Hi All, I'm trying to draw a chart based off some mysql data, and for some reason, the chart is blank.
the code is here :- <html> <head> <script type="text/javascript" src=" https://www.gstatic.com/charts/loader.js";></script> <script type= "text/javascript" src=" http://ajax.googleapis.com/ajax/libs/jquery/1.8.2/jquery.min.js";></script> </head> <body> <div id="curve_chart" style="width: 900px; height: 500px" ></div> <script type="text/javascript"> google.charts.load('current', { 'packages':['corechart']}); google.charts.setOnLoadCallback(drawChart); function drawChart() { var data = new google.visualization.DataTable([ data. addColumn(timeofday,'Time'); data.addColumn(number,'Probe 1'); data. addColumn(number,'Probe 2'); data.addColumn(number,'Probe 3'); data. addColumn(number,'Probe 4'); data.addRows([ [ {"rows":[{"c":[{"v":"03:02:07" },{"v":"270.26"},{"v":"298.40"},{"v":"111.54"},{"v":"228.06"}]},{"c":[{"v": "03:28:42"},{"v":"273.23"},{"v":"190.43"},{"v":"245.69"},{"v":"283.21"}]},{ "c":[{"v":"07:26:04"},{"v":"144.33"},{"v":"217.26"},{"v":"206.53"},{"v": "167.68"}]},{"c":[{"v":"12:13:20"},{"v":"153.15"},{"v":"277.23"},{"v": "167.20"},{"v":"240.88"}]}]} ] ]); var options = { title: 'Recorded Temperatures', legend: { position: 'bottom' }, width: 900, height: 500, hAxis: { format: 'hh:mm:ss' } }; var chart = new google.visualization. LineChart(document.getElementById('curve_chart')); chart.draw(data, options ); } </script> </body> </html> The data shown in data.addRows([ ... is being generated by a php echo, which is a json array. if these values are hard coded into the table, it's fine. If I pull it from the php in this way, the chart doesn't render. -- You received this message because you are subscribed to the Google Groups "Google Visualization API" group.
