There are many examples of updating Google Gauge dynamically using javascript, but I want to do it at certain times using a call (function?) from PHP.
Here is my code: <html> <head> <title>Google Gauge Dynamic Update using PHP</title> <script type='text/javascript' src='https://www.google.com/jsapi'></ script> <script type='text/javascript'> google.load('visualization', '1', {packages:['gauge']}); google.setOnLoadCallback(drawChart); function drawChart() { var data = new google.visualization.DataTable(); data.addColumn('string', 'Label'); data.addColumn('number', 'Value'); data.addRows([ ['Processing', 0] ]); var options = { width: 400, height: 220, greenFrom: 66, greenTo: 100, yellowFrom:33, yellowTo: 66, redFrom:0, redTo:33, minorTicks: 5 }; var chart = new google.visualization.Gauge(document.getElementById('chart_div')); chart.draw(data, options); google.visualization.events.addListener(gauge, 'select', function() { } } </script> </head> <body> <div id='chart_div'></div> <?php sleep(2); // Update the graph to 10% // Somehow update the gauge to 10% sleep(5); // Update the graph to 30% // Somehow update the gauge to 30% // Etc... ?> </body> </html> How do I call the listener from PHP? I need a code example. I know where all the Google Chart Documentation is.
