include two series from database in a highchart chart - ajax

Question

I would like to include a series to my existing chart.
daytime = new Highcharts.Chart({
chart: {
renderTo: 'daytime_div',
defaultSeriesType: 'areaspline',
events: {
load: getData()
}
},
plotOptions: {
series: {
fillOpacity: 0.1,
lineWidth: 4,
marker: {
radius: 5,
lineWidth: 1,
lineColor: "#FFFFFF"
}
}
},
tooltip: {
formatter: function () {
var s = [];
$.each(this.points, function (i, point) {
s.push('<span style="font-size:10px;">' + point.key + '</span><br/><strong>' + point.series.name + '</strong> : ' + point.y + '</span>');
});
return s.join('<br/>');
},
shared: true,
useHTML: true
},
credits: false,
title: false,
exporting: false,
legend: {
itemDistance: 50,
itemStyle: {
color: '#333'
}
},
xAxis: {
labels: {
staggerLines: 2
}
},
yAxis: {
gridLineColor: "#e7e7e7",
title: {
text: ''
},
labels: {
x: 15,
y: 15,
style: {
color: "#999999",
fontSize: "10px"
}
},
},
series: [{
name: 'Daily',
color: "#b18eda",
data: ddata
}]
});
function getData() {
$.ajax({
url: '...',
type: "POST",
contentType: "application/json; charset=utf-8",
data: data,
success: function (f) {
var categories = [];
var series_data = [];
$.each(f.d, function (i, e) {
categories.push(e.hour);
series_data.push(parseInt(e.numa));
});
daytime.xAxis[0].setCategories(categories);
daytime.series[0].setData(series_data);
},
cache: false
});
}
The data I get from my database looks like this:
hour, numa
12 AM 1
1 AM 0
2 AM 0
3 AM 0
4 AM 0
This shows one line in the chart which is fine. I would like to add a second line that will come from a different query. The second line data will look like:
hour, numa
12 AM 0
1 AM 12
2 AM 3
3 AM 2
4 AM 2
Does anyone knows how could I include this into my second series? I have seen the sample in high charts on how to add more series. Static is pretty simple but getting the data dynamically make it more complicated to figure it out.
I am trying to find a way to add 2 series to my getData() function. Any idea will be appreciate it thanks.

Answer 1

It is explained clearly in the fiddle of the document which you shared on how to add multiple series.
series: [{
name: 'Tokyo',
data: [7.0, 6.9, 9.5, 14.5, 18.2, 21.5, 25.2, 26.5, 23.3, 18.3, 13.9, 9.6]
}, {
name: 'New York',
data: [-0.2, 0.8, 5.7, 11.3, 17.0, 22.0, 24.8, 24.1, 20.1, 14.1, 8.6, 2.5]
}, {
name: 'Berlin',
data: [-0.9, 0.6, 3.5, 8.4, 13.5, 17.0, 18.6, 17.9, 14.3, 9.0, 3.9, 1.0]
}, {
name: 'London',
data: [3.9, 4.2, 5.7, 8.5, 11.9, 15.2, 17.0, 16.6, 14.2, 10.3, 6.6, 4.8]
}]
You can pass multiple series in array and the chart can be generated.
EDIT-1
If data from different series use this fiddle.
var myComments=["First input","second comment","another comment","last comment"]
var dataValues = [29.9, 71.5, 194.1, 129.2];
var dataValues2 = [194.1, 95.6, 194.1, 29.9];
var categories = ['Jan', 'Feb', 'Mar', 'Apr'];
var n=['tooltip1','tooltip2','tooltip3','tooltip4'];
$(function () {
$('#container').highcharts({
chart: {},
tooltip: {
formatter: function () {
var serieI = this.series.index;
var index = categories.indexOf(this.x);
var comment = myComments[index];
return '-->'+comment;
}
},
xAxis: {
categories: categories
},
series: [{
data: dataValues
}, {
data: dataValues2
}]
});
});
which results in the below graph

Well you can use $.when() and load there all your ajax and in $.then() initialise chart. Second solution is prepare your query to database and return all data in single json.
