octave> plot(rand(3))  % I see a colored plot with 3 lines
octave> print(2,'test.pdf','-debug')
---- begin /tmp/oct-AnIoEw.ps ----
%!PS-Adobe-3.0

----- end /tmp/oct-AnIoEw.ps -----
Ghostscript command: '/usr/bin/gs -dQUIET -dNOPAUSE -dBATCH -dSAFER
-sDEVICE=pdfwrite -dLanguageLevel=2 -dEmbedAllFonts=true -dOptimize=true
-dEPSCrop -sPAPERSIZE=letter -dFIXEDMEDIA -sOutputFile="test.pdf"
/tmp/oct-AnIoEw.ps /tmp/oct-wLu5fG.eps'
gnuplot-pipeline: '/usr/bin/gs -dQUIET -dNOPAUSE -dBATCH -dSAFER
-sDEVICE=pdfwrite -dLanguageLevel=2 -dEmbedAllFonts=true -dOptimize=true
-dEPSCrop -sPAPERSIZE=letter -dFIXEDMEDIA -sOutputFile="test.pdf"
/tmp/oct-AnIoEw.ps /tmp/oct-wLu5fG.eps ; rm /tmp/oct-wLu5fG.eps ; rm
/tmp/oct-AnIoEw.ps'

The generated test.pdf shows an x and y axis but the graph is a large black
filled rectangle.

Saving as png or jpg has the same result, but saving as svg does not have this
problem.

Some plots do not have this problem. The following plot does not have this
problem:

octave> clf()
octave> surf(peaks)

Saving that outputs the expected color graph.

My setup:
4.2.3-1-ARCH (Arch Linux)
GNU Octave, version 4.0.0
GPL Ghostscript 9.18 (2015-10-05)
