Using JSL script to sort a column in a data table using List Check or Value Order property

JmpStatistician — Sat, 10 Jun 2023 23:28:07 GMT

Hi all,

I'd like to use the List Check feature or the Value Order column property to custom sort a column in a datatable. This data table is created from a subset of another data table, but I am unable to get the property to custom sort the values in the data table. The relevant commands I'm using is as listed below:

dt_summary_table = (Data Table( "Name of table" )) << Make Into Data Table; // This works fine and created a datatable. 

//Using List Check property
dt_summary_table << Column( "Column_name_eg_Names" ) << Set Property(
    "List Check",
    {"OrderList_A", "OrderList_B", "OrderList_C"}
);

// Or using Value Order property 
dt_summary_table << Column( "Column_name_eg_Names" ) << Set Property(
    "Value Order",
    {"OrderList_A", "OrderList_B", "OrderList_C"}
); 

//or using List Check property
dt_summary_table << Column( "Column_name_eg_Names" ) << List Check( {"OrderList_A", "OrderList_B", "OrderList_C"} );

// Or using Value Order property 
dt_summary_table << Column( "Column_name_eg_Names" ) << Value Order( {"OrderList_A", "OrderList_B", "OrderList_C"} );

Could someone please advise what might be going bad or best way to sort the column values in custom sort order while displaying graphs/ plots etc.

I'm using JMP15 on Windows10.

In JMP 15 the structure of the column property Value Order changed. Here is an example of the new structure

names default to here(1);
dt=open("$SAMPLE_DATA\big class.jmp");

dt:sex<<set property("value order",{Custom Order({"M", "F"})});

dt << sort( by(:sex), replace table(1));

I suggest that you manually set the Value Order you want, and then use << get property("value order") to see how you need to structure your statement for your data

Thanks Jim/@txnelson very much,

This works now.

Just wondering if this new structure is documented somewhere ? I was following the documentation at https://www.jmp.com/support/help/en/15.0/#page/jmp/column-properties-3.shtml# which doens't seem to reflect the custom order syntax.

I agree with you that the documentation is in error.

Hello Jim,

When attempting to Set Property for Custom Order with a given List, the List is not interpolated/evaluated.

May I know how we can make it work with a given variable List ?

dt = Current Data Table();

order_list = { "Tony", "Robert", "Patrick", "Henry" };

dt:Names << Set Property(
	"Value Order",
	{ Custom Order( order_list ), Common Order( 0 ) }
);

In example above:

Running Custom Order( order_list ) sets the value order with a literal value named "order_list"

Running Custom Order( Eval(order_list) ) sets the value order with a literal value named "Eval"

Running Custom Order( EvalList(order_list) ) sets the value order with a literal value named "Eval List"

Literally listing the values in Custom Order without calling variable, only then it works.

This should do the trick for you

dt = Current Data Table();

order_list = {"Tony", "Robert", "Patrick", "Henry"};

Eval(
	Eval Expr(
		dt:Names << Set Property(
			"Value Order",
			{Custom Order( Expr( order_list ) ), Common Order( 0 )}
		)
	)
);
