A mixed chart with splines and points. The points get special highlight and noHighlight-methods in order to have an animated highlighting with a growing resp. decreasing radius.

JavaScript code to produce this chart

 var board = JXG.JSXGraph.initBoard('jxgbox', {boundingbox: [-1, 10, 11, -2]});
 board.suspendUpdate();

 var axisy = board.create('axis', [[0,0], [0,1]], {strokeColor:'black'});
 var chart = board.create('chart', dataArr, {chartStyle:'spline,point',labels:dataArr});
 chart[0].setProperty({strokeColor:'#32CD32',highlightStrokeColor:'#32CD32',strokeWidth:3});
 board.unsuspendUpdate(); 
 var i, animate;
 for(i=0; i<chart[1].length; i++) {
     chart[1][i].setProperty({face:'square',size:5,strokeColor:'#32CD32',fillColor:'#EEE9BF',strokeWidth:3});
     chart[1][i].highlight = function() {    
         var ms = 200, to = 10, from = 5, difference, el = this, start = new Date, animate;
         difference = (to-from)/ms;

         function step() {
             var time = new Date - start, current;
