[Pkg-octave-devel] Bug#660750: octave-epstk: invisible axis ruins plot line

[Francesco Potortì]

Package: octave-epstk
Version: 2.3-2
Severity: normal

Apparently, making an axis invisible when a plot line is over it,
deletes the plot line in the place where they overlap.  I append an
Octave test file wich, in the [0 0.5] interval, produces a horizontal
line overlapping an invisible axis, which is thinner than the rest of
the plot line.
