Passing column name as argument to a function - is concatenating with : needed?

Neo

Below is a function where I am trying to pass a column name for plotting a distribution, but it is not working. I am wondering what is the correct syntax?

Names Default To Here (1);
getDistChart = Function({ColName}, {dC},

dC = Distribution( Continuous Distribution( Column( :ColName) ) );

return(dC);
);
//gt = getDistChart ("MyCol"); to test the function

I have already got the data table with MyCol as a column name open. I am wondering if I need to concatenate

:

 with the column name

ColName

If so how (as normal concatenation with || || does not seem to be working)?

Yes, it works perfectly for me with JMP Pro 16.1.0. I do not have any earlier versions of JMP installed to test. Your version is about 5 years old. JSL is constantly evolving, so it is possible that my syntax does not work for an earlier version.

 

You might contact JMP Technical Support (support@jmp.com) for help.

 

You might also try using expressions to accomplish what you want. They work for any version of JMP, since version 4. See if this version works:

 

Names Default To Here( 1 );

dt = Open( "$SAMPLE_DATA/Big Class.jmp" );

getDistChart = Function( {ColName, _LSL, _USL}, {distChart},
	Eval(
		Substitute(
			Expr(
				distChart = New Window( "" || ColName || " distribution", 
					Distribution(
						Stack( 1 ),
						Continuous Distribution(
							Column( As Column( ColName ) ),
							Horizontal Layout( 1 ),
							Vertical( 0 ),
							Capability Analysis( LSL( _LSL ), USL( _USL ) )
						),
						SendToReport(
							Dispatch(
								{ ccc },
								"Distrib Histogram",
								FrameBox,
								{DispatchSeg( LabelSeg( 1 ), {Font( "Segoe UI", 7, "Plain" )} ),
								DispatchSeg( LabelSeg( 2 ), {Font( "Segoe UI", 7, "Plain" )} )}
							)
						)
					)
				);
			),
			Expr( ccc ), colName
		)
	);
	Return( distChart );
);

getDistChart( "weight", 55, 185 );
