[Octave-bug-tracker] [bug #51759] demo ("axis", 3) fails with gnuplot

[Dan Sebald]

Follow-up Comment #9, bug #51759 (project octave):

The construct I wrote is intended.  That's the "if labels is empty" part.  Bit
of a trick I suppose since it incorporates the conditional in the syntax.


labels(end+1:1) = {""};


is the same as


if (isempty(labels))
  labels = {""};


or


if (length (labels) == 0)
  labels = {""};


The bug is that labels can't be empty or the loop will fail.

The preference for patch 41540 or 41542 is up to you.  I know you like to get
rid of loops whenever possible, so I thought you might like 41542.
