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

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

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 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?

How to disable tooltip in highcharts gauge?

I try to disable tooltip for gauge but no matter what I do, it doesn't work.
I tried to place:
tooltip: {
enabled: false
}
under chart, pane, series ...
Here is a demo I use: Fiddle
and this is a code:
$('#container').highcharts({

padding: 5,
shadow: true,

fontWeight: 'bold',
fontSize:'25px'
}
},
}]
});
Any ideas?

Try adding it to the config object itslef?
http://jsfiddle.net/hesonazx/
$('#container').highcharts({
tooltip: {
enabled: false
},
chart: {
...
});
This is based on the documentation. Notice that the toottip property for a guage type chart doesn't have an enabled option. The general tooltip property does however.

You can just add .highcharts-tooltip{opacity: 0;}

HighCharts speed o meter query

I am using highcharts speed o meter with PHP and MYSQL. It is working fine but the problem is that when I merge the JavaScript in my website, the speed o meter is not displaying. It does not appear any error, just blank screen where the speed o meter code is used. Here is my code:
$(function () {
$('#containers').highcharts({
chart: {
type: 'gauge',
plotBackgroundColor: null,
plotBackgroundImage: null,
plotBorderWidth: 0,
plotShadow: false
},
title: {
text: ''
},
pane: {
startAngle: -90,
endAngle: 90,
center: ['50%', '100%'],
background: [{
backgroundColor: {
linearGradient: { x1: 0, y1: 0, x2: 0, y2: 1 },
stops: [
[0, '#FFF'],
[1, '#333']
]
},
borderWidth: 0,
outerRadius: '109%'
}, {
backgroundColor: {
linearGradient: { x1: 0, y1: 0, x2: 0, y2: 1 },
stops: [
[0, '#333'],
[1, '#FFF']
]
},
borderWidth: 1,
outerRadius: '107%'
}, {
// default background
}, {
backgroundColor: '#DDD',
borderWidth: 0,
outerRadius: '105%',
innerRadius: '103%'
}]
},
// the value axis
yAxis: {
min: 0,
max: 200,
minorTickInterval: 'auto',
minorTickWidth: 1,
minorTickLength: 10,
minorTickPosition: 'inside',
minorTickColor: '#666',
tickPixelInterval: 30,
tickWidth: 2,
tickPosition: 'inside',
tickLength: 10,
tickColor: '#666',
labels: {
step: 2,
rotation: 'auto'
},
title: {
text: 'Speed km/h'
},
plotBands: [{
from: 0,
to: 120,
color: '#55BF3B' // green
}, {
from: 120,
to: 160,
color: '#DDDF0D' // yellow
}, {
from: 160,
to: 200,
color: '#DF5353' // red
}]
},
series: [{
name: 'Speed',
data: [<?php echo join($result, ',') ?>],
tooltip: {
valueSuffix: ' km/h'
}
}]
},
// Add some life
function (chart) {
if (!chart.renderer.forExport) {
}
});
});
I don't know what is problem if any one knows please tell me.

The only thing i see is that you forgot a semi-colon:
<?php echo join($result, ',') ?>
Change to
<?php echo join($result, ','); ?>
Otherwise try the console-debugger for the javascript-part.

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({

type: 'gauge',
plotBackgroundColor: null,
plotBackgroundImage: null,
plotBorderWidth: 0,

background: [{
backgroundColor: {
linearGradient: { x1: 0, y1: 0, x2: 0, y2: 1 },

[0, '#FFF'],
[1, '#333']

backgroundColor: {
linearGradient: { x1: 0, y1: 0, x2: 0, y2: 1 },

]
},
borderWidth: 1,

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

minorTickInterval: 'auto',
minorTickWidth: 1,
minorTickLength: 10,
minorTickPosition: 'inside',

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

color: '#DF5353' // red
}]
},
series: [{
name: 'Speed',
data: [80],
tooltip: {

}
}]
},
// 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?
