Hello I have a list of data that generates a very noisy graph.
I need this graph to be something like the purple line with the starting and the end values the same and the min and max values also the same.
Does anyone have a solution for this???

This smoothing function is too simple and depends on a manual slider (though something is needed to control the smoothing).
P.S. Plotting your data, I see a a pattern I had missed. Likely relevant to your smoothing effort 
@Joseph_Oster solution seems a good one, but data is a bit biased by the fact that values are all negative also on parts where there were positive.
You can do quite the same with a sliding window and analyse, min max and deduce the mean

Hi,
Comparing the graphs on the image I’d say the smooth result is not very accurate but maybe I’m missing something.
Simplifying and smoothing seems very precise but heavy.
The problem with smoothing polylines is that the ends in this case are not crucial and should not be anchored…
Puttering…
This is more of a data picker than smoother, though I thought at some point it can do both. 
P.S. Version ‘d’ (below) is the same as version ‘c’ but without the UI features.
have you consider the BLUR NUMBERS component? you may need a really high number of iteration in this case, but this is what you are trying to do in my opinion (it’s like during the covid, when the data of infected people had spikes every weekend but was averaged over some days to get a smooth graph)

I’ve never noticed Blur Numbers but it appears to work well, esp. when the ‘Iterations’ input is increased to 100K.
Another component on the same on the same ‘Maths | Util’ tab also looks interesting: Smooth Numbers
Smooth numbers is to set a delay so when the input change, the value changes over time and not instantly (right click on it)
