I see.
Okay, two questions:
1) Do you actually have the font "Helvetica"? Unless you paid for it, I
doubt that, as it doesn't seem to be freely available.
2) Do you actually care about the font being "Helvetica"?
As the answer to question 2 is probably "no", here you go:
a) Set GDFONTPATH in your shell to a directory that contains the font
you want to use, in my case
export GDFONTPATH=/usr/share/fonts/truetype/msttcorefonts
b) Start Octave and give the font type explicitely:
figure;
plot(1:2,1:2);
xlabel('Label X', 'FontName', 'Arial');
ylabel('Label Y', 'FontName', 'Arial');
title('Title', 'FontName', 'Arial');
legend('Blue Line');
print('/tmp/testcase.png');
That worked for me, a more explicit explanation can be found at

This is more of an issue of the interaction between GD and gnuplot than
an Octave issue (apart from the fact that Octave sets the font to
Helvetica explicitely).
