comment Signal processing by means of WaveletTransform
@Ivan, there are good answers already; just let me add that from an engineering perspective you have to consider other aspects of your problem: the limitations of your device (inside the "real industrial object"?); is this an ongoing issue or a single instance...? And the socio-engineering aspects: who is going to maintain that code, what sort of environment? Do you need to implement it in hardware or software? You certainly can run Mathematica in a RaspberryPi, which is good news; but it all depends on the context of this problem.

@thils, I am not sure about your problem space. I added few ideas you can use. Good luck!

@thils, I noticed that the solution from NDSolve was differentiable already; hence my answer :)

comment Draw only part of axis in graph
Yes, not easy as a general problem - approachable for a particular case. It depends on how much effort you want to put in your graphic, I believe. OTOH, I haven't checked CustomTicks; if someone has a free solution that fits the bill, go for it :)

comment Draw only part of axis in graph
I believe removing axes altogether and adding your own as Epilog shouldn't be hard.

@thils, I believe you have to approximate y'[x] based on the data using finite difference coefficients. Have you considered this?

Thanks @rm-rf, I couldn't resist explaining this aspect of the Mathematica programming language :)

comment How can I get an approximate contour plot from a 3D plot?
Forgot to say that there is the caveat that the orientation wasn't uniform (some lines from left to right, others from right to left - kind of, you get the point) and I fixed that by hand based on my particular case.

See this mathematica.stackexchange.com/questions/20281/…. I have used it and works.
