.0.1, but OK in Octave 2.1.73

Sun Aug 31 20:12:54 CDT 2008

Bug report for Octave 3.0.1 configured for i686-pc-cygwin

Description:
-----------

Simple plot() calls, e.g. "plot(1:3)", take approx. 10 seconds to complete. This slowness of plotting started when I installed Octave 3.0.1. I use Gnuplot 4.2.3, Cygwin version of 2008/7/25. 

Repeat-By:
---------

plot(1:3)

Fix:
---

I returned to Octave 2.1.73. There simple plot calls take less than a second. As I am writing this, I have just reinstalled Octave 3.0.1 only to call bug_report().
