Operating System: OriginPro 2022b (64-bit) SR1; 9.9.5.171 (Lehre)

Hej,

I have two measurement data sets with an A and a B column. My problem is that the second data set has more data points and accordingly more X-values in my A column. I see that the column contains the values of my first data set. I want to compare if my first data X-value is included in my second data set. Otherwise, I want to throw the second value away to achieve that both will have the same length.

Is there maybe a way to do it directly in Origin? I am a beginner.

Thanks!

Hi,

For you needs, I suggest you try the Interpolate Y from X tool (menu "Analysis: Mathematics: Interpolate/Extrapolate Y from X")

You can set Input to be your second dataset and X to be X of the 1st dataset. Then you can get the Y value of 2nd dataset on given 1st X values.
