My JSON data is:{ "cols":
[{"id":"","label":"Date2","pattern":"","type":"number"},
{"id":"","label":"OK Count","pattern":"","type":"date"} ], "rows": [
{"c":[{"v": 2 ,"f": null},{"v": "Date(2015,04,09) ","f": null }]},
{"c":[{"v": 10 ,"f": null},{"v": "Date(2015,04,10) ","f": null }]},
{"c":[{"v": 4 ,"f": null},{"v": "Date(2015,04,11) ","f": null }]},
{"c":[{"v": 4 ,"f": null}, {"v": "Date(2015,04,20)","f": null }]} ] }
Part of my script is:
<!--Load the AJAX API-->
<script type="text/javascript" src="http://www.google.com/jsapi";></script>
<script type="text/javascript" src="jquery-1.9.1.min.js"></script>
<script type="text/javascript">
// Load the Visualization API and the piechart,table package.
google.load('visualization', '1', {'packages':['corechart']});
function drawItems(num) {
var jsonPieChartData = $.ajax({
url: "getdata.php",
data: "q="+num,
dataType:"json",
async: false
}).responseText;
// Create our data table out of JSON data loaded from server.
var piechartdata = new google.visualization.DataTable(jsonPieChartData);
// Instantiate and draw our pie chart, passing in some options.
var chart = new
google.visualization.LineChart(document.getElementById('chart_div'));
chart.draw(piechartdata, {
width: 800,
height: 600,
pointSize:5,
chartArea: { left:"10%",top:"10%",width:"80%",height:"80%" },
legend: {position:'top'},
hAxis: {
title: "Date1"
}
});
}
I don't think so that there is any error in it. But it gives error
"Undefined is not a function" all the time. What could be the reason of it?
