[Pantxo Diribarne]

Follow-up Comment #2:

Yes, as you discovered, the only tool chain that supports transparency for
vector outputs is based on conversion of svg. Using it to produce the raw pdf
as you propose in comment #1 could be envisaged. Another alternative, if you
can live with path rather than text, is to wait for the upcoming Octave 7
which will support the latex interpreter (using an external latex engine):


set (0, "defaultaxesticklabelinterpreter", "latex", "defaulttextinterpreter",
"latex")
x=linspace(-1,1,101);
s = 0.15;
y1 = exp(-(x/s).^2/2);
y2 = 0.75*exp(-((x-0.3)/0.15).^2/2);
hold on
h = fill([x 1 -1],[y1 0 0],'b', ...
  'FaceAlpha',.3);
set(h,'EdgeAlpha',.3); # this line causes bug
fill([x 1 -1],[y2 0 0],'r', ...
  'FaceAlpha',.3);
hold off
box on
title('print -dpdfcrop -svgconvert')
print -dpdfcrop -svgconvert curves
