The workaround mentiones by Jonas helps for "single" plots, like
plot([1:10]); ylabel('test');

But, I am still facing this bug in subplots, which is pretty annoying.

I am using Octave 3.8.2 on Win 7.

Anything I can do to solve this?

I have experienced the same problem.
But the y-label is set correctly as soon as I enable the Oversampling option in the plot window. (Make permanent with Options->Update .../wgnuplot.ini) The Double Buffer Option seems to have an influence too.

I do not currently see what Gnuplot terminal is being used, since getenv('GNUTERM') does not yield anything.
Is this a Gnuplot bug?

Octave 3.8.1 from Untouched MXE Builds (April 28th 2014) with Gnuplot Version 4.6 patchlevel 4 on Windows.

The gnuplot in MXE build is "Version 4.6 patchlevel 1".

The gnuplot in Michael's 3.7.2+ MSVC snapshot (that isn't affected by this bug) is "Version 4.4 patchlevel 4".

In the newest mxe it is still 4.6.1.

Is it possible that there is a difference in gnuplot versions between the mingw and Linux machines?

Code does work correctly on a Linux machine with gnuplot 4.6.2.

ylabel isn't rotated parallel to y-axis - see attached plot.

I see this bug only on mingw (MXE) native & cross-compiled development versions.
(oldest mingw version here that shows this bug is 3.7.5 from mid-July)

This works OK on my Linux box, and with Michael's Octave-3.7.2 MSVC snapshot binary, and on 3.6.4.
(Probably also a regression)

To reproduce:

graphics_toolkit gnuplot
plot ([0:1])
title ("title") ## not needed
xlabel ("xlabel") ## not needed
ylabel ("ylabel")
