Using the VU Guage: add the numeric value below needle - highcharts

In the Highcharts samples, I am seeing that the speedometer has a numeric indicator below the needle pivot (http://jsfiddle.net/radi8/kbvC3/497/). I am going to use the VU gauge but would like to add this numeric indicator to this gauge view. Playing with the fiddle (http://jsfiddle.net/radi8/Z2s77/1/), I cannot seem to get this element to display.
Any suggestions?

You have to enable and position dataLabels (now you have dataLabels: {enabled: false}).

Instead using tooltip.positioner you can set tooltip.followPointer to true:

Highcharts Gauge Chart with text labels

i have a gauge charts with defined tick positions and want to show some text labels there. e. g.:
-300 => Text 1
-200 => Text 2
-100 => Text 3
...
Is there a way to do that? Here's a fiddle of the chart.

}
}
},

}, {

to: 202,

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

]
}
}, {

color: {
linearGradient: {x1: 0, x2: 1, y1: 0, y2: 0},
stops: [
[0, '#DDDF0D'], //yellow
[1, '#ff0000'] //red
]
}
}]
}, {
min: -200,
max: 200,
lineColor: '#339',
tickColor: '#339',
minorTickColor: '#339',
offset: -100,
lineWidth: 2,

},

});
You can use a yAxis.labels.formatter function to check what the label value is, and return a text of your choice depending on that value.
To take your example, it could look like this:
yAxis: {
labels: {
formatter: function() {
if(this.value == -300) return '-300 => Text 1';
if(this.value == -200) return '-200 => Text 2';
if(this.value == -100) return '-100 => Text 3';
return this.value;
}
}
See this updated JSFiddle of how it works. As you can see you'll have to face the potential issue of labels overlapping the gauge, but you can fix that with distance, rotation and some other attributes (see API), depending on how your labels end up looking.

Highcharts VU Meter Gauge numeric display disapears

An interesting little "quirk" using the sample of the VU gauge. When I try to reposition the gauge pane, the numeric display will just disappear. If I keep the position <= 100%, the display will show, anything > 100% and the numeric display is gone.
I have repeatedly tried to force the display back into a position where it can be seen, but no luck. Any ideas? Here is the latest test fiddle:

Adjusting the elements is easy, use the pane: section to move the entire gauge with the display pane, use the datalabel: section to move the numeric display.

If you use the dataLabels.crop = false option it will show up. But based on the API description it will also show up if the data label is outside the plot area as well, which you may not want. The behavior by highcharts is weird though because it looks at whether the series is outside the plot area and not where the datalabel is when hiding the labels, so I agree that it is a bug.

How can you change the "label" (valueSuffix) on a highcharts gauge after the gauge has been created?

How can you change the "label" (valueSuffix) on a highcharts gauge after the gauge has been created?
something like this:
chart.series[0].remove();
chart.addSeries({
name: 'Speed',
data: [Math.random() * 200],
tooltip: {
valueSuffix: parseInt(Math.random() * 200, 16)
}
});

Yes it is possible by using html for yAxis title. Then you can use jquery or js to change div content.

highcharts Gauge live data with ajax

I have used highcharts library in my project and i have to update Gauge every 1 second with data creating by PHP file .
The highcharts Gauge Example have some code to make it trigger every 1 second , but i cant found some thing like This Link to get data from PHP file with Ajax Technic .
Anyone have any idea to implement this scenario and apply Ajax to this chart ?

inc = data.inc;
newVal = point.y + inc;
if (newVal < 0 || newVal > 200) {
newVal = point.y - inc;
}
point.update(newVal);
},"json");
}, 3000);
});
});​
In real world you use something like
$.post('new_data.php',{last_time: last_time},function(data) {
//set point here
},"json")
in new_data.php you do something like
$data=get_data($last_time);
echo json_encode($data);
exit;
