var data = { labels : ["Eating","Drinking","Sleeping","Designing","Coding","Partying","Running"], datasets : [ { fillColor : "rgba(220,220,220,0.5)", strokeColor : "rgba(220,220,220,1)", pointColor : "rgba(220,220,220,1)", pointStrokeColor : "#fff", data : [1,1,1,1,1,1,1] } ] } var radar = new JChart.Radar(data,{ id : 'canvas1' }); radar.on('tap.point',function(data){ alert(data); }); radar.draw();
