to smooth your measured x-displacements with a Savtizy-Golay filter you need data sampled at a fixed sample rate – which is exactly what you have. Fill a DoubleVector with your sampled data and apply your Savitzy-Golay filter. Have a look at this blog post to plot your results: https://www.centerspace.net/blog/nmath/net-math-with-microsoft-chart-controls-revisited/ .

Best,

Paul

The x dimension of my samples represents the position of a linear actuator when the sample was taken, but dynamic considerations require it to still be accelerating fairly substantially inside the area I am interested in measuring.
