I have Raman spectra which have different x axes
example:
X1
479.38822
481.36294
483.33687
485.31003
487.2824
489.25399
491.22481
493.19484
X2
478.83189
480.80782
482.78297
484.75734
486.73092
488.70372
490.67574
How can I put them into a same x axis without losing any important data points?
and the worksheet liiks like this:

Hi,
Either column is fine. If you choose “479” as Input column and “478” as X Values to Interpolate, “479” column is used as reference column and “478” column is interpolated into the same range of “479” column. Vice versa
Please refer to the detailed document on this page:

Another question, which one should I choose to interpolate? The one starting in 479? or the one in 478

Hi,
If you plot two spectra in one graph, I suggest Analysis: Data Manipulation: Horizontal Translate to move a curve to the same X range of the other. You can use Scale in tool to zoom in to a region.
Or, you can use Analysis: Mathematics: Interpolate/Extrapolate Y from X to interpolate one of the spectra.
Thanks,

Hi,
After you move the curve by Horizontal Translation, the source data in worksheet is updated automatically.

Hello,
Can the adjusted graph by Horizontal Translation's workbook be extracted?
