Convert Highchart to multiple y axis - php

Question

I have a working graph using Highcharts with data from a mySQL database. I need it now to view the lines on different axis so that the chart is better laid out.
Here's my code and JSFiddle for the graph with my data:
http://jsfiddle.net/petenaylor/tGfau/3/
(function($){ // encapsulate jQuery
$(function() {
var seriesOptions = [],
yAxisOptions = [],
seriesCounter = 0,
names = ['Electric', 'Oil', 'Gas'],
colors = Highcharts.getOptions().colors;
$.each(names, function(i, name) {
$(function() {
$.getJSON('http://www.highcharts.com/samples/data/jsonp.php?filename=aapl-c.json&callback=?', function(data) {
// Create the chart
window.chart = new Highcharts.StockChart({
chart : {
renderTo : 'container',
zoomType: 'x'
},
rangeSelector : {
selected : 12
},
title : {
text : 'Energy Prices'
},
series : [{
name : 'Electric',
<?php
$result = mysql_query (" SELECT * FROM energyprices ORDER BY id ASC") or die (mysql_error());
while ($row = mysql_fetch_array($result)) {
extract($row);
$date = strtotime($row['pDate']);
$date = $date."000"; // convert from Unix timestamp to JavaScript time
$data1[] = "[$date, $electric]";
}
?>
data: [<?php echo join($data1, ',') ?>],
tooltip: {
valueDecimals: 2
}
},{
name : 'Oil',
<?php
$result = mysql_query (" SELECT * FROM energyprices ORDER BY id ASC") or die (mysql_error());
while ($row = mysql_fetch_array($result)) {
extract($row);
$date = strtotime($row['pDate']);
$date = $date."000"; // convert from Unix timestamp to JavaScript time
$data2[] = "[$date, $oil]";
}
?>
data: [<?php echo join($data2, ',') ?>],
tooltip: {
valueDecimals: 2
}
},{
name : 'Gas',
<?php
$result = mysql_query (" SELECT * FROM energyprices ORDER BY id ASC") or die (mysql_error());
while ($row = mysql_fetch_array($result)) {
extract($row);
$date = strtotime($row['pDate']);
$date = $date."000"; // convert from Unix timestamp to JavaScript time
$data3[] = "[$date, $gas]";
}
?>
data: [<?php echo join($data3, ',') ?>],
tooltip: {
valueDecimals: 2
}
}]
});
});
});
});
// create the chart when all data is loaded
function createChart() {
chart = new Highcharts.StockChart({
chart: {
renderTo: 'container'
},
rangeSelector: {
selected: 4
},
/*yAxis: {
labels: {
formatter: function() {
return (this.value > 0 ? '+' : '') + this.value + '%';
}
},
plotLines: [{
value: 0,
width: 2,
color: 'silver'
}]
},*/
yAxis: [{ // Primary yAxis
labels: {
formatter: function() {
return (this.value > 0 ? '+' : '') + this.value + '%';
},
style: {
color: '#89A54E'
}
},
title: {
text: 'Electric',
style: {
color: '#89A54E'
}
},
opposite: true
}, { // Secondary yAxis
gridLineWidth: 0,
title: {
text: 'Oil',
style: {
color: '#4572A7'
}
},
labels: {
formatter: function() {
return this.value;
},
style: {
color: '#4572A7'
}
}
}, { // Tertiary yAxis
gridLineWidth: 0,
title: {
text: 'Gas',
style: {
color: '#AA4643'
}
},
labels: {
formatter: function() {
return this.value;
},
style: {
color: '#AA4643'
}
},
opposite: true
}],
plotOptions: {
series: {
compare: 'percent'
}
},
tooltip: {
pointFormat: '<span style="color:{series.color}">{series.name}</span>: <b>{point.y}</b> ({point.change}%)<br/>',
valueDecimals: 2
},
series: seriesOptions
});
}
});
})(jQuery);
As you can see this works as it should, however, I need this to function like the below example. It's important that I have the y axis showing the values and the zoom must work. I have tried to adapt the below code with my own data but I get the issue unresponsive script. I think my data could be too much for the chart to handle.

$(function () {
var chart;
$(document).ready(function() {
chart = new Highcharts.Chart({
chart: {
renderTo: 'container',
zoomType: 'xy'
},

},
subtitle: {

},
xAxis: [{
categories: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun',
'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec']
}],
yAxis: [{ // Primary yAxis

formatter: function() {
return this.value +'°C';
},

}
},

}]
});
});
});
Can anyone help?
Many thanks

I think this is what you want: http://jsfiddle.net/mxrhS/
I did it by defining 3 yaxis, and then setting each series to use a different yaxis:
yAxis:[{opposite:false},{opposite:true},{opposite:true,offset:50}],
and
series: [{
name: 'Electric',
yAxis:0,
