HighChart Pie Dynamic JSON in Codeigniter - ajax

Question

Any help for this? The problem is I cannot get the data in pie. Any ideas? I tried to echo it outside the pie graph view, and the data appears in JSON as [{"Terminal":"13"}]. The Hightchart needs the data as ["Sample", 2]? Any suggestion sir on how to convert it like that? Thanks.
Heres my code:
VIEW
$(document).ready(function () {
$(function () {
var chart;
// Build the chart
$('.widget-lower-left#widget').highcharts({
chart: {
plotBackgroundColor: null,
plotBorderWidth: null,
plotShadow: false
},
title: {
text: 'Availability'
},
tooltip: {
pointFormat: '{series.name}: <b>{point.percentage}%</b>',
percentageDecimals: 1
},
plotOptions: {
pie: {
allowPointSelect: true,
cursor: 'pointer',
dataLabels: {
enabled: false
},
showInLegend: true
}
},
series: [{
type: 'pie',
name: 'Availability',
data: []
}]
});
});
function requestData() {
$.ajax({
url: 'home',
datatype: "json",
success: function(data) {
alert(data);
console.log(data);
chart.series[0].setData(data);
},
cache: false
});
};
});
then in the MODEL
$results = $this->db->query("SELECT COUNT(get_jeeps_availability) as Terminal FROM get_jeeps WHERE get_jeeps_availability = 'Terminal'");
return $results->result_array();
in the CONTROLLER
public function index()
{
$data['pie'] = json_encode($this->get_model->dashboard_jeep_widget());
$this->load->view('home',$data);
}

In requestData() function, before setting data, preprocess 'data' that way:
var newData = [];
for( var i = 0, len = data.length; i < len; i++ ) {
var item = data[i];
for(var j in item){
newData.push([j,item[j]]);
}
}
chart.series[0].setData(newData);
