How to change the variables name in PCA loading scatter plot?

[#1]

Hello,

I'm trying to change the variables name in loading scatter plot but I can't. The variables included in PCA analysis are from two linked data tables. I'd like to change the columns name to new abbreviation names.

Thank you very much in advance.

The names of the variables in the loadings plot are the names of the data columns. Change the column names before the PCA.

If for whatever reason you don't want to rename the columns, you could make calculated columns when launching the platform.  Here is one table with a PCA showing the original names and one with shorter names:

Names Default To Here( 1 );

dt = Open( "$Sample_data/Quality Control/Chemical Reactor Process.jmp" );

New window("PCA Compare",
	h list box(
		dt << Principal Components(
			Y( :A.Feed.S1, :D.Feed.S2, :E.Feed.S3, :Total.Feed.S4 ),
			Estimation Method( "Row-wise" ),
			Standardize( "Standardized" ),
			Loading Plot( 2 )
		),

		dt << Principal Components(
			Transform Column( "S1", Formula( :A.Feed.S1 ) ),
			Transform Column( "S2", Formula( :D.Feed.S2 ) ),
			Transform Column( "S3", Formula( :E.Feed.S3 ) ),
			Transform Column( "S4", Formula( :Total.Feed.S4 ) ),
			Y( :S1, :S2, :S3, :S4 ),
			Estimation Method( "Row-wise" ),
			Standardize( "Standardized" ),
			Loading Plot( 2 )
		);
	)
);
