Yeah, thank you for your bug report. This is a known issue, it's actually documented in the gnuplot interface code, but not in the user manual. Gnuplot does not support left or right triangle markers.

This could be added to the user manual as a known limitation.

If you would like to suggest a reliable way to produce these markers with gnuplot, we are very open to patches.

plot(1,1,'>') and plot(1,1,'<') result in up- and downward triangles ('^' and 'v') instead. Only seems to occur with graphics_toolkit('gnuplot').

OS: Ubuntu 18.04
gnuplot 5.2 patchlevel 2
octave 4.2.2
