I want to use the highcharts library but it doesn't work. I've checked it in JSFiddle it is working fine but it is not working in my browser.
What is the problem? please tell me.
Here is the code:
<script src="http://code.highcharts.com/highcharts.js"></script>
<script src="http://code.highcharts.com/highcharts-more.js"></script>
<script src="http://code.highcharts.com/modules/exporting.js"></script>
<script type="text/javascript">
$(function () {
$('#container').highcharts({
chart: {
type: 'gauge',
plotBackgroundColor: null,
plotBackgroundImage: null,
plotBorderWidth: 0,
plotShadow: false
},

text: 'Speedometer'
},
pane: {
startAngle: -90,
endAngle: 90,

function (chart) {
if (!chart.renderer.forExport) {
setInterval(function () {
var point = chart.series[0].points[0],
newVal,
inc = Math.round((Math.random() - 0.5) * 20);
newVal = point.y + inc;
if (newVal < 0 || newVal > 200) {
newVal = point.y - inc;
}
point.update(newVal);
}, 3000);
}
});
});
</script>

<body>
<div id="container" style="min-width: 310px; max-width: 400px; height: 300px; margin: 0 auto"></div>
</body>
I also want to get the data from MYSQL database using AJAX which shows the current speed. I have written the query but I don't know how to use in this code.
Please tell me the method, I am new so I don't know how to use Highcharts
Here is my PHP code:
$data = mysql_query("SELECT speed FROM gps WHERE DeviceId=25 ORDER BY TIME DESC LIMIT 1")
or die(mysql_error());
$table = array();
$table['cols'] = array(
array('label' => 'Speed', 'type' => 'number')
);
$rows = array();
while ($nt = mysql_fetch_array($data))
{
$temp = array();
$temp[] = array('v' => $nt['speed']);
$rows[]['c'] = $temp;
}
$table['rows'] = $rows;
$jsonTable = json_encode($table);
please tell me how can I use this in above HighChart
