Hello,

I wanted to use the graphical output of the findpeaks function of MATLAB, but I cannot manage to get the output in my graphe, as this line does not work.

findpeaks(app.UIAxes,data-y1,'MinPeakProminence',app.MinprominenceEditField.Value,'MinPeakWidth',app.MinmiddlewidthEditField.Value);

And if I remove the

app.UIAxes

part, I does open a new figure.

Thank you !

Hello , I had the same problem today! And I just found the answer! Try to don't use hold on to plot two data (I mean the original data and the peak points which you are looking for)! Plot them in the same line. For example Plot ( [data1],'g',[data2],'rs') Where each data can be the pks and locs data as the output of findpeaks function Data1 =original data which could be as x data or x y data. Data 2 =[locs,pks]
