Custom Wave Scaling

Mon, 11/26/2018 - 01:09 pm

Hi All,

Is there a way to set a custom scaling for a wave? I have the following two waves I want to upload and plot.

Incident Energy (MeV)	Correction Factor
4.8	0.984757058
5.0	0.969265976
5.5	0.951633556
6.0	0.932863556

So in this case the x range is from 4.8 MeV to 6.0 MeV. The difference from one x value to the next is not uniform. The difference in incident energies is either 0.2 MeV or 0.5 MeV. If I use "change wave scaling" or "setscale" those functions scaling the index uniformly. Is there a way to set individual scales for each index?

I could superficially achieve this by plotting Correction Factor vs Incident Energy and display graph, but that's not actually scaling anything.

Thanks in advance, I hope this is clear.

Setting individual X values for each Y value is what XY pairs are for. So in this situation you must use an XY pair.
