Two different thresholds in HighCharts 3.0 - highcharts

With HighCharts 3.0, it is now possible to indicate to colors above and below one threshold. Like this example :
http://jsfiddle.net/highcharts/YWVHx/
Following code :
$(function () {
$.getJSON('http://www.highcharts.com/samples/data/jsonp.php?filename=range.json&callback=?', function(data) {
$('#container').highcharts({
chart: {
type: 'arearange'
},
title: {
text: 'Temperature variation by day'
},
xAxis: {
type: 'datetime'
},
yAxis: {
title: {
text: null
}
},
tooltip: {
crosshairs: true,
shared: true,
valueSuffix: '°C'
},
legend: {
enabled: false
},
series: [{
name: 'Temperatures',
data: data,
color: '#FF0000',
negativeColor: '#0088FF'
}]
});
});
});
Is it possible to have another threshold with a third color, like this for example :
Thanks in advance for your help.

It actually is possible if you don't mind plotting the data twice.
$('#container').highcharts({
chart: {
type: 'arearange'
},
title: {
text: 'Temperature variation by day'
},
xAxis: {
type: 'datetime'
},
yAxis: {
title: {
text: null
}
},
tooltip: {
crosshairs: true,
shared: true,
valueSuffix: '°C'
},
legend: {
enabled: false
},
series: [{
name: 'Temperatures',
threshold : 0,
data: data,
color: 'orange',
negativeColor: 'blue'
},
{
name: 'Temperatures',
threshold : 10,
data: data,
color: 'red',
negativeColor: 'transparent'
}]
});
});

A feature to solve this without "hacks" was added in Highcharts 4.1.0 (February 2015), called zones (API). The given problem can be solved like this, using zones:
plotOptions: {
series: {
zones: [{
value: 0, // Values up to 0 (not including) ...
color: 'blue' // ... have the color blue
},{
value: 10, // Values up to 10 (not including) ...
color: 'orange' // ... have the color orange
},{
color: 'red' // Values from 10 (including) and up have the color red
}]
}
}
See this JSFiddle demonstration of how it looks.

Unfortunately this option is not possible, but you can request your suggestion in http://highcharts.uservoice.com and vote for it.

By the way, I can try use a plotLine, like this:
yAxis: {
title: {
text: 'My Chart'
},
plotLines: [{
id: 'limit-min',
dashStyle: 'ShortDash',
width: 2,
value: 80,
zIndex: 0,
label : {
text : '80% limit'
}
}, {
id: 'limit-max',
color: '#008000',
dashStyle: 'ShortDash',
width: 2,
value: 90,
zIndex: 0,
label : {
text : '90% limit'
}
}]
},

Highchart : drill down tree map conditional coloring with dynamic data

I am not able to set the color in tree map based on a value. value is coming dynamically from api response. Here is how I am trying to achieve same but id is not working. It is a drilldown tree map.if anyone can help me. I want to set the colors as per the colorvalue.
function treeMap(containerID, jsonData, titleText, subTitleText, type, colorValue) {
Highcharts.AST.allowedAttributes.push('onmousedown')
treeChart = Highcharts.chart(containerID, {
colorAxis: {
minColor: Highcharts.getOptions().colors[9],
maxColor: '#FFFFFF',
},
plotOptions: {
series: {
turboThreshold: 10000
}
},
series: [{
type: "treemap",
allowDrillToNode: true,
layoutAlgorithm: 'squarified',
dataLabels: {
enabled: false
},
levelIsConstant: false,
levels: [{
level: 1,
dataLabels: {
enabled: true
},
borderWidth: 3
}],
name: titleText,
data: jsonData[0].concat(jsonData[1]),
colorKey:colorValue
}],
tooltip: {
useHTML: true,
style: {
pointerEvents: 'auto'
},
stickOnContact: true,
pointFormatter: function() {
return chartToolTip(this, type);
}
},
title: {
text: titleText
},
subtitle: {
text: subTitleText
}
});
}
As API says, series.colorKey is a string that determinates what data value should be used to calculate point color. Whereas colorValue should be passed with data. I hope the following, simplified example will clarify it:
Example code:
let colorValue = [1, 5, 10];
Highcharts.chart('container', {
colorAxis: {
minColor: '#FFF000',
maxColor: '#0000FF'
},
series: [{
type: 'treemap',
colorKey: 'colorValue',
data: [{
value: 4,
colorValue: colorValue[0]
}, {
value: 3,
colorValue: colorValue[1]
}, {
value: 2,
colorValue: colorValue[1]
}, {
value: 1,
colorValue: colorValue[2]
}]
}]
});

highcharts x-axis not showing with series of just one value

I use highcharts for a chart. I made series with "linkedTo" because I need to group the columns by region and generate a legend displaying these regions. Until then, the result is the desired one. But I can not display the name of my categories on the X axis. Under each column there should be "A", "B", ... As in the picture. See the jsfiddle for the code. Thank you for your help.
http://jsfiddle.net/yucca/hpkLy6t0/24/
// Create the chart
Highcharts.chart('container', {
chart: {
type: 'column'
},

type: 'category',

return this.userOptions.id
}
},

You need to make a slight alteration to your series in order for this to work.
series: [{
data: [{
id:'China',
color: '#004f9e',
y: 1100
},{
id:'International',
color: '#e73357',
y: 10
},{
linkedTo: 'International',
color: '#e73357',
y: 1000
},{
linkedTo: 'China',
color: '#004f9e',
y: 686
}],
}]
What I did is the following:
I changed the data[] so it holds an array of your values.
I changed the values stored as data: [686] to y: 686

PHP mySQL Highcharts Json Multiselect

I am trying to make a scatter plot with two serie names (subcategory).
This example from highcharts is my starting point.
In this example, you only have two categories, namely female and male. I would like to see the name of the female/male in the tooltip. Not in the legend!
In my example jsfiddle I added four names in the data and tooltip
I understand that this is not the correct way, but I would like to clarify what I want to achieve. Does anyone know how to process this correctly, so that there are still two categories in the legend (female/male), but in the tooltip also the name of the female/male.
Thank you so much already!

data: [{name: 'James',[174.0, 65.6], {name: 'Peet',[175.3, 71.8]]
}]
});
You have a fair number of errors with brackets and curly brackets, where there are too many or few brackets. Too many for me to point them all out, but mainly around the section area.
However, you need to define the scatter plot coordinates as x, and y when you define a name for the series, like this:
series: [{
name: 'Female',
data: [{
name: 'Anna'
x: 161.2,
y: 51.6
},
...
]
}
...
]
Also, to show the name of the datapoint (i.e. the person), you can use the following tooltip formatter:
tooltip: {
headerFormat: '<b>{series.name}</b><br>',
pointFormat: 'Name: {point.name}, {point.x} cm, {point.y} kg'
}

Highcharts stock chart - Technical Indicators - Stock price is missing in the tooltip when selecting the 'All' range

When selecting the "All"-range in a HighStock chart with technical indicators then
the stock price (AAPL stock price) is not listed (most of the time, sometimes it appears) in the tooltip.
Open the sample chart here: http://jsfiddle.net/laff/SRfW6/
Hover over the chart and notice that the stock price is listed in the tooltip.
Click on the 'All' range selection.
Hover over the chart and notice that the stock price is no longer listed most of the time in the tooltip.
Has anybody an idea what the problem might be?
This the code from the example:
$.getJSON('http://www.highcharts.com/samples/data/jsonp.php?filename=aapl-c.json&callback=?', function(data) {
$(function() {
$('#container').highcharts('StockChart', {
title : {
text : 'MACD of AAPL stock price'
},
subtitle: {
text: 'From may 15, 2006 to May 10, 2013'
},
yAxis: [{
title: {
text: 'Price'
},
height: 200,
plotLines: [{
value: 0,
width: 1,
color: '#808080'
}]
}, {
title: {
text: 'MACD'
},
top: 300,
height: 100,
offset: 0,
lineWidth: 2
}],
tooltip: {
crosshairs: true,
shared: true
},
rangeSelector : {
selected : 1
},
legend: {
enabled: true,
layout: 'vertical',
align: 'right',
verticalAlign: 'middle',
borderWidth: 0
},
plotOptions: {
series: {
marker: {
enabled: false,
}
}
},
series : [{
name: 'AAPL Stock Price',
type : 'line',
id: 'primary',
data : data
}, {
name : 'MACD',
linkedTo: 'primary',
yAxis: 1,
showInLegend: true,
type: 'trendline',
algorithm: 'MACD'
}, {
name : 'Signal line',
linkedTo: 'primary',
yAxis: 1,
showInLegend: true,
type: 'trendline',
algorithm: 'signalLine'
}, {
name: 'Histogram',
linkedTo: 'primary',
yAxis: 1,
showInLegend: true,
type: 'histogram'
}]
});
});
});
Just adding this code to plotOptions.series seems to fix it (JSFiddle demonstration):
dataGrouping: { }
It appears that given your original code dataGrouping was somehow null.
I'll be honest. I don't know why. Looks borderline buggy.

Sort series per category

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,
