I have this google charts code which works fine: <script type="text/javascript" src="https://www.google.com/jsapi";></script> <script type="text/javascript" async> google.load("visualization", "1", {packages:["corechart"]}); var t1 = 'IndexTitle' var t2 = 'IndicatorTitle' google.setOnLoadCallback(function(){drawChart1(t1)}); google.setOnLoadCallback(function(){drawChart2(t2)}); function drawChart1(t){ var data = new google.visualization.DataTable(); data.addColumn('string','Date'); data.addColumn('number','Close'); data.addColumn({type: 'string', role: 'tooltip'}); data.addRows([ChartIndexData...........]); var options = { title: t, colors:['black'], legend: {position: 'none'}, chartArea:{left:60,top:20,width:'90%',height:'90%'} }; var chart = new google.visualization.LineChart(document.getElementById('chart1_div')); chart.draw(data, options); } function drawChart2(t){ var data = new google.visualization.DataTable(); data.addColumn('string', 'Date'); data.addColumn('number', ''); data.addColumn({type: 'string', role: 'tooltip'}); data.addRows([ChartIndicatorData...................]); var options = { title: t, legend: {position: 'none'}, chartArea:{left:60,top:20,width:'90%',height:'60%'} }; var chart = new google.visualization.LineChart(document.getElementById('chart2_div')); chart.draw(data, options); }<% </script>
The problem is when I test the page on Google PageSpeed insite the score is 49/100 because of the script above: Remove render-blocking JavaScript:https://www.google.com/jsapi https://www.google.com/…ile=visualization&v=1&packages=corechart https://www.google.com/…at+en,default+en,ui+en,corechart+en.I.js Optimize CSS Delivery of the following: https://www.google.com/…bdd6ab2d343a51d49841bf93d022fb/ui+en.css https://ajax.googleapis.com/…static/modules/gviz/1.0/core/tooltip.css As I understand I have to load javascript Asynchronous or defer the loading. How do I fix it. -- You received this message because you are subscribed to the Google Groups "Google Visualization API" group.
