Thanks, it works. I suspected a regression since 
contourf(peaks,'EdgeColor','blue') works in Octave 3.0.x and 
surface(peaks,'EdgeColor','blue') works in Octave 3.1.54. Anyway, now I 
have the following (always reproducibile)

octave:1> surface(peaks,'EdgeColor','blue') # it works

BUT

octave:2> contourf(peaks,'EdgeColor','blue') # it does not work, as expected
error: set: unknown property "EdgeColor"
error: called from:
error:   /usr/local/share/octave/3.1.54/m/plot/__contour__.m at line 191, column 5
error:   /usr/local/share/octave/3.1.54/m/plot/contourf.m at line 71, column 5
octave:2> surface(peaks,'EdgeColor','blue') # it does not work anymore!!!
error: gnuplot (as of v4.2) only supports 2D filled patches
error: called from:
error:   /usr/local/share/octave/3.1.54/m/plot/__go_draw_axes__.m at line 543, column 4
error:   /usr/local/share/octave/3.1.54/m/plot/__go_draw_figure__.m at line 90, column 3

That is, if you call surface(peaks,'EdgeColor','blue') after a 
contourf(peaks,'EdgeColor','blue'), the former does not work anymore.

Best regards,
