Hi All

I have a data set of over 4500 data points. I want to reduce this to roughly 200 points for use in a plot.
The data is an output from a tensile tester, and I am looking to pair it and plot against a data set from a numerical simulation, which is only outputs 200 data points.

What is the best way to do this, without losing the trend I have in my mechanical testing data set?

Thank you all for your time

Regards,
Tom
