Hi, I am applying findpeaks function to find the peaks of an oscilloscope signal but in the peak plot graph it is automatically changing the x-label with a large difference.

Can there be any command so that x-label will not change and it will remain same as my signal plot as it is creating a lot of confusion . please help me on an urgent note.

Hi Rikita, if you use findpeaks(y,x) where x is the x axis (linear or log scale) whose min and max match the oscilloscope trace and which has the same number of elements as y, i.e. either the x array output of the scope or linspace(xmin,xmax,numel(y)) or logspace(xmin,xmax,numel(y)), you should get the correct results for the peaks. Or is it some other problem, such as the text labeling?
