| Okay, two questions:
| 1) Do you actually have the font "Helvetica"? Unless you paid for it, I

| 
| 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');

You may also specify a default font for all labels by setting a
default property in the root figure:

  set (0, 'defaulttextfontname', 'Arial');

Then you do not need to specify individually in each text object.
