I've checked 52c205a0ad88 and the issue seems fixed.
Also updated http://josoansi.de/octave_plot_compare/compare_plot_demos_01.html

Closing as fixed

Since it seems like an easy fix, I lowered the gnuplot version to 4.6 in _gnuplot_has_feature_ (http://hg.savannah.gnu.org/hgweb/octave/rev/f7ff29ff2763).

I've added Dan Sebald to the CC list.  Certainly this used to work back in 4.0.3 so this is a regression.

In __gnuplot_has_feature__.m, line 52,
gnuplot's property "needs_color_with_postscript" is set to 5.0.
If I change it to 4.6, and use the command

print -dpsc out.ps

I get a color image (print out.ps still produced a gray postscript file, why?)

I think that the property "needs_color_with_postscript"  should be set to even lower gnuplot version, but I do not have 4.4 or 4.2 installed now to check

Confirmed.  4.6 fails, 5.0.3 works.

See also bug #48033 for a much broader issue of recent changes not working with gnuplot 4 on the current default branch.

hg id 2e49ab3d6b48 somewhere lost the ability to print colored plots with gnuplot 4.6


graphics_toolkit gnuplot
plot (1:10, ";;", 1:3:10)
print out.png


produces the attached png. The plot onscreen looks fine. Mike told me on IRC, that the print is colored as usual with gnuplot 5.0.3
