This has been fixed on the stable branch.  It will be a part of the 4.2.2 bug fix release that is due out at the end of this year.

Confirmed.  The bug is still present on the development branch of Octave as well (11/6/17).  I'm adding Dan Sebald to the CC list as he has an understanding of the gnuplot interface.

Additional information: This bug is not present in Octave 4.0.2.
I have also verified that the same happens with gnuplot version 4.6 patchlevel 6. It seems that Octave is the cause.

Plotting line drawings with plot/quiver on top of image/imagesc fails. Minimal code to demonstrate:


graphics_toolkit('gnuplot')

A = [2 3 2; 4 5 6; 8 7 6];
imagesc(A)

hold on
plot([1 2],[3 4])


I am getting an error message:


multiplot> t='%float64' record=2 using ($1):($2) axes x1y1 title "" with lines linestyle 10 ;
                        ^
           line 0: unexpected or unrecognized token


My gnuplot is 5.0 patchlevel 3.
