The JavaScript code

board.suspendUpdate();           

var s = board.createElement('slider', [[8,7],[11,7],[1,1,1.5]], {name:'S',strokeColor:'black',fillColor:'white'});
var f = [function(){return (s.Value()*4.5).toFixed(2);},
         function(){return (s.Value()*(-1)).toFixed(2);},
         function(){return (s.Value()*3).toFixed(2);},
         function(){return (s.Value()*2).toFixed(2);},
