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?

Ok merci ça fonctionne correctement, mais si jamais comment peut-on fait pour mettre juste le prenom nom qu'il trouve dans le base de données ?

Dans votre exemple ça serait d'afficher que le prenom "KATIE" 

[#3]

comme ceci ça fonctionne correctement :

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