Display chart from ms sql using highchart - php

Question

I'm trying to display data from MSSQL. I saw an example at http://www.blueflame-software.com/blog/using-highcharts-with-php-and-mysql.
Value of Y Axis already good, but the X axis cannot display on my chart, so the value of chart only in 0 Xaxis,
data.php
mssql_select_db("CU-CAB01", $con);
$result = mssql_query("select count(nba) sumnba, datein from tbl_anggota where tgl_masuk > '2012-06-01'group by tgl_masuk");
while($row = mssql_fetch_array($result)) {
echo $row['tgl_masuk'] . "\t" . $row['jumlah']. "\n";
index.php
<script type="text/javascript" src="js/jquery-1.7.1.min.js" ></script>
<script type="text/javascript" src="js/highcharts.js" ></script>
<script type="text/javascript" src="js/themes/dark-blue.js"></script>
<script type="text/javascript">
var chart;
$(document).ready(function() {
var options = {
chart: {
renderTo: 'container',
defaultSeriesType: 'line',
marginRight: 130,
marginBottom: 25
},
title: {
text: 'Hourly Visits',
x: -20 //center
},
subtitle: {
text: '',
x: -20
},
xAxis: {
type: 'datetime',
tickInterval: 10000 * 1000, // one hour
tickWidth: 0,
gridLineWidth: 1,
labels: {
align: 'center',
x: -3,
y: 20,
formatter: function() {
return Highcharts.dateFormat('%e', this.value);
}
}
},
yAxis: {
tickInterval: 2,
title: {
text: 'Anggota'
},
plotLines: [{
value: 0,
width: 1,
color: '#808080'
}]
},
tooltip: {
formatter: function() {
return Highcharts.dateFormat('%l%p', this.x-(1000*3600)) +'-'+ Highcharts.dateFormat('%l%p', this.x) +': <b>'+ this.y + '</b>';
}
},
legend: {
layout: 'vertical',
align: 'right',
verticalAlign: 'top',
x: -10,
y: 100,
borderWidth: 0
},
series: [{
name: 'Count'
}]
}
jQuery.get('data.php', null, function(tsv) {
var lines = [];
traffic = [];
try {
// split the data return into lines and parse them
tsv = tsv.split(/\n/g);
jQuery.each(tsv, function(i, line) {
line = line.split(/\t/);
date = Date.parse(line[0] +' UTC');
traffic.push([
date,
parseInt(line[1].replace(',', ''),10)
]);
});
} catch (e) { }
options.series[0].data = traffic;
chart = new Highcharts.Chart(options);
});
});
</script>
and my data in tbl_anggota query result like this
sumnba datein
1 2012-07-03 00:00:00.000
4 2012-07-04 00:00:00.000
5 2012-07-05 00:00:00.000
5 2012-07-06 00:00:00.000
2 2012-07-16 00:00:00.000
5 2012-07-17 00:00:00.000
1 2012-07-18 00:00:00.000
2 2012-07-19 00:00:00.000
I think my mistake in parsing data with jquery on datein field, so my Xaxis only in null value..
Can someone get my chart to display the Xaxis value?

Answer 1

If you output query is like above, you have your X and Ys reversed in your parsing. The date field is after the count field:
// split the data return into lines and parse them
tsv = tsv.split(/\n/g);
jQuery.each(tsv, function(i, line) {
line = line.split(/\t/);
date = Date.parse(line[1] +' UTC'); //your datin is after the '\t'
traffic.push([
date,
parseInt(line[0].replace(',', ''),10) //your count is before the '\t'
]);
});
And please, please fix the empty catch block. Ignore errors in a critical section of code is never a good idea.
