Details:

Steps to reproduce:



%%%%% In file myboxplot.m
function myboxplot(LPercentile, Median, RPercentile, Height, LineWidth,
BoxHeight, MarkerColour, MarkerSize)
% A simple custom boxplot function
  hold on
  plot([LPercentile, RPercentile], [Height, Height], 'linewidth', LineWidth,
'color', 'k', 'linestyle', '-');
  plot([LPercentile, LPercentile], [Height - BoxHeight/2, Height +
BoxHeight/2], 'linewidth', LineWidth,  'color', 'k', 'linestyle', '-');
  plot([RPercentile, RPercentile], [Height - BoxHeight/2, Height +
BoxHeight/2], 'linewidth', LineWidth,  'color', 'k', 'linestyle', '-');  
  plot(Median, Height, 'marker', 'o', 'markersize', MarkerSize,
'markeredgecolor', 'k', 'markerfacecolor', MarkerColour);    
  hold off
end



In a terminal:



>> myboxplot(1,2,3,1,3,1,'g',20); hold on
>> myboxplot(2,3,5,3,3,1,'r',20); hold off
>> axis([0,6,0,4]);
>> saveas(gcf, 'out.pdf', 'pdf');



Bug: The plot within the octave session looks fine, but the file out.pdf is
missing the 'whiskers' and only shows the coloured markers.

Notes:

* Reported here
<http://stackoverflow.com/questions/39746234/octave-failing-to-include-parts-of-a-plot-when-saved-to-file>
first; Andy could not reproduce issue on his linux(?) installation. 
* This happens regardless of output format chosen. 
* Tested on linux mint 17.3 (based on ubuntu trusty) on a 64bit PC, and on
linux mint 18 (based on ubuntu xenial) on a 64bit laptop.
* Tested on both 4.0.3 stable, and 4.2.0-rc2 (both compiled using qt4 rather
than qt5).
* Saved pdf is as expected in matlab within the same linux environment on the
PC.
* Saved pdf is as expected in octave 4.0.2 on a windows environment on the
PC.
