How to get rid of lsline in regression plot?

I have a regression plot with a blue lsline which I want to eliminate it but I don't know how.Thanks for any suggestion.

Answer 1

[Ced]

N = 15;
x = linspace(0,5,N)';
y = 1.3*x + 0.5*randn(N,1);

% 0. plot data and lsline
plot(x,y,'o')
lsline

% 1. find handle to lsline
h_lsline = findobj(get(gca,'Children'),'Tag','lsline');

% 2. switch off, i.e. remove lsline
set(h_lsline,'Visible','off');

Cheers
