I've been trying to get some Google Charts working from some data on a
local db. I think I have got the JSON coming out properly now.
{
"cols": [
{
"id": "",
"label": "Inits",
"pattern": "",
"type": "string"
},
{
"id": "",
"label": "SalesVal",
"pattern": "",
"type": "number"
}
],
"rows": [
{
"c": [
{
"v": "IS",
"f": null
},
{
"v": "1708.6000",
"f": null
}
]
},
{
"c": [
{
"v": "NS",
"f": null
},
{
"v": "1098.8200",
"f": null
}
]
},
{
"c": [
{
"v": "RC",
"f": null
},
{
"v": "458.8200",
"f": null
}
]
}
]
}
And I'm using this as the HTML.
<html>
<head>
<!--Load the AJAX API-->
<script type="text/javascript" src="https://www.google.com/jsapi";
></script>
<script type="text/javascript" src=
"//ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
<script type="text/javascript">
// Load the Visualization API and the piechart package.
google.load('visualization', '1', {'packages':['corechart']});
// Set a callback to run when the Google Visualization API is loaded.
google.setOnLoadCallback(drawChart);
function drawChart() {
var jsonData = $.ajax({
url: "getData.php",
dataType:"json",
async: false
}).responseText;
// Create our data table out of JSON data loaded from server.
var data = new google.visualization.DataTable(jsonData);
// Instantiate and draw our chart, passing in some options.
var chart = new google.visualization.PieChart(document.getElementById(
'chart_div'));
chart.draw(data, {width: 400, height: 240});
}
</script>
</head>
<body>
<!--Div that will hold the pie chart-->
<div id="chart_div"></div>
</body>
</html>
I've gone over it a few times and can't see where I am going wrong.
Hopefully someone can help.
