Get stats and show it in chart - PHP/HighCharts - php

Question

I have a table called "tracks",it looks like this:
id,
name,
url
hits
I have a pie charts, from highcharts, the code looks like this:
var chart;
$(document).ready(function() {
chart = new Highcharts.Chart({
chart: {
renderTo: 'chart',
plotBackgroundColor: null,
plotBorderWidth: null,
plotShadow: false
},
title: {
text: 'Where users came from, total'
},
tooltip: {
formatter: function() {
return '<b>'+ this.point.name +'</b>: '+ this.percentage +' %';
}
},
plotOptions: {
pie: {
allowPointSelect: true,
cursor: 'pointer',
dataLabels: {
enabled: false
},
showInLegend: true
}
},
credits: {
enabled: false
},
series: [{
type: 'pie',
name: 'Browser share',
data: [
['Firefox.com', 45.0],
['Default.com', 26.8],
['MSN', 12.8],
['Google.com', 8.5],
['Yahoo.com', 6.2],
['Others', 0.7]
]
}]
});
});
My question is, how can I get data from the "tracks" table (hits), and the (name) and output it in the pie chart like:
'name','hits'
And then, at last, convert # of hits, to %.

Answer 1

series: [{
type: 'pie',
name: 'Browser share',
data: [
<?php
$sql = 'select sum(hits) from tracks';
$result = mysql_query($sql);
$row = mysql_fetch_row($result);
$totalHits = $row[0];
$sql = 'select name, hits from tracks order by hits desc';
$result = mysql_query($sql);
$i = 0;
$totalOther = 0;
$maxSlices = 5;
$minPercent = 10;
while ($row = mysql_fetch_row($result))
{
$percent = row[1] / $totalHits * 100;
if (++$i <= $maxSlices && $percent >= $minPercent)
{
echo json_encode($row);
}
else
{
$totalOther += $row[1];
}
}
if ( $totalOther > 0 ) echo json_encode(array('Other', $totalOther));
?>
]
}]
if you want to refresh it thourgh ajax...
...
series: [{
type: 'pie',
name: 'Browser share',
data: getData(function(result) {return result;}),
...
and
function getData(setDataCallback)
{
$.getJSON('file.php', args, function(result) { // use of jquery for clarity.
setDataCallback(result);
});
}
in php you have to do a new file ('file.php') with the code shown in the first code block;

Answer 2

Simplest way is to query data from mySql and then sort it same as
[
['Firefox.com', 45.0],
['Default.com', 26.8],
['MSN', 12.8],
['Google.com', 8.5],
['Yahoo.com', 6.2],
['Others', 0.7]
]
Requires if you want to show chart just on page loading.
You can also use JSON.
