Add reference line to distribution plot

[#1]

Hi,

I want to add a reference line in the distribution plots. 

The reference values are stored in the second file "Reference data table"

Here's my code:  It doesn't works on histogram plots but works on Var charts. Any advice would be appreciated

Names Default To Here( 1 );


dt1 = Data table( "Reference data table.jmp");
dt2 = Current Data Table();
Col_List = dt2 << Get Column Group( "Tests" );
								


vc2 = Eval(
	Eval Expr(
		dt2 << distribution(
			Stack( 1 ), 
			
			Column( Expr( Col_List ) ),
			Horizontal Layout( 1 ),
			Normal Quantile Plot( 1 ),
			Vertical( 1 ),
			Process Capability( 0 )
			
		)
	)
);

aa_refs = Associative Array( dt1:Tests << get values, dt1:Mean << get values );

For( i = 1, i <= N Items( Col_List ), i++,
	If( Contains( aa_refs, Col_List[i] ),
		Report( vc2[i] )[Framebox( 1 )] << DispatchSeg( CustomStreamSeg( 3 ), {Line Width( 2 )} );
		Report( vc2[i] )[AxisBox( 1 )] << {Add Ref Line( aa_refs[Col_List[i]], "Solid", "Green", "RTS", 2 )};
	)
);

@txnelson any suggestions?

Here is a rework of your script.  The issue you are having is that the Display Tree for Bivariate is different than the Display Tree output from the Variance charts.  You need to read the section in the Scripting Guide on Display Trees so you can work with the various forms of the output.  Also, the Means from your reference table seem to be wrong.  See the output below.  The mean for Current 1.1 is listed as 166, and the listed maximum is only 2.49.

dt1 = Data table( "Reference data table.jmp");
dt2 = Data table("Data table upd");//("Current Data Table();
Col_List = dt2 << Get Column Group( "Tests");							


vc2 = Eval(
	Eval Expr(
		dt2 << distribution(

			Column( Expr( Col_List ) ),
			Horizontal Layout( 1 ),

aa_refs = Associative Array( dt1:Tests << get values, dt1:Mean << get values );

		Report( vc2[i] )[AxisBox( 1 )] << {Add Ref Line( aa_refs[Col_List[i]], "Solid", "Green", "RTS", 2 )};
	)
);*/


For( i = 1, i <= N Items( Col_List ), i++,
	If( Contains( aa_refs, char(Col_List[i]) ),
		Report( vc2 )[char(Col_List[i])][Axisbox( 1 )] << Add Ref Line( aa_refs[char(Col_List[i])], "Solid", "Green", "RTS", 2 );
	)
);
