Hi. I can't plot the x axis data in findpeaks plot?

Thereby I cant find the locs of the peaks for which I cant find out the peakwidth. I need to find out the alternative peak distance e.g stick slip from the graph. I am attaching the data file and command file that I was using.

data=xlsread('r 1 1.xlsx');
x = data(:,1); 
dx = x(2) - x(1);
y = data(:,2); 
plot(x,y,'marker','d','MarkerSize',2);title('Pull-out Resistance vs Displacement','fontsize',20)
xlabel('Displacement, mm','fontsize',16)
ylabel('Force, N','fontsize',16)
pks=findpeaks(x,y)
%[pks,loca]=findpeaks(x,y)

Answer 1

[Adam]

pks=findpeaks(x,y)

is not a supported syntax (assuming the variables are named sensibly)

[___] = findpeaks(data,x)

is the syntax you would seem to want, as described in

doc findpeaks

I don't really understand your question though apart from that.
