I've been looking through tons of examples but I can't seem to get my code to pull out the data. The chart is blank.
I have a php file that gives the following: (date, value1, value2)
[
["2013-09-15 08:44:37",19.8,8.19],
["2013-09-15 08:47:37",18.4,7.81],
["2013-09-15 08:50:37",18.3,7.78],
["2013-09-15 08:53:37",18.1,7.77]
]
I then have the following code:
<!DOCTYPE html>
<head>
<script src="js/jquery-1.10.2.min.js"></script>
<script src="js/highcharts.js" type="text/javascript"></script>
<script>
var chart;
$(document).ready(function() {
var options = {
chart: {
renderTo: 'container',
type: 'line',
},
title: {
},
xAxis: {
type: 'datetime'
},
yAxis: {
},
series: [{
name: 'val1',
data: []
}, {
name: 'val2',
data: []
}]
};
$.getJSON('data_day.php', function(json) {
val1 = [];
val2 = [];
$.each(json, function(key,value) {
val1.push([value.time, value.val1]);
val2.push([value.time, value.val2]);
});
options.series[0].data = val1;
options.series[1].data = val2;
chart = new Highcharts.Chart(options);
});
});
</script>
</head>
<html>
I'm trying to use firebug to see where I've gone wrong. If I put
console.log(key,value)
under the $.each I can see the data:
0 ["2013-09-15 08:50:37", 18.3, 7.78]
1 ["2013-09-15 08:53:37", 18.1, 7.77]
2 ["2013-09-15 08:56:37", 18.2, 7.8]
Is there a problem with the
val1.push([value.time, value.val1]);
or
options.series[0].data = val1;
Update: Changed it to this and its now working.
val1.push([value[0], value[1]]);
val2.push([value[0], value[2]]);
