var ctx = document.getelementbyid('mychart').getcontext('2d');  var label2 = ['28 dec','29 dec','30 dec']; var label3 = '28 dec,29 dec,30 dec';  var data1 = '0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0';  var linechartdata = {     labels: label2,     datasets: [{         label: ' no. of clicks',         backgroundcolor: "lightblue",         data: data1     }] } var mychart = new chart(ctx, {       type: 'line',       data: linechartdata  });
