I wanted to know if it's possible to use an async drill down on treemap?
I have 7000 items that need to be drawn and it stuck while the treemap is creating.
So I think to create treemap by lazy loading. I didn't find any example of treemap with huge data (while the items are below 1000 it's not a problem like in the example of the large treemap).
I will appreciate any help.
Yes, it can be done exactly the same for any type of series.
Example for treemap:
Highcharts.chart('container', {
chart: {
events: {
drilldown: function(e) {
this.addSeriesAsDrilldown(e.point, {
type: "treemap",
layoutAlgorithm: 'squarified',
data: [{
name: 'A1',
value: 11,
drilldown: true
}, {
name: 'A2',
value: 44
}]
});
}
}
},
series: [{
type: "treemap",
layoutAlgorithm: 'squarified',
data: [{
name: 'A',
value: 6,
drilldown: true
}, {
name: 'B',
value: 2
}]
}]
});

I want to create a stock chart that can change its data based on a select box of the stock symbol. The problem is when I update the main series data, the linked series (overlays indicator) is not updating.
Highcharts.stockChart('container', {
...
series: [{
type: 'candlestick',
id: 'main-series',
name: 'AAPL',
data: data
}, {
type: 'column',
id: 'volume',
name: 'Volume',
data: volume,
yAxis: 1
}, {
type: 'pc',
id: 'overlay',
linkedTo: 'main-series',
yAxis: 0
}, {
type: 'macd',
id: 'oscillator',
linkedTo: 'main-series',
yAxis: 2
}]
...
}, function (chart) {
changeSymbol(chart);
document.getElementById('symbols').addEventListener('change', function(e) {
changeSymbol(chart);
});
});

Change the symbol select between "Apple" and "Half Apple" to see the error
I have a game with 3 difficulties and I show their averages in a first graph. Now I want to use drilldown to show a spread of the scores for each difficulty in a histogram. I managed to get this working but I have two problems. First of all I use update to change the setting for the drilldown graphs, but then these settings also change for the first graph and thus I was wondering what the better way would be to do this.
My other problem is that in my histogram the first and last column are cut in half and only half is shown, but I cant seem to find a way to solve this. I tried min- and maxPadding but this did not work.

title:{text: "Nr of skipped patients"},
tickmarkPlacement: 'on',
},
yAxis:{title:{text: "Nr of players"}},
plotOptions:{series:{pointPlacement: 'on'}},
});
if (!e.seriesOptions) {
var chart = this,
drilldowns = {
'Histogram: Easy': {
name: 'Easy',
type: 'histogram',
baseSeries: 'avgSkippedEasy'
},
'Easy': {
id: 'avgSkippedEasy',
visible: false,
type: 'column',

},
series = [drilldowns['Histogram: ' + e.point.name], drilldowns[e.point.name]];
chart.addSingleSeriesAsDrilldown(e.point, series[0]);
chart.addSingleSeriesAsDrilldown(e.point, series[1]);
chart.applyDrilldown();
}

name: 'Averages per difficulty',
colorByPoint: true,

data: [{

y: 5,
drilldown: true

y: 4,
drilldown: true

drilldown: {

You should define your initial options as a variable and attach them again in the drillup callback due to you did a chart update with changed the initial options.

I want to create a drill down chart but when a certain bar or label is click the next chart to display will be load/get data from Database first. It means that 2nd level drill down is not yet preloaded. I don't know how to do it or the right functions to search.
Thank you.
In drilldown event you can get data and use addSeriesAsDrilldown method:
Highcharts.chart('container', {
chart: {
type: 'column',
events: {
drilldown: function(e) {
if (!e.seriesOptions) {
var chart = this,
source = {
Animals: 'https://api.myjson.com/bins/100f5h',
Fruits: 'https://api.myjson.com/bins/csik5',
Cars: 'https://api.myjson.com/bins/sxd1x'
};
chart.showLoading('Waiting for data...');
$.get(source[e.point.name], function(data) {
chart.hideLoading();
chart.addSeriesAsDrilldown(e.point, data[e.point.name]);
});
}
}
}
},
...
series: [{
...,
data: [{
name: 'Animals',
y: 5,
drilldown: true
}, {
name: 'Fruits',
y: 2,
drilldown: true
}, {
name: 'Cars',
y: 4,
drilldown: true
}]
}],
drilldown: {
series: []
}
});

I'm trying to draw two lines in HighStocks using JavaScript with their example candlestick with intraday code. For some reason I can't get it to work
I am trying to just generate two extra lines at the end of my candlestick data, here is what i have (testing with just one line but it wont work). You can see the line im trying to put in is called test
$(function () {
$.getJSON('https://www.highcharts.com/samples/data/jsonp.php?filename=new-intraday.json&callback=?', function (data) {
// create the chart
$('#container').highcharts('StockChart', {
title: {
text: 'AAPL stock price by minute'
},
rangeSelector: {
buttons: [{
type: 'hour',
count: 1,
text: '1h'
}, {
type: 'day',
count: 1,
text: '1D'
}, {
type: 'all',
count: 1,
text: 'All'
}],
selected: 1,
inputEnabled: false
},
series: [{
name: 'AAPL',
type: 'candlestick',
data: data,
tooltip: {
valueDecimals: 2
}
}]
series: [{
name: 'test',
type: 'line',
data: [200.0, 201.0, 300.0, 400.0],
}]
});
});
});
First of all, you should not add two series arrays in your chart options object. You should use one series array and inside this array add new series object:
series: [{
name: 'AAPL',
type: 'candlestick',
data: data,
tooltip: {
valueDecimals: 2
}
}, {
name: 'test',
type: 'line',
data: [200.0, 201.0, 300.0, 400.0],
}]
The problem with this case is that you didn't give any x values to your line points, so it will start from 1970 year right now.
You need to add x values so line will start just where you want.

I have a chart that looks like this:
http://jsfiddle.net/rtGFm/37/
I would like to have a "sort" button that sorts high to low each category, putting the columns in a different order for each category. Is this possible with HighCharts?
var chart;
$(document).ready(function() {
chart = new Highcharts.Chart({
chart: {
renderTo: 'container',
type: 'column'
},
title: {
text: ''
},
subtitle: {
text: ''
},
xAxis: {
categories: [
'foreclosures',
'nuisances',
'distance from city center'
]
},
yAxis: {
min: 0,
title: {
text: ''
}
},
tooltip: {
formatter: function() {
return ''+
this.x +': '+ this.y +' mm';
}
},
plotOptions: {
column: {
pointPadding: 0.2,
borderWidth: 0
}
},
series: [{
name: 'Alger Heights',
data: [49.9, 71.5, 50]
}, {
name: 'Shawmut Hills',
data: [83.6, 78.8, 67]
}, {
name: 'Baxter',
data: [48.9, 38.8, 100]
}, {
name: 'Midtown',
data: [42.4, 33.2, 80]
}, {
type: 'scatter',
data: [55,60,70],
marker: {
symbol: 'square',
lineColor: '#FFFFFF',
lineWidth: 1,
radius: 8
},
name: 'Average'
}]
});
});
I had the same problem :) highcharts still does not provide any solution for this problem, but it is flexibel enough so that you can sort anyway - just by javascript.
Put your data in a separate value:
var dataMain = [{name:"test1",data:5}, {name:"test1",data:1},{name:"test1",data:2}]
In series you can just add a function which sorts your data:
series: (function(){
for(var i = 0;i<dataMain.length;i++){
dataMain[i].data = dataMain[i].data.sort(function(a,b){
return a[0] - b[0] ;
})
return dataMain;
}
Hope I got everything wright.
Got it to work, I believe. Trick is to add each column in correct order as a new serie with same type (column), reuse colors and hide legend...
Very hackish, the JS code to sort like 8 categories independently will be ugly but the result looks fine.
Edit: Updated fiddle, I see the spacing between the categories grows with series, doesn't look supernice.
My jsfiddle is here
$(function () {
$('#container').highcharts({
chart: {
inverted: true
},
title: {
text: 'Series sorted in within categories'
},
xAxis: {
categories: ['January']
},
series: [{
type: 'column',
name: 'Stockholm',
data: [{x:0, y:95, color: Highcharts.getOptions().colors[0]}]
}, {
type: 'column',
name: 'Göteborg',
data: [{x:0, y:80, color: Highcharts.getOptions().colors[1]}]
}, {
type: 'column',
name: 'Göteborg',
data: [{x: 1, name: 'February', y: 98, color: Highcharts.getOptions().colors[1] // VGR's color
}],
showInLegend: false,
dataLabels: {
enabled: false
}
}, {
type: 'column',
name: 'Stockholm',
data: [{x: 1, name: 'February', y: 80, color: Highcharts.getOptions().colors[0] // VGR's color
}],
showInLegend: false,
dataLabels: {
enabled: false
}
}]
});
});

I think this can be done,
this may look like a little work around.
since we have a limited number of columns i mean 4 in the given example.
if we have arrays with sorting done with respect to each series then we can handle them.
on button click we can update the chart with new set of data as well as category array.
May be there is no solution from the APi.
According to me this is a possible approach.
Thanks,
