How can i set a legend with plot and fill where i don't plot all curves?

clc;

clear all;

%Some example Data

x1=linspace(0,10,1000);

y1=sin(x1);

y2=0.05*x1.^2;

y3=x1/7;

hold on;

grid on;

p1 = plot(x1,y1);

p2 = plot(x1,y2);

p3 = plot(x1,y3);

filler = fill([x1;x1], [y1;y2], 'b', 'edgecolor', 'b', 'edgealpha', 0.1);

%This is what does not work: It does not plot the filled Area with the lines of the plot

legend([p1 p3 filler], {'Linie 1','Linie 3', 'filled Area'});

% This is what i found if i got the 'patch' in the legend and let the FaceAlpha as in the Area

% PatchInLegend = findobj(icons, 'type', 'patch');

% if ~isempty(PatchInLegend)

% set(PatchInLegend(1), 'FaceAlpha', 0.4);

% end

Get rid of the first argument to legend():

% Add legend
legend({'Line 1', 'Line2', 'Line 3', 'filled Area'}, 'Location', 'north');

But i can't do that if i just want to have Line 1 and Line 3 in the Legend. That is what i acctualy wanted to know. Sorry for the confusion. I changed the code so it's little bit more clear.

Set the handleVisibility to 'off' and leave line2 out of the legend argument list:

%Some example Data
x1=linspace(0,10,1000);
y1=sin(x1);
y2=0.05*x1.^2;
y3=x1/7;
hold on;
grid on;

p1 = plot(x1,y1, 'r-', 'LineWidth', 2);
p2 = plot(x1,y2, 'g-', 'LineWidth', 3);
p3 = plot(x1,y3, 'b-', 'LineWidth', 2);
filler = fill([x1;x1], [y1;y2], 'b', 'edgecolor', 'b', 'edgealpha', 0.1);
p2.HandleVisibility = 'off';
% Add legend
hLegend = legend({'Line 1', 'Line 3', 'filled Area'}, 'Location', 'north')
