Ho to find peaks at step graphs?

Hi all,

how can i find peaks/first index of each step at the step graph?

I tried to use "find local maxima" function but i always get vector of zeros

the graphs represnts cumulative volume that deleiverd by step motor and I want to find the volume of each step

example of it is detailed below:

Thx,

Zach

Try to "detrend" the data first; then apply "findpeaks".
