But it will decimate the data to points with the same X-step gap. Since my curve is exponentially rising, I need more/denser points at the end of my data. We have a script in excel which decimates the curve to points with for instance 0.1 step distance between the Y values! I tried to copy that in Origin. Switching X and Y and using the decimation function does not work, since my Y data is nor monotonic rising. Can you help me? Thank you! [/quote]   Check here to include your profile signature.
