How to show multiple graphs in drilldown (highcharts)?

NET MVC Project, where I use Highcharts. In my charts i have columns and a spline.
I have already implemented drilldown for my chart and it works perfectly, but only for the columns. On the first level the columns and the spline is shown, but when I trigger drilldown only the columns are shown. data2 should be the spline.
var mychart = Highcharts.chart('container', {
chart: {
zoomType: 'xy',
spacingBottom: 40,
spacingTop: 40,
events: {
// DRILLDOWN
drilldown: function (e) {
//Some variables id, func
$.getJSON(`/Home/GetDataForMinuteDrilldown?id=${id}&function=${func}`, function (data) {
console.log(data);
var durationArrMinutes = data.map(function (item) {
return item['minuteavg'];
});
var errorArrayMinutes = data.map(function (item) {
return item['errorsperminute']
});
var minuteArray = data.map(function (item) {
return {
name: drill + ":" + item['minute'],
y: item['minuteavg'],
drilldown: item['minute']
};
});
data2 = {
name: 'Errors per Minute',
type: 'spline',
data: errorArrayMinutes,
tooltip: {
valueSuffix: ' '
}
}
data = {
name: 'Average Duration per Minute',
type: 'column',
yAxis: 1,
data: minuteArray,
tooltip: {
valueSuffix: ' ms'
},
data2 //I think this is the error, but I i know no solution
}
console.log('Data:')
console.log(data);
mychart.hideLoading();
mychart.addSeriesAsDrilldown(e.point, data);
});
}
}
},
title: {
text: 'Performance and Error Analytics'
},
subtitle: {
text: 'Analytics of: ' + func
},
xAxis: [{
type: 'category',
crosshair: true
}],
yAxis: [{ // Primary yAxis
labels: {
format: '{value}',
style: {
color: Highcharts.getOptions().colors[1]
}
},
title: {
text: 'Errors',
style: {
color: Highcharts.getOptions().colors[2]
}
}
}, { // Secondary yAxis
title: {
text: 'Duration in ms',
style: {
color: Highcharts.getOptions().colors[0]
}
},
labels: {
format: '{value} ms',
style: {
color: Highcharts.getOptions().colors[0]
}
},
opposite: true
}],
tooltip: {
shared: true
},
legend: {
layout: 'vertical',
align: 'center',
x: 0,
verticalAlign: 'bottom',
y: 50,
floating: true,
backgroundColor:
Highcharts.defaultOptions.legend.backgroundColor || // theme
'rgba(255,255,255,0.25)'
},
series: [{
name: 'Average Duration per Hour',
type: 'column',
yAxis: 1,
data: durationPerHourArray,
tooltip: {
valueSuffix: ' ms'
}
}, {
name: 'Errors',
type: 'spline',
data: errorArray,
tooltip: {
valueSuffix: ' '
}
}],
drilldown: {
activeAxisLabelStyle: {
textDecoration: 'none',
fontStyle: 'normal',
color: 'black'
},
series: []
}
});

The addSeriesAsDrilldown method allows to add only one series to drilldown. From source code:
Chart.prototype.addSeriesAsDrilldown = function (point, options) {
this.addSingleSeriesAsDrilldown(point, options);
this.applyDrilldown();
};
Instad of addSeriesAsDrilldown, you can use internal addSingleSeriesAsDrilldown method to add both series and call applyDrilldown:
mychart.addSingleSeriesAsDrilldown(e.point, data);
mychart.addSingleSeriesAsDrilldown(e.point, data2);
mychart.applyDrilldown();

Highchart: how to update a dynamic chart by clicking on a button?

I intend to have a button on my web page so that upon clicking a button, a point will be added to a chart without redrawing the whole chart (the chart is a modified version of this http://www.highcharts.com/demo/dynamic-update). However, my current code is not working.
Here is the code in concern: http://jsfiddle.net/wtvaz9gc/7/
var series;
$(function drawCharts(numberOfPoint) {
// if(typeof chartData == undefined){
// chartData = $(dataStore.getXml());
// }
$("#b").click(function(){
series.addPoint([3,3]);
})
$(document).ready(function () {
Highcharts.setOptions({
global: {
useUTC: false
}
});
$('#container').highcharts({
chart: {
type: 'line',
animation: Highcharts.svg, // don't animate in old IE
marginRight: 10,
events: {
load: function () {
series = this.series[0];
// window.myGlobal1 = this.series[0].data[this.series[0].data.length - 1].y;
// console.log(window.myGlobal1 + " " + this.series[0].data[this.series[0].data.length - 1].y);
},
}
},
title: {
text: ''
},
xAxis: {
title: {
text: 'Jahre'
},
// gridLineWidth: 0,
// lineWidth:1,
startOnTick: true,
tickPixelInterval: 40,
min: 0,
max: 10,
plotLines: [{
value: 0,
width: 1,
color: '#808080'
}]
},
yAxis: {
title: {
text: 'Vermögen(in EUR)'
},
labels: {
enabled: true
},
min: 0,
max: 100,
plotLines: [{
value: 0,
width: 1,
color: '#808080'
}]
},
tooltip: {
enabled : false,
formatter: function () {
return '<b>' + this.series.name + '</b><br/>' +
Highcharts.dateFormat('%Y-%m-%d %H:%M:%S', this.x) + '<br/>' +
Highcharts.numberFormat(this.y, 2);
}
},
legend: {
enabled: false
},
exporting: {
enabled: false
},
series: [{
name: 'Random data',
data: ($(function () {
// generate an array of random data
var data = [],
time = (new Date()).getTime(),
i, preValue;
for (i = 0; i < numberOfPoint; i += 1) {
if(i == 0){
data.push({
x: i,
y: 10
});
} else {
data.push({
x: i,
y: chartData["wealth"][0][i]
});
}
}
// showMsg(data);
// console.log(data);
return data;
}()))
}]
});
});
});
When I tries to run it in chrome, I got the following error report:
highcharts.js:Uncaught TypeError: i.splice is not a function
addPoint # highcharts.js:...
How should I use the function "addPoint" in this case?
Or should I use other method to achieve the purpose?

There is something wrong with the function generating your initial data, but addPoint is working fine:
var series;
$(function drawCharts(numberOfPoint) {
// if(typeof chartData == undefined){
// chartData = $(dataStore.getXml());
// }
$("#b").click(function(){
series.addPoint([10,10]);
})
$(document).ready(function () {
Highcharts.setOptions({
global: {
useUTC: false
}
});
$('#container').highcharts({
chart: {
type: 'line',
animation: Highcharts.svg, // don't animate in old IE
marginRight: 10,
events: {
load: function () {
series = this.series[0];
// window.myGlobal1 = this.series[0].data[this.series[0].data.length - 1].y;
// console.log(window.myGlobal1 + " " + this.series[0].data[this.series[0].data.length - 1].y);
},
}

I am not sure what you are trying to do in your series.data function but removing all that code and defining your chart in your click event so it knows what series is does add the point [3,3].
Series declaration now:
series: [{
name: 'Random data',
data: []
}]
And the click function (no moved after the chart code):
$("#b").click(function() {
var chart = $('#container').highcharts();
chart.series[0].addPoint([3, 3]);
})

howto handle objects asp.net javascript highcharts

I'm trying to create a chart with values from my database.
On the server side I throw the values in a list and pass the list to the client.
But somehow the chart just won't display anything at all.
Here's my javascript code:
$(document).ready(function () {
$("#but").click(function (e) {
getData();
});
});
function CreateTempChart(options) {
var chart = new Highcharts.Chart({
chart: {
renderTo: 'chart',
type: 'line',
marginRight: 25,
marginBottom: 25,
zoomType: 'xy'
},
title: {
text: 'Temperature',
x: -20 //center
},
subtitle: {
text: '',
x: -20
},
xAxis: {
type: 'datetime',
categories: []
},
yAxis: {
title: {
text: 'in °C'
},
plotLines: [{
value: 0,
width: 1,
color: '#808080'
}]
},
tooltip: {
formatter: function () {
return '<b>' + this.options.name + '</b><br/>' +
this.x + ': ' + this.y;
}
},
legend: {
layout: 'horizontal',
align: 'center',
verticalAlign: 'top',
x: -50,
y: 40,
borderWidth: 0
},
series:[]
});
chart.addSeries(options);
};
function getData() {
$.ajax({
url: "BasicLine",
dataType: 'json',
type: "POST",
contentType: 'application/json; charset=utf-8',
cache: false,
success: function(result) {
var yo = JSON.parse(result);
var arr = [];
$.map(yo, function (item) {
var t = item.Time.replace("\/Date(", "").replace(")\/", "");
var obj = {
name: "Temperature",
data: item.Value,
categories: t
};
arr.push(obj);
});
var jsonArray = JSON.stringify(arr);
console.log(jsonArray);
CreateTempChart(jsonArray);
},
error: function () {
alert("oh no");
}
});
}
The log looks like this
[{"name":"Temperature","data":10.7,"categories":"1430408770000"},{"name":"Temperature","data":10.8,"categories":"1430408990000"},....]
Any ideas? I'm not quite familiar with js.

How to do a data overlap independently column in Highcharts

I would like to have something similar to the image below, but the columns representing the classes all stack together now. How do I separate them and allow them to load dynamically as well?
Also I need a legend that says green is band 1, yellow is band 2, orange is band 3 and red is band 4, how do i do that as well? My code is in the JS Fiddle page. I am not allowed to use jQuery, need to use pure JavaScript.
var options = {
chart: {
renderTo : 'container',
type: 'column'
},
title: {
text: 'Topic & Subtopic Mastery'
},
subtitle: {
text: 'Average Level-Stream Mastery vs Average Class Mastery'
},
xAxis: {
categories: topics
},
yAxis: {
min: 0,
max: 100,
title: {
text: 'Mastery'
}
},
legend: {
layout: 'vertical',
backgroundColor: '#FFFFFF',
align: 'left',
verticalAlign: 'top',
x: 100,
y: 70,
floating: true,
shadow: true
},
tooltip: {
shared: true,
valueSuffix: ' %'
},
plotOptions: {
column: {
grouping: false,
shadow: false
}
},
series: resultsData
};

I came up with a solution you are looking for with specifying x and y axis data for level and giving appropriate width to the point.
$(function() {
var chart;
$(document).ready(function() {
var i = 0;
Highcharts.getOptions().colors = Highcharts.map(Highcharts.getOptions().colors, function(color) {
if (i == 0) {
i++;
return Highcharts.Color(color)
.setOpacity(1)
.get('rgba');
} else {
i++;
return Highcharts.Color(color)
.setOpacity(0.5)
.get('rgba');
}
});
var colors = Highcharts.getOptions().colors;
chart = new Highcharts.Chart({
chart: {
renderTo: 'container',
type: 'column',
plotBackgroundColor: null,
plotBorderWidth: null,
plotShadow: false,
borderColor: null
},
title: {
text: 'Mailboxes over Quota'
},
subtitle: {
text: 'Mailbox Size in MB'
},
exporting: {
enabled: false
},
credits: {
enabled: false
},
xAxis: {
categories: ["Overall Topic", "Topic 1", "Topic 2"],
title: {
text: null
}
},
yAxis: {
min: 0,
title: {
text: 'Total',
align: 'high'
},
allowDecimals: false,
},
tooltip: {
formatter: function() {
return '' +
this.series.name + ': ' + Highcharts.numberFormat(this.y, 0, '.', ',');
}
},
legend: {
enabled: true
},
credits: {
enabled: false
},
series: [{
name: 'Level',
color: colors[0],
data: [{
y: 86,
x: 0.25
}, {
y: 80,
x: 1.25
}, {
y: 95,
x: 2.25
}],
pointWidth: 80
}, {
name: '4A',
data: [90, 88, 97]
}, {
name: '4B',
data: [95, 78, 92]
}, {
name: '4C',
data: [80, 69, 84]
}]
});
});
});
To show in label inside your column you can use below code.
plotOptions: {
column: {
dataLabels: {
enabled: true,
formatter: function() {
return this.series.name;
},
y: 25,
}
}
}
You can see it in action at this JSFIddle

Cannot get data to display on chart

I am receiving data correctly in my console from the mtgox api. However, I cannot get the data to display on my chart. I'm using highcharts. Any help is appreciated. My code is posted below. Thanks.
Javascript code:
$(document).ready(function() {
$.ajax({
url: "/chart/ajax_get_chart", // the URL of the controller action method
dataType: "json",
type: "GET",
success: function(result) {
var result = JSON.parse(result);
var date = new Array();
var price = new Array();
for (var i = 0; i < result.length; i++) {
date.push(result[i]['date']);
price.push(result[i]['price']);
}
$(function () {
console.log(date);
$('#container').highcharts({
chart: {
type: 'line',
marginRight: 130,
marginBottom: 25
},
title: {
text: 'Bitcoin Price',
x: -20 //center
},
subtitle: {
text: 'Source: MtGox.com',
x: -20
},
xAxis: {
categories: 'datetime'
},
yAxis: {
title: {
text: 'Price'
},
plotLines: [{
value: 'Price',
width: 1,
color: '#808080'
}]
},
tooltip: {
valueSuffix: '°C'
},
legend: {
layout: 'vertical',
align: 'right',
verticalAlign: 'top',
x: -10,
y: 100,
borderWidth: 0
},
series: [{
name: 'Bitcoin',
data: price
}]
});
});
}
});
});
Model:
public function ajax_get_chart() {
$quotes = $this->rest->get('api/1/BTCUSD/trades/fetch');
$series_data = array();
$results = $quotes->return;
foreach ($results as $quote)
{
$series_tmp = array(
'date' => $quote->date,
'price' => $quote->price
);
$series_data[] = $series_tmp;
}
return json_encode($series_data);
}
}

Try changing this:
$('#container').highcharts({
chart: {
type: 'line',
marginRight: 130,
marginBottom: 25
},
to this:
var chart = new Highcharts.Chart({
chart: {
renderTo: 'container'
type: 'line',
marginRight: 130,
marginBottom: 25
},
