Highcharts Gauge: Adding Icons

I'm trying to add icons in dataLabels, I successfully added some HTML like this return '<span style="color:#89891C">Partially rejected: ' + partial + '</span><br/>' +'<span style="color:#933">Rejected: ' + rejected + '</span>';, but now I want to add icons instead, I'm using **Ionicons*. Here's the code:
var chart=Highcharts.chart(id, {
chart: {
type: 'gauge',
alignTicks: false,
plotBackgroundColor: null,
plotBackgroundImage: null,
plotBorderWidth: 0,
plotShadow: false,
backgroundColor:'rgba(255, 255, 255, 0.0)'
},
exporting: { enabled: false },
title: {
text: ''
},
pane: {
startAngle: -150,
endAngle: 150,
background: {
from: 0,
to: partial+rejected,
backgroundColor: '#f55',
innerRadius: '85%',
outerRadius: '50%',
shape: 'arc',
},
},
yAxis: [{
lineWidth: 0,
min: 0,
max: parseInt(val),
tickInterval: 1,
tickPosition: 'outside',
minorTickColor: '#FF0000',
tickColor: '#FF0000',
tickWidth: 2,
tickLength: 10,
minorTickPosition: 'outside',
tickLength: 15,
minorTickLength: 5,
title:{text:'Total: '+val,style:{ color:"#333" }},
labels: {
distance: 25,
},
offset: 5,
endOnTick: false,
plotOptions: {
solidgauge: {
dataLabels: {
y: 5,
borderWidth: 0,
useHTML: true
}
}
},
plotBands: [{
from: 0,
to: delivered,
color: '#21A121',
thickness: '15%',
id: 'plot-band-1'
}]
}],
series: [{
name: 'Managed',
data: [{
id: 'deliver',
y: parseInt(total),
dial: {
backgroundColor:'#D9972E',
radius: '100%',
baseWidth: 10,
baseLength: '5%',
baseWidth: 15,
rearLength: '0%',
}
}],
dataLabels: {
formatter: function () {
var total = this.y;
return '<i class="ion-information-circled" title="RP: '+partial+'" style="color:#EEF007"></i><i class="ion-information-circled" title="RT: '+rejected+'" style="color:#F00707"></i>';
},
backgroundColor: {
linearGradient: {
x1: 10,
y1: 10,
x2: 10,
y2: 11
},
stops: [
[0, '#DDD'],
[1, '#FFF']
]
}
},
tooltip: {
valueSuffix: ' '
}
}]
});
The part I'm trying to get right is at dataLabels, if there's any information you may need to understand what I'm trying to achieve, just ask me, thanks in advance

Simply, get Ionicons CSS file (https://code.ionicframework.com/ionicons/2.0.1/css/ionicons.min.css) and return adequate icon in dataLabels.formatter function. You need to remember that the property useHTML must be set to true.
API Reference:

Is this what you are looking for? JSFiddle
I simply changed the max and min fields in y-axis and changed the javascript function to accommodate the new intervals.
EDIT: I didn't understand the question before, but according to your comment this should work. JSFiddle
EDIT2: Only now I saw you edited the question. Updated the link in EDIT to contain values from -20 to 0 (Before it was from 0 to 20).

Highcharts speedometer gauge change label

I want to implement speedometer to display internet bandwidth speed but I want to change its number sequence. I have search a lot but couldn't find anything.
Please find below code snippet for the highchart gauge. I want to change the label (number). In below example number sequence is 0,10,20,30,...,100.
But my requirement is number sequence should be 0,1,5,10,20,30,40,50,60,70,80,90,100
Check following image of gauge:
Highchart image
But my requirement is number sequence should be 0,1,5,10,20,30,40,50,60,70,80,90,100
Is there any way to change the numbers ?

You can specify specific tick-positions using yAxis.tickPositions (API).
In your case:
yAxis: {
tickPositions: [0,1,5,10,20,30,40,50,60,70,80,90,100]
}
In your example you have yAxis.labels.step set to 2, which needs to be removed so that you don't skip over any labels for your defined tickPositions (unless you want to that is).
See this JSFiddle demonstration of your suggested labels.

Highcharts - Gauge chart data label not positioning correctly

I'm building a vertical gauge and am having problems applying a custom image in place of the default marker.
Although the image renders, it's placement is off. I can't seem to get it to point exactly where the marker is positioned and I'm not sure if applying a static offset value to the 'y' attribute is the right approach.
Here's a fiddle.
var chart = new Highcharts.Chart({
chart: {
renderTo: 'container',
type: 'column',
marginBottom: 25,
marginTop: 70,
marginLeft: 65,
marginRight: 10,
},
xAxis: {
categories: ['One'],
lineColor: 'white',
labels: {
enabled: false
},
tickLength: 0,
min: 0,
max: 2
},
plotOptions: {
column: {
stacking: 'normal',
animation: false,
borderWidth: 0,
}
},
yAxis: {
min: 0,
max: 9026,
tickInterval: 9026,
tickLength: 0,
tickWidth: 0,
tickColor: '#C0C0C0',
gridLineColor: '#C0C0C0',
gridLineWidth: 0,
minorTickInterval: 25,
minorTickWidth: 0,
minorTickLength: 0,
minorGridLineWidth: 0,
title: null,
labels: {
formatter: function () {
if (this.isFirst || this.isLast) {
return this.value;
}
},
x: 0
},
},
legend: {
enabled: false
},

{
data: [4513],
color: {
linearGradient: { x1: 0, x2: 0, y1: 0, y2: 1 },

[0, 'red'],
[1, 'orange']
]
}
},
{
data: [4513],
color: {
linearGradient: { x1: 0, x2: 0, y1: 0, y2: 1 },
stops: [
[0, 'orange'],
[1, 'green']
]
}
},
{
type: 'scatter',
data: [3120],
marker: {
enabled: true,
symbol: 'circle'
},
dataLabels: {
useHTML: true,
formatter: function () {
return '<img width="40px" height="40px" src="http://icongal.com/gallery/image/57585/small_arrow_black_monotone_left.png" />'
},
enabled: true,
align: 'right',
x: -3,
y: 2,
overflow: "justify"
}
}
]
});
<script src="https://code.highcharts.com/highcharts.js"></script>
<div id="container" style="width: 178px; height: 242px;"></div>
Would appreciate any help, thanks!

You should adjust the image position via x, y properties.
x: 0,
y: 30,
example: https://jsfiddle.net/ptezqnbf/1/
or even better, use renderer.image and control the position directly.
function renderImage() {
var chart = this,
point = chart.get('point'),
imgWidth = 40,
imgHeight = 40;
if (!chart.dataLabelImg) {
chart.dataLabelImg = this.renderer.image('http://icongal.com/gallery/image/57585/small_arrow_black_monotone_left.png', -1000, -1000, imgWidth, imgHeight).add(point.series.dataLabelsGroup);
}
chart.dataLabelImg.attr({
x: point.graphic.x + (imgWidth - 15) / 2,
y: point.graphic.y - (imgHeight - 10) / 2
});
example: https://jsfiddle.net/tpp1gdau/1/

How do I pass jquery result to highchart

Absolute novice here at JavaScript so please forgive any bad coding.
I have been working on a project using Highchart and wish to read the value of a file (actually read the file into an array and grab a specific value - I will use other values for other graphs).
With the help of others here I can now display the value of the array into HTML however I cannot pass this into the Highchart.
My prototype page (so you can see the output) can be found at
http://maccas.chickenkiller.com/1.html
The code is

Does anyone have an idea how to get the var phvalue to display in Highcharts?
Thanks in advance.

Since ajax is asynchronous, you can draw the graph once the request is complete
jQuery(function($){ // encapsulate jQuery
$.ajax(
{
url:'livedata.txt',
async:false,
success: function(data){
livedata = data.split(',');
highcharts(livedata[3])
}
});
function highcharts (phvalue) {
$('#realtimeph').highcharts({
chart: {
type: 'gauge',
plotBackgroundColor: null,
plotBackgroundImage: null,
plotBorderWidth: 0,
plotShadow: false
},
title: {
text: 'live pH'
},
pane: {
startAngle: -150,
endAngle: 150,
background: [{
backgroundColor: {
linearGradient: { x1: 0, y1: 0, x2: 0, y2: 1 },
stops: [
[0, '#FFF'],
[1, '#333']
]
},
borderWidth: 0,
outerRadius: '109%'
}, {
backgroundColor: {
linearGradient: { x1: 0, y1: 0, x2: 0, y2: 1 },
stops: [
[0, '#333'],
[1, '#FFF']
]
},
borderWidth: 1,
outerRadius: '107%'
}, {

}, {
backgroundColor: '#DDD',
borderWidth: 0,
outerRadius: '105%',
innerRadius: '103%'
}]
},
// the value axis

min: 8,
max: 9,
minorTickInterval: 'auto',
minorTickWidth: 1,
minorTickLength: 10,
minorTickPosition: 'inside',
minorTickColor: '#666',
tickPixelInterval: 30,
tickWidth: 2,
tickPosition: 'inside',
tickLength: 10,

This was surprisingly complicated. You want:
$('#container').highcharts().series[0].points[0].update(x)
where x is the number you want to update with
