Retrieve series name and data with getjson - highcharts

I'm trying to retrieve from a JSON formatted file this series name and data
[
{ "name":"gfs00", "data": [ [1359676800000, 30], [1359687600000, 32]]
},
{ "name":"gfs06", "data": [ [1359676800000, 28], [1359687600000, 29]]
}
]
Here's the highchart code:
var data_temp;
$.getJSON('dati/performance_gfs/precipitazioni/pioggia_live_data.php',
{ run: runs_gfs} ,function(data_temp){
for (var i = 0; i <data_temp.length ;i++){
chart.addSeries({
data:data_temp,
});
}
});
$(document).ready(function() {
chart = new Highcharts.Chart({
chart: {
renderTo: 'container_temperatura_windchill_heatindex',
defaultSeriesType: 'line',
zoomType: 'x',
},
title: {
text: 'Ensemble'
},
xAxis: {
type: 'datetime'
},
yAxis: [{ // Primary yAxis
id:0,
labels: {
formatter: function() {
return this.value +'°C';
},
style: {
color: '#89A54E'
}
},
title: {
text: 'Temperature',
style: {
color: '#89A54E'
}
}
}],
plotOptions: {
line: {
lineWidth: 1,
states: {
hover: {
lineWidth: 2
}
},
marker: {
enabled: false,
states: {
hover: {
enabled: true,
symbol: 'circle',
radius: 5,
lineWidth: 1
}
}
},
pointInterval: 24 * 3600000, // one hour
pointStart: Date.UTC(2012, 9, 6, 0, 0, 0)
}
},
tooltip: {
formatter: function() {
return '<b>'+ this.series.name +'</b><br/>'+
Highcharts.dateFormat('%d-%m-%Y %H:%M', this.x)+'<br/>'+
this.y;
}
},
series: []
});
});
}
As can be seen I don't know how to assign the series names and data from the JSON file which is correct what I need is something like http://jsfiddle.net/vXdxv/1/

Try the following:
for (var i = 0; i <data_temp.length ;i++){
chart.addSeries(data_temp[i], false);
});
chart.redraw();

Highcharts marker for single point won't display

I loop over the data and create a marker if the condition is met. All the points on the graph appear, but where the marker should be, because it met the condition, an empty point is displayed only and there is a gap in the chart.
for (i = 0; i < data.length; i++) {
if (parseFloat(data[i][2]) >= 0.99999) {
y_point = {
'marker': {
'enabled':true,
'lineWidth': 3,
'radius': 10,
'symbol': 'triangle'
},
'y': parseFloat(data[i][1])
}
} else {
y_point = parseFloat(data[i][1])
}
metricData.push([moment(data[i][0]).utc().unix() * 1000, y_point])
}

Highchart shows only points

I'm a newbie in html and javascript.
I'm Trying to make a spline chart with csv data file but the chart only shows the points.
Could anyone help me? Thanks in advance.
The parsing csv code follows below:
jQuery.get(dataFilePath, null, function(csv, state, xhr) {
var lines = [],
date,
// set up the two data series
lightLevels = [];
// inconsistency
if (typeof csv !== 'string') {
csv = xhr.responseText;
}
// split the data return into lines and parse them
csv = csv.split(/\n/g);
jQuery.each(csv, function(i, line) {
// all data lines start with a double quote
line = line.split(',');
date = parseInt(line[0], 10)*1000;
lightLevels.push([
date,
parseFloat(line[1], 10)
]);
});
options.series[0].data = lightLevels;
chart = new Highcharts.Chart(options);
});
});
});
The graph code is:
chart: {

how do I get two highcharts on one page?

I have two charts that I am trying to load on separate div's on the same page, they are similar but one is a drill down and the other isn't. I have tried wrapping the entire function with var chart = $('#review').highcharts({ but it doesn't work.
The two charts are below:
$(function () {
var colors = Highcharts.getOptions().colors,
categories = ['Metric 1', 'Metric 2', 'Metric 3','metric 4'],
name = 'Votes',
data = [{
y: 1,
color: colors[0],
}, {
y: 2,
color: colors[1],
}, {
y: 3,
color: colors[2],
},{
y: 5,
color: colors[3],
}];
function setChart(name, categories, data, color) {
chart.xAxis[0].setCategories(categories, false);
chart.series[0].remove(false);
chart.addSeries({
name: name,
data: data,
color: color || 'white'
}, false);
chart.redraw();
}
var chart = $('#review').highcharts({
chart: {
type: 'column'
},
title: {
text: 'Review breakdown'
},
xAxis: {
categories: categories
},
tooltip: {
formatter: function() {
var point = this.point,
s = this.x +'<br><b>'+ this.y +' stars</b><br/>';
return s;
}
},
series: [{
name: name,
data: data,
color: 'white'
}],
exporting: {
enabled: false
},
legend: {
enabled: false
},
credits: {
enabled: false
}, yAxis: {min: 0, max: 5,
title: {text: 'Star Rating'}
}
})
.highcharts(); // return chart
});
$(function () {
var colors = Highcharts.getOptions().colors,
categories = ['positive', 'negative', 'sum'],
name = 'Votes',
data = [{
y: 55.11,
color: colors[0],
drilldown: {
name: 'Positive votes',
categories: ['Users', 'Admin', 'Anonymous'],
data: [10.85, 7.35, 33.06],
color: colors[0]
}
}, {
y: -7.15,
color: colors[3],
drilldown: {
name: 'Negative votes',
categories: ['Users', 'Admin', 'Anonymous'],
data: [-4.55, -1.42, -0.23],
color: colors[3]
}
}, {
y: 2.14,
color: colors[4],
drilldown: {
name: 'Total votes',
categories: ['Users', 'Admin', 'Anonymous'],
data: [ 0.12, 0.37, 1.65],

}
}];
function setChart(name, categories, data, color) {
chart.xAxis[0].setCategories(categories, false);
chart.series[0].remove(false);
chart.addSeries({
name: name,
data: data,
color: color || 'white'
}, false);
chart.redraw();
}
var chart = $('#votes').highcharts({
chart: {
type: 'column'
},
title: {
text: 'Vote breakdown'
},
subtitle: {
text: 'Click the columns to view breakdown.'
},
xAxis: {
categories: categories
},
yAxis: {
title: {
text: 'Total votes'
}
},
plotOptions: {
column: {
cursor: 'pointer',
point: {
events: {
click: function() {
var drilldown = this.drilldown;
if (drilldown) { // drill down
setChart(drilldown.name, drilldown.categories, drilldown.data, drilldown.color);
} else { // restore
setChart(name, categories, data);
}
}
}
},

if (point.drilldown) {
s += 'Click to view '+ point.category +' breakdown';
} else {
s += 'Click to return';
}
return s;
}
},

color: 'white'
}],
exporting: {
enabled: false
},
legend: {
enabled: false
},

enabled: false
},
})
.highcharts(); // return chart
});
If you're trying to get two charts on one page then it is VERY simple.
<div id="chart-A" class="chart"></div>
<div class="spacer"></div>
<div id="chart-B" class="chart"></div>
CSS - Just to make the example a little easier on the eyes
.chart {
height: 200px;
}
.spacer {
height: 20px;
}
JavaScript
$(function() {
// If you need to specify any global settings such as colors or other settings you can do that here
// Build Chart A
$('#chart-A').highcharts({
chart: {
type: 'column'
},
title: {
text: 'Chart A'
},
xAxis: {
categories: ['Jane', 'John', 'Joe', 'Jack', 'jim']
},
yAxis: {
min: 0,
title: {
text: 'Apple Consumption'
}
},
legend: {
enabled: false
},
credits: {
enabled: false
},
tooltip: {
shared: true
},
series: [{
name: 'Apples',
data: [5, 3, 8, 2, 4]
}]
});
// Build Chart B
$('#chart-B').highcharts({
chart: {
type: 'column'
},
title: {
text: 'Chart B'
},
xAxis: {
categories: ['Jane', 'John', 'Joe', 'Jack', 'jim']
},
yAxis: {
min: 0,
title: {
text: 'Miles during Run'
}
},
legend: {
enabled: false
},
credits: {
enabled: false
},
tooltip: {
shared: true
},
series: [{
name: 'Miles',
data: [2.4, 3.8, 6.1, 5.3, 4.1]
}]
});
});
Here's a JSFiddle: http://jsfiddle.net/engemasa/7cvCX/
I am not really sure what some of your code is trying to do - seems a little needlessly complicated, FWIW
AS to how to make multiple charts on the same page - you do it just like you would make one chart on a page, just do it more than once :)
and make sure you have different container element ids - otherwise you are just overwriting one chart with the next.
One example of multiple charts on a page:

Highcharts JSON load issue

I have a sample Highchart that I'm try to load JSON data without any luck. I see the data return in firebug but the chart bar and line doesn't get drawn. You can see my chart here jsfiddle.net. I know I'm missing something, but I can't seem to put my fingers on it. Any help would greatly appreciated, thank you in advance.
This is my code:
$(function() {

}]
};
});
$.getJSON('data.cfm', function(json) {
options.series = json;
var chart = new Highcharts.Chart(options);
})
Here's what data.cfm return:
[[9233,14837,11442,8080,10302,5373,2450,9612,18656,8999],[7963,7845,8646,5130,2570,8936,17487,9141,6728,6046]];
Shoulnt it be?
options.series[0].data=json[0];
options.series[1].data=json[1];
