PHP mySQL Highcharts Json Multiselect - highcharts

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!
Highcharts.chart('container', {
chart: {
type: 'scatter',
zoomType: 'xy'
},
title: {
text: 'Height Versus Weight of 507 Individuals by Gender'
},
subtitle: {
text: 'Source: Heinz 2003'
},
xAxis: {
title: {
enabled: true,
text: 'Height (cm)'
},
startOnTick: true,
endOnTick: true,
showLastLabel: true
},
yAxis: {
title: {
text: 'Weight (kg)'
}
},
legend: {
layout: 'vertical',
align: 'left',
verticalAlign: 'top',
x: 100,
y: 70,
floating: true,
backgroundColor: (Highcharts.theme && Highcharts.theme.legendBackgroundColor) || '#FFFFFF',
borderWidth: 1
},
plotOptions: {
scatter: {
marker: {
radius: 5,
states: {
hover: {
enabled: true,
lineColor: 'rgb(100,100,100)'
}
}
},
states: {
hover: {
marker: {
enabled: false
}
}
},
tooltip: {
headerFormat: '<b>{series.name}</b><br>',
pointFormat: 'name: (), {point.x} cm, {point.y} kg'
}
}
},
series: [{
name: 'Female',
color: 'rgba(223, 83, 83, .5)',
data: [{name: 'Anna', [161.2, 51.6]}, {name: 'Clair',[167.5, 59.0]]
}, {
name: 'Male',
color: 'rgba(119, 152, 191, .5)',
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'
}

Highchart - how to control gap between series

In Highcharts, how do I control the gaps between categories?
I've highlighted the area I am talking about in blue below:
I want to make my highchart chart gaps look like this powerpoint version on the left below. The bars in PowerPoint go all the way to the end of the plot area, but highcharts have this big gap.
https://jsfiddle.net/15u0r64s/
Highcharts.chart('container', {
chart: {
type: 'bar'
},
title: {
text: 'Historic World Population by Region'
},
subtitle: {
text: 'Source: Wikipedia.org'
},
xAxis: {
categories: ['Total', 'Male', 'Female', 'Other'],
title: {
text: null
}
},
yAxis: {
min: 0,
title: {
text: 'Population (millions)',
align: 'high'
},
labels: {
overflow: 'justify'
}
},
tooltip: {
valueSuffix: ' millions'
},
plotOptions: {
bar: {
dataLabels: {
enabled: true
}
}
},
legend: {
layout: 'vertical',
align: 'right',
verticalAlign: 'top',
x: -40,
y: 80,
floating: true,
borderWidth: 1,
backgroundColor:
Highcharts.defaultOptions.legend.backgroundColor || '#FFFFFF',
shadow: true
},
credits: {
enabled: false
},
series: [{
name: 'Total',
data: [10, 20, 31, '']
}, {
name: 'Male',
data: [10, 20, 60, 2]
}, {
name: 'Female',
data: [10, 20, 61, '']
}, {
name: 'Other',
data: [10, 20, 65, 4]
}]
});
You need to edit groupPadding and pointPadding properties:
plotOptions: {
bar: {
groupPadding: 0.05,
pointPadding: 0
}
}

Highcharts Maps labels don't all show

Playing with the Highcharts Map samples and wanted to see how multiple series worked with maps. Here is the US population density map with another series showing the state capitals:
$.getJSON('https://cdn.rawgit.com/highcharts/highcharts/057b672172ccc6c08fe7dbb27fc17ebca3f5b770/samples/data/us-capitals.json', function (dcap) {
$.getJSON('https://cdn.rawgit.com/highcharts/highcharts/057b672172ccc6c08fe7dbb27fc17ebca3f5b770/samples/data/us-population-density.json', function (data) {
// Make codes uppercase to match the map data
$.each(data, function () {
this.code = this.code.toUpperCase();
});
if (_dochartwhenready === true) {
if (_domap === true) {
var mapobject = {
chart: {
map: 'countries/us/us-all',
borderWidth: 1,
renderTo: 'container'
},
title: {
text: 'US population density (/km²)'
},
exporting: {
sourceWidth: 600,
sourceHeight: 500
},
legend: {
layout: 'horizontal',
borderWidth: 0,
backgroundColor: 'rgba(255,255,255,0.85)',
floating: true,
verticalAlign: 'top',
y: 25
},
mapNavigation: {
enabled: true
},
colorAxis: {
min: 1,
type: 'logarithmic',
minColor: '#EEEEFF',
maxColor: '#000022',
stops: [
[0, '#EFEFFF'],
[0.67, '#4444FF'],
[1, '#000022']
]
},
series: [{
animation: {
duration: 1000
},
data: data,
joinBy: ['postal-code', 'code'],
dataLabels: {
enabled: true,
color: '#FFFFFF',
format: '{point.code}'
},
name: 'Population density',
tooltip: {
pointFormat: '{point.code}: {point.value}/km²'
}
},
{
animation: {
duration: 3000
},
type: 'mappoint',
name: 'Cities',
color: Highcharts.getOptions().colors[1],
data: dcap,
joinBy: ['lat', 'lat', 'lon', 'lon'],
dataLabels: {
enabled:true,
color: '#ccccc',
format: '{point.capital}'
},
tooltip: {
pointFormat: '{point.capital}: {point.population}'
}
}]
};
_map = new Highcharts.Map(mapobject);
}
This works -- partly:
The tool tips work exactly as expected. However, only a few state capital names show up on the map. How come?
The source of the problem are overlapping data labels. This code forces Highcharts to show all of them:
plotOptions: {
series: {
dataLabels: {
allowOverlap: true
}
}
},
Live demo: https://jsfiddle.net/BlackLabel/vtwv061b/
API reference: https://api.highcharts.com/highmaps/plotOptions.series.dataLabels.allowOverlap
This is simply due the zoom level, aparently.
Also, I would not recomend using joinBy on lat and long since the may vary in really small decimals.
Here's a fiddle with a working example: https://jsfiddle.net/3ttmyxmo/
If you zoom in you will see the capital names popping over.
I used joinBy on postal-code and abrev instead of lat long:
{
animation: {
duration: 3000
},
type: 'mappoint',
name: 'Cities',
color: Highcharts.getOptions().colors[1],
data: capitals,
joinBy: ['postal-code', 'abrev'],
dataLabels: {
enabled:true,
color: '#ccccc',
format: '{point.capital}'
},
tooltip: {
pointFormat: '{point.capital}: {point.population}'
}
}

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'
},
title: {
text: 'TEST'
},
subtitle: {
text: 'TEST'
},
xAxis: {
type: 'category',
categories: ['A', 'B', 'C', 'D']
},
legend: {
enabled: true,
labelFormatter: function() {
return this.userOptions.id
}
},
plotOptions: {
series: {
borderWidth: 0,
dataLabels: {
enabled: false,
}
}
},
tooltip: {
headerFormat: '<span style="font-size:11px">{series.name}</span><br>',
pointFormat: '<span style="color:{point.color}">{point.name}</span>: <b>{point.y:.2f}%</b> of total<br/>'
},
series: [
{
id:'China',
color: '#004f9e',
data: [1100]
},
{
id:'International',
color: '#e73357',
data: [10]
},
{
linkedTo: 'International',
color: '#e73357',
data: [1000]
},
{
linkedTo: 'China',
color: '#004f9e',
data: [686]
}
]
});
graph
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
Here you can find a working JSFiddle

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.

Two different thresholds in HighCharts 3.0

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'
}]
});
});
http://jsfiddle.net/YWVHx/97/
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'
}
}]
},
