Load data into Highcharts with Ajax - ajax

Question

I am trying to update high charts on page load and on select menu change with JQUERY AJAX call. There is data being returned in [[10,1228800000],[10,1228800000]] format.The chart is blank and does not graph any of the data.
Tried several solutions posted on here but none worked.
var chart;
$(document).ready(function() {
var options = {
chart: {
renderTo: 'stats',
defaultSeriesType: 'spline'
},
title: {text:''},
xAxis: {
type: 'datetime'
},
yAxis: {},
series: []
};
var month = 'July';
$.ajax({
type: "POST",
data: "month="+month,
url: "update_visits_chart",
success: function (data) {
options.series.push(data);
chart = new Highcharts.Chart(options);
}
});
Any errors? thanks in advance.
EDIT:
MOST RECENT CODE STILL NOT WORKING:
var options = {
chart: {
renderTo: 'stats',
type: 'spline'
},
title: {
text: ''
},
xAxis: {
type:'datetime',
tickInterval: 30 * 24 * 3600 * 1000,
dateTimeLabelFormats: {
day: '%b %e'
},
labels: {
rotation: -45,
align: 'right'
}
},
yAxis: {
title: {
text: 'Number of visits'
},
min: 0
},
tooltip: {
formatter: function() {
return Highcharts.dateFormat('%b %e', this.x) +'<br />'+this.y+' visit(s)';
}
},
legend: {
enabled: true
},
credits: {
enabled: false
},
exporting: {
enabled: false
},
series: [{
name: 'Number of Visits',
data: []
}]
};
var month = 'July';
$.ajax({
type: "POST",
url: "update_visits_chart",
data: "month="+month,
success: function(data){
options.series[0].data = data;
chart = new Highcharts.Chart(options);
}
});

Answer 1

You have to use the setData methode of the series object as descriped in documentation. In your case it is options.series[0].setData(Data)
And I think you have to turn your Ajax result from string to a real object/array by using JSON.parse(data).
EDIT:
#Ricardo Lohmann: in the ajax-call he did not specify the dataType he expects in the response, so jQuery will guess the dataType. But it will not recognize a string starting with [ as JSON and I doubt his response will be served with correct mime type application/json. So specifying the correct mime type should also solve the problem. But I do not have an example of the complete ajax respons of the questioner. So I'm just guessing, too.
I'd recommend the following ajax call:
$.ajax({
type: "POST",
url: "update_visits_chart",
data: {month: month},
dataType: 'json',
success: function(data){
options.series[0].setData(data);
}
});

$.getJSON is just a shortcut for the ajax-call above, but it is less flexible because you have less options.

Answer 2

You have to set directly data to series because data is already a multidimensional array.
The following code will fix it.
Change options.series.push(data); to options.series = data;
