legend on every second data set

[oxyopes]

Hi friends,
how ca i put a legend on every second curve in a graph?

octave> plot(x1, y1, '*', x1, fit_y1, '-')
octave> hold on
octave> plot(x2, y2, '*', x2, fit_y2, '-')

Now a legend only for (x1, y1) and (x2, y2), and not the fitting curves.
Any tip?
Thanks in advance ...

What works under Matlab (and probably also under octave) is to
re-order the children to have the children for which you want a
legend first in the children list, then use "legend" command.
This means:

h = get(gca, 'children')
% re-order handles in h
set(gca, 'children', h)
legend('item 1', 'item 2')

This does not work for me. Look

octave-3.0.0:13> plot(g1(:,1),g1(:,2), '*;legend 1')
error: plot: properties must appear followed by a value
error: evaluating if command near line 58, column 6
error: evaluating if command near line 57, column 4
error: evaluating if command near line 55, column 2

Any idea?

plot(g1(:,1),g1(:,2), '*;legend 1;')

Note missing ; character in the original command

you forgot the second semicolon:
plot(g1(:,1),g1(:,2), '*;legend 1')
should be:
plot(g1(:,1),g1(:,2), '*;legend 1;')
