Label X-axis in fit y by x platform with different column

Hello,

Is there any easy way to change the x-axis label with a different column in the fit y by x platform?

Thanks!

Here is a simple example that draws the graph and then resets the X label to the name of the 2nd column in the data table.

names default to here(1);
dt=open("$SAMPLE_DATA/big class.jmp");
Graph Builder(
	Size( 528, 456 ),
	Show Control Panel( 0 ),
	Variables( X( :weight ), Y( :height ) ),
	Elements( Points( X, Y, Legend( 6 ) ), Smoother( X, Y, Legend( 7 ) ) )
);

current report()[texteditbox(3)]<<set text(column(dt,2)<<get name);

Thanks! I should have made my post more clear.

I am trying to change the entire x-axis label and x values in the fit y by x platform with a different column. Since fitting a regression line requires both numeric/continuous variables, I cannot use Run ID as the x variable as it contains characters, so I was wondering if it is possible to replace the x-axis label/values with a character column after the regression is fit.

Example of data: Run (numeric run number), Run ID (character), regression fit output is what I have using the two numeric columns, but I would like the x-axis to be like the x-axis from the graph builder using Run ID (character).

Thanks for the help!

I think you want to use Value Labels. You probably don't want to code them each individually, so....

This is ugly, and I don't like using "Eval( Parse(....) )", but it works.

Names Default to Here( 1 );
labs = {};
For Each Row( Insert Into( labs, Char( :Run ) || " = \!"" || :Run ID || "\!"" ) );
Eval( Parse( ":Run << Add Column Properties(
	Value Labels( {" || Concat Items( labs, ", " ) || "} ),
	Use Value Labels( 1 )
)") )
