In the figure, how to remove the item "aa" from the legennd without changing the shape of other items?
PointStyle = {'kp-', ...
'LineWidth', 1,...
'MarkerEdgeColor', 'k',...
'MarkerFaceColor', [0 0 .8],...
'MarkerSize',9};
plot(Points, PointStyle{:});
hold on
dataStyle = {'Marker','o', ...
'LineWidth', 1,...
'MarkerEdgeColor', [.8 0.4 0.2],...
'MarkerFaceColor', [1 .6 0.2],...
'MarkerSize',7};
plot(data, dataStyle{:});
if n <=3
%toDO
else
legend_str = {'aa','bb','cc'};
legend(legend_str, 'Fontsize',10,'Location', 'southoutside', 'Orientation','horizontal');
end
if n <=3
%toDO
else
legend_str = {'aa','bb','cc'};
legend(legend_str{2}, legend_str{3}, 'Fontsize',10,'Location', 'southoutside', 'Orientation','horizontal');
end
The shape of third item "cc" is changed:

Ok see this example , see if this is what you want:
plot(1:10,'-*r')
hold on
plot(2*(1:10),'-vg')
plot(3*(1:10),'-ob')
h=get(gca,'Children'); % grab all the axes handles at once
legendstr={'aa','bb','cc'};
legend(h([1 3]),legendstr{[1 3]}) % see the second label is skipped withoud changing shape
hold off

You could do it based on the order of appearance of the plots.
Assuming 'aa' is plot first, then 'bb' and then 'cc':
figure;
hold on
plot(rand(4,1),rand(4,1),'r','DisplayName','Red')
plot(rand(4,1),rand(4,1),'g','DisplayName','Green')
plot(rand(4,1),rand(4,1),'b','DisplayName','Blue')
hPlots = flip(findall(gcf,'Type','Line')); % flipped, because the lines our found in reverse order of appearance.
legend_str = {'aa','bb','cc'};
legend(hPlots(2:3), legend_str(2:3), 'Fontsize',10,'Location', 'southoutside', 'Orientation','horizontal');
