How to change the colour or text or delete some text of the default graph in findpeaks function?
In this code below from matlab link https://ch.mathworks.com/help/signal/ref/findpeaks.html
It used "findpeaks"
% generate data
x = linspace(0,1,1000);
base = 4*cos(2*pi*x);
Pos = [1 2 3 5 7 8]/10;
Hgt = [3 7 5 5 4 5];
Wdt = [1 3 3 4 2 3]/100;
for n = 1:length(Pos)
Gauss(n,:) = Hgt(n)*exp(-((x - Pos(n))/Wdt(n)).^2);
end
PeakSig = sum(Gauss)+base;
% findpeaks function
findpeaks(PeakSig,x,'MinPeakProminence',4,'Annotate','extents')

findpeaks(PeakSig,x,'MinPeakProminence',4,'Annotate','extents');
legend({'xyz','abc'},'FontSize',12,'TextColor','green');

Thanks for your reply.
I would like to change the colour of the line, and not the colour of the text color as shown below in circle.
