Is it possible to dynamically update "graph title" based item selection in local data filter (including multiple selections)?

[#1]

I use the following to display "my text" at the top of my charts.

Dispatch( {}, "graph title", TextEditBox, {Set Text( "my text" )} )

However, I would like to have the item(s) selected in the local data filter to be displayed in the graph title as I select them (perhaps multiple sections as comma delimited?).

How to achieve this in JSL?

[#2]

@hogi  Your script below now works in JMP 16.2 but with the following issues.

• The chart starts with no age selected and no title shown but the last one remains shown on the chart title when all age checkboxes are unchecked.
• In the actual problem, the title starts showing only when more than one check boxes are checked.

How to resolve these two issues (unless this is my JMP version specific) ?

Names Default To Here(1);
dt = Open("$SAMPLE_DATA/Big Class.jmp");

gb = Graph Builder(
	Size( 570, 518 ),
	Show Control Panel( 0 ),
	Variables( X( :height ), Y( :weight ), Overlay( :sex ) ),
	Elements( Points( X, Y, Legend( 1 ) ), Smoother( X, Y, Legend( 2 ) ) ),
	Local Data Filter(
		Conditional,
		Add Filter(
			columns( :sex, :age, :weight ),
			Display( :sex, "Check Box Display" ),
			Display( :age, "Check Box Display" )
		)
	),
	SendToReport( Dispatch( {}, "graph title", TextEditBox, {Set Text( "" )} ) )
);

ldf = Current Report()["Local Data Filter"] << get scriptable object;

changeTitle = Function( {this},
	print(this);
	ldfText = Regex(ldf << get where clause(),"\( *(:age == .*?)\)","\1");
	(Report( gb ) << XPath( "//TextEditBox" ))[1] << Set Text( ldfText );
);
fsh = ldf << Make Filter Change Handler(
	changeTitle();
);

You are right.
If Regex doesn't find the age info, it returns missing.

So, after

ldfText = Regex(ldf << get where clause(),"\( *(:age == .*?)\)","\1");

please add

if(ismissing(ldfText),ldfText = "all ages");

to fix the issue.

If you just select one entry at a time, you could use the page dropzone to automatically label the plot:
[if multiple entries are selected, the respective data gets split across multiple pages]

Names Default To Here(1);
dt = Open("$SAMPLE_DATA/Big Class.jmp");

Graph Builder(
	Variables( X( :height ), Y( :weight ), Page( :age ), Overlay( :sex ) ),
	Elements( Points( X, Y, Legend( 1 ) ), Smoother( X, Y, Legend( 2 ) ) ),
	Local Data Filter(
		Add Filter(
			columns( :sex, :age, :weight ),
			Where( :age == 14 )
		)
	)
);

My script below (for the actual case) appears to be triggering only after the second check box selection. Any leads as to why would be useful. 

changeTitle = Function( {this},
	print(this);
   	ldfText = Regex(ldf << get where clause(),"\( *(:Parameter == .*?)\)","\1");
	if(ismissing(ldfText),ldfText = " Selected Test Parameter ");
	(Report( gb ) << XPath( "//TextEditBox" ))[4] << Set Text(ldfText);
);

fsh = ldf << Make Filter Change Handler(
	changeTitle();
);

[#6]

Oh, sorry, I always started by selecting the age - and then I missed that the title didn't update for the case of one age selection + something else.

If there is just a single age selection, there is no need for additional brackets.
So, how about skipping the first bracket ?

NB: please don't use inverse with this version

changeTitle = Function( {this},
	print(this);
	print(ldf << get where clause());
	ldfText = Regex(ldf << get where clause(),"(:age == .*?)\)","\1");
	if(ismissing(ldfText),ldfText = "any text you want");
	(Report( gb ) << XPath( "//TextEditBox" ))[1] << Set Text( ldfText );
);

@hogi . Does not work for me in JMP 16.2.0. I have opened a new thread on this with a better example on what is not working here (link).

[#8]

Actually, this version should with Jmp 16.2.0:

@hogi  The following is (almost) working and the current issues reported here.

ldfText = Regex(ldf << get where clause(),"\(?\s*(:age == .*?)\)","\1");

. 

[#10]

Bonjour à tous,

Comment on fait pour mettre une deuxième colonne dans le remplissage des titres automatiques ?

La colonne "name" ne fait pas parti du filtre des données locales, mais en fonction de la sélection des "ages" dans le filtre on aurait tous les noms correspondants à ces "ages" dans le titre du graphique. Tout ça de façon dynamique.

ldfText = Regex(ldf << get where clause(),"\( *(:age == .*?)\)","\1");

[#11]

Here is one approach in getting all of the names listed

changeTitle = Function( {this},
	Eval( Parse( "theRows = dt << get rows where" || Substr( ldf << get where clause(), 13 ) ) );
	If( Length( theRows ) > 0,
		ldfText = Concat Items( :name[theRows],"," ),
		ldfText = "All Names"
	);
	(Report( gb ) << XPath( "//TextEditBox" ))[1] << Set Text( ldfText );
);
