[Octave-bug-tracker] [bug #35559] lines not printed

[Rik]

Follow-up Comment #4, bug #35559 (project octave):

I took your suggestion and compared the differences between plot() and line()
which did immediately reveal the problem.  The issue is that when using line()
the background color of the plot is set to [1 1 1] or all white.  When using
plot() the color is 'none' or transparent.

This doesn't seem to be a problem with the OpenGL renderer for the screen
because the Z-order stacking is correct, i.e., the stacking is background at
bottom, axis ticks on top of that, lines and any other objects at top of
stack.

When printing, however, the background of the plot is placed on top of most of
the other objects and hides the the tick marks and any line objects.

Sample code:


graphics_toolkit fltk
line ([-5 5], [1 1], 'marker', 'd', 'markerfacecolor', 'b')
get (gca, 'color')
ans =

   1   1   1

print foobad1.eps
set (gca, 'color', [1 0 1])
print foobad2.eps
set (gca, 'color', 'none')
print foogood.eps
