Fixed in this changeset http://hg.savannah.gnu.org/hgweb/octave/rev/9552138fe6f5. This is on the development branch of Octave stored with Mercurial. The original reporter will need to build Octave from source code or wait until the 4.2 release to see the fix.

This bug is still present on the development branch (12/28/14). I find that even simpler code can illustrate the problem.

This should be a blue line but is red.

It appears to work correctly with older versions of gnuplot.

Versions:
octave 3.6.2
gnuplot 4.4.0

tested: using the OpenGL+FLTK graphics in my Debian works correctly, but not with gnuplot.

versions:
octave 3.6.2
gnuplot 4.6.0
fltk 1.3.0

Your plot3 example seems to work correctly for me with the current development sources using the OpenGL+FLTK graphics, but not with gnuplot, which consistently displays a red line with blue circles.

Apparently this problem only happens on some systems. I can confirm this bug in archlinux on both 3.6.2 and ea6997657614. However, several people on IRC did not experience the bug.

plot3 gives incorrect line colors, plotting
I get a blue circle but a red line.

Plotting two lines the second color will be blue, and the third one will be magenta, and the fourth orange (i think), then red comes again.

Apperently the issue is still present in 3.7.0, using both gnuplot and fltk (it was testted by irc users, not me directly).
