Highcharts Angular gauge - How to remove data label stroke?

I have a standard Angular gauge, and I can't figure out how to remove the silver border (stroke) from the data labels.
Using the following code, taken from http://www.highcharts.com/demo/gauge-speedometer
$(function () {
$('#container').highcharts({
chart: {
type: 'gauge',
plotBackgroundColor: null,
plotBackgroundImage: null,
plotBorderWidth: 0,
plotShadow: false
},
title: {
text: 'Speedometer'
},
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%'
}, {
// default background
}, {
backgroundColor: '#DDD',
borderWidth: 0,
outerRadius: '105%',
innerRadius: '103%'
}]
},
// the value axis
yAxis: {
min: 0,
max: 200,
minorTickInterval: 'auto',
minorTickWidth: 1,
minorTickLength: 10,
minorTickPosition: 'inside',
minorTickColor: '#666',
tickPixelInterval: 30,
tickWidth: 2,
tickPosition: 'inside',
tickLength: 10,
tickColor: '#666',
labels: {
step: 2,
rotation: 'auto'
},
title: {
text: 'km/h'
},
plotBands: [{
from: 0,
to: 120,
color: '#55BF3B' // green
}, {
from: 120,
to: 160,
color: '#DDDF0D' // yellow
}, {
from: 160,
to: 200,
color: '#DF5353' // red
}]
},
series: [{
name: 'Speed',
data: [80],
tooltip: {
valueSuffix: ' km/h'
}
}]
},
// Add some life
function (chart) {
if (!chart.renderer.forExport) {
setInterval(function () {
var point = chart.series[0].points[0],
newVal,
inc = Math.round((Math.random() - 0.5) * 20);
newVal = point.y + inc;
if (newVal < 0 || newVal > 200) {
newVal = point.y - inc;
}
point.update(newVal);
}, 3000);
}
});
});
I understand I can style the text within the data label, for example:
dataLabels: {
format: '<span style="font-size:18px">Consumption: {y} kWh</span>',
x: 0,
y: 50
},
But I can't seem to find a way to remove the stroke. Looking at the source it's written as attributes in the rect-tag.
<rect x="0.5" y="0.5" width="95" height="27" fill="none" stroke="silver" stroke-width="1" rx="3" ry="3"></rect>
Is there a way to remove this stroke using Highcharts? Any help is appreciated!

If you want to remove border from displayed dataLabel, you can use dataLabels.borderWidth parameter from Highcharts API:
http://api.highcharts.com/highcharts/plotOptions.series.dataLabels.borderWidth
plotOptions: {
series: {
dataLabels: {
borderWidth: 0
}
}
},
Here you can see an example how it can work:

Highcharts multiple yaxis plotband collision

I have been trying using angular gauge with multiple y axis. I have used offset axis property to avoid collision between them. However, plotband of the axes getting collided with each other. Is there any property to separate them out or any other workaround?
My try:
$(function () {
$('#container').highcharts({
chart: {
type: 'gauge',
plotBackgroundColor: null,
plotBackgroundImage: null,
plotBorderWidth: 0,
plotShadow: false

text: 'Speedometer'
},
pane: {
startAngle: -90,
endAngle: 90,
background: null
},
// the value axis
yAxis:[
{
min: 0,
max:100,
minorTickInterval: 'auto',
minorTickWidth: 1,
minorTickLength: 10,
minorTickPosition: 'inside',

}
});
$('.highcharts-axis text').click(function(){ alert($(this).text());
});
});

Is there a way to cap Highchart's Gauge at the max

Im looking to have a set min and max (0-200) and to cap the gauge line at the 200. The data could be over 200, but the line on the gauge would still need to cap at 200.
Is there a parameter to do this?
chart: {
type: 'gauge',
plotBackgroundColor: null,
plotBackgroundImage: null,
plotBorderWidth: 0,
plotShadow: false
},
title: {
text: 'Speedometer'
},
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%'
}, {
// default background
}, {
backgroundColor: '#DDD',
borderWidth: 0,
outerRadius: '105%',
innerRadius: '103%'
}]
},
// the value axis
yAxis: {
min: 0,
max: 200,
minorTickInterval: 'auto',
minorTickWidth: 1,
minorTickLength: 10,
minorTickPosition: 'inside',
minorTickColor: '#666',
tickPixelInterval: 30,
tickWidth: 2,
tickPosition: 'inside',
tickLength: 10,
tickColor: '#666',
labels: {
step: 2,
rotation: 'auto'
},
title: {
text: 'km/h'
},
plotBands: [{
from: 0,
to: 120,
color: '#55BF3B' // green
}, {
from: 120,
to: 160,
color: '#DDDF0D' // yellow
}, {
from: 160,
to: 200,
color: '#DF5353' // red
}]
},
series: [{
name: 'Speed',
data: [555],
tooltip: {
valueSuffix: ' km/h'
}
}]

You can use plotOptions.gauge.wrap: false to prevent wrapping around.
The API description:
wrap: Boolean
When this option is true, the dial will wrap around the axes. For instance, in a full-range gauge going from 0 to 360, a value of 400 will point to 40. When wrap is false, the dial stops at 360. Defaults to true.
Example usage (JSFiddle):
plotOptions: {
gauge: {
wrap: false
}
}

Highcharts Gauge - how to read input from file?

I currently just started on JS and needed highcharts for a project, so far so good, but I do have a very newbie question:
I have some task doing a cron job and outputing a value range: 10-90 to a file. How can I load the value into the gauge?
Here is the code I adapted (ranges, look and feel dont matter), i only could make a static value 53.8 :
$(function () {
$('#container').highcharts({
chart: {
type: 'gauge',
plotBackgroundColor: null,
plotBackgroundImage: null,
plotBorderWidth: 0,
plotShadow: false
},
title: {
text: 'Speedometer'
},
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%'
}, {
// default background
}, {
backgroundColor: '#DDD',
borderWidth: 0,
outerRadius: '105%',
innerRadius: '103%'
}]
},
// the value axis
yAxis: {
min: 0,
max: 200,
minorTickInterval: 'auto',
minorTickWidth: 1,
minorTickLength: 10,
minorTickPosition: 'inside',
minorTickColor: '#666',
tickPixelInterval: 30,
tickWidth: 2,
tickPosition: 'inside',
tickLength: 10,
tickColor: '#666',
labels: {
step: 2,
rotation: 'auto'
},
title: {
text: 'km/h'
},
plotBands: [{
from: 0,
to: 120,
color: '#55BF3B' // green
}, {
from: 120,
to: 160,
color: '#DDDF0D' // yellow
}, {
from: 160,
to: 200,
color: '#DF5353' // red
}]
},
series: [{
name: 'Speed',
data: [80],
tooltip: {
valueSuffix: ' km/h'
}
}]
}
);
$('#container').highcharts().series[0].points[0].update(50.8)
});
Here is the jsfiddle link: http://jsfiddle.net/H8uGk/ , can you guys give me a tip how to read the content of a file? (a number in this case)
Is there any way to do it in javascript? It doesn't need to be dynamic , and i was avoiding using php.
Thank you,

The simplest is to just copy/paste it into your js file, which I'm assuming isn't good enough because you want it to be dynamic.
If you need it to be dynamic, you can't do this in javascript, because the javascript runs on the client (ie the web browser), but it needs to read from the server (ie the original machine). So, you have to create an "endpoint" to read the file, check out something simple in php like this:
<?php
// > PHP 5
$file = file_get_contents('./gauge_data.txt', FILE_USE_INCLUDE_PATH);
?>

Live data will not load in HighCharts gauge

I am trying to make a Gauge chart.
The chart is displaying 80 but live data is not working.
I use the following code:
$(function () {
var chart = new Highcharts.Chart({
chart: {
renderTo: 'container',
type: 'gauge',
plotBackgroundColor: null,
plotBackgroundImage: null,
plotBorderWidth: 0,
plotShadow: false
},
title: {
text: 'Speedometer'
},
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%'
}, {
// default background
}, {
backgroundColor: '#DDD',
borderWidth: 0,
outerRadius: '105%',
innerRadius: '103%'
}]
},
// the value axis
yAxis: {
min: 0,
max: 200,
minorTickInterval: 'auto',
minorTickWidth: 1,

tickPixelInterval: 30,
tickWidth: 2,
tickPosition: 'inside',
tickLength: 10,

from: 120,
to: 160,
color: '#DDDF0D' // yellow
}, {
from: 160,
to: 200,
color: '#DF5353' // red
}]
},
series: [{
name: 'Speed',
data: [80],
tooltip: {
valueSuffix: ' km/h'
}
}]
},
// Add some life
function (chart) {
setInterval(function() {
$(function() {
$.getJSON("livedata.php", function(data) {
$.each(data, function(key, val) {
if (key == 'Gas')
{
newVal = val;
var point = chart.series[0].points[0];
point.update(newVal);
}
});
});
}, "json");
}, 3000);
})
});
my simple test livedata.php is as follow:
// Set the JSON header
header("Content-type: text/json");
// The y value is a random number
$x = "Gas";
$y = rand(10, 100);
// Create a PHP array and echo it as JSON
$ret = array($x, $y);
echo json_encode($ret, JSON_NUMERIC_CHECK);
Can anybody tell me what is going wrong?
How can I test that the function is called?
How can I test that the livedata has passed?
