[Octave-bug-tracker] [bug #31468] multi-line text objects

[Vanya Sergeev]

Follow-up Comment #10, bug #31468 (project octave):

I was interested in cell-based multi-line titles in Octave 3.4.2, and
discovered this bug report.

The __axis_label__.m patch below works but it produces extra newlines at the
end for me. For example:


txt = {'line1', 'line2', 'line3'};

txt(1:2:2*numel(txt)) = txt;
txt(2:2:2*numel(txt)) = "Z";
txt = [txt{:}];


yields:
txt = line1Zline2Zline3ZZZ

(The second line forgets to take into account that the cell length has been
doubled by the first, so as many extra newlines as there were original
elements are added at the end)

This does the trick for me:


if (iscellstr (txt))
  ## Treat cell string array as multi-line text
  txt(1:2:2*numel (txt)) = txt;
  txt(2:2:numel (txt)) = "n";
  txt = [txt{:}];
endif


Thanks,
