I'd like to remove the value box from a Highcharts angular gauge.
I'm not sure it is possible...I have tried messing around with the JSFiddle demo trying to remove it and haven't been able to.
I was able to remove the minor and major ticks by adding
minorTickInterval: 'none',
tickPixelInterval: 'none'
But I can't figure out how to remove the value from the middle of the gauge.
or you can achieve the result you want just by adding the following lines:
series: [{
dataLabels: {
enabled: false
}
}]
You should add dataLabels.formatter to the series part of your gauge to remove it.
dataLabels: {
formatter: function () {
return null;
}
},

I want to use Accessible line chart of Highcharts (https://www.highcharts.com/demo/accessible-line)
In demo, I saw some series label position on last point, some in middle and first point.
How can I set all series label on last point?
Sorry for my bad English!
You can use data labels instead of series labels.
Example:
plotOptions: {
series: {
dataLabels: {
enabled: true,
formatter: function() {
if (this.point.index === this.series.points.length - 1) {
return this.series.name;
}
}
},
...
}
}

I want to draw a line on a ohlc chart, but i dont want the new series to introduce gaps.
The first series (ohlc) should still place the candles in an nica way with constant gaps between them regardles of open-close times (i think its only the "ordinal" value that does this, but unfortunatelly you cant specify it at series level, but only axis level).
xAxis: {
ordinal: true
},
example:
http://jsfiddle.net/5r97owky/8/
Thank you for any help
The gaps are caused by ordinal option. You can create additional xAxis for line series:
Highcharts.stockChart('container', {
chart: {
events: {
load: function() {
var xAxes = this.xAxis,
extremes = xAxes[0].getExtremes();
xAxes[1].setExtremes(extremes.min, extremes.max, true, false);
}
}
},
xAxis: [{}, {
visible: false
}],
...
});

I'm trying to add SMA (Simple moving average) into my highstock with dataGrouping.
dataGrouping works fine without SMA. But when I add SMA it only group data on daily basis. Has anyone got the same problem?
I've checked the chart element and I can see the series & SMA object they all got the dataGrouping attribute but still not display properly in the chart.
I tried to add dataGrouping in both plotOptions.series & plotOptions.sma or add it in series respectively but none of them work.
let dataGrouping = {
forced: true,
units: [
['week', [1]],
]
};
const options = {
//...
plotOptions: {
candlestick: {
color: 'green',
upColor: '#e00000',
},
series: {
marker: {
enabled: false,
},
states: {
hover: {
enabled: true,
lineWidth: 1.5,
}
},
dataGrouping,
},
sma: {
dataGrouping,
}
},
}
My highcharts verion is 6.0.7
I also tried to add dataGrouping on an official example and here's the link: http://jsfiddle.net/tuuz4yho/8/
and here's another example with a simple line chart
https://jsfiddle.net/Lyf6vzev/19/
But dataGrouping still not work on SMA lines.
Anyone know how to group SMA weekly or monthly?
Really need your help!
Thanks! :)
Turns out it's a known bug:
https://github.com/highcharts/highcharts/issues/7823
The workaround is setting dataGrouping.approximation and dataGrouping.groupPixelWidth in the indicator config.
I use Highcharts to visualize 3D charts in my project. Particularly I am interested in showing a 3D scatter plot like this. Below the chart you can see the options as well as the respective jsFiddle.
Is there a possibility to display a label with every point's name always i.e. that hovering is not required?
Thanks!
Within the series you can enable the datalabels like this:
series: [{
dataLabels: {
enabled: true,
},
}]
http://jsfiddle.net/oghokm8w/1/
then you could use the formatter to customise the text to be displayed:
series: [{
dataLabels: {
enabled: true,
formatter: function () {
return this.point.x;
},
}
}]
Is there a preferred way to eliminate or aggregate labels below a certain threshold when using HighCharts pie chart? I'd rather not have to rollup all values below a certain percentage into 'other' if I can. I've checked the docs and can't find anything. It would be very useful!
Thanks in anticipation.
The best way to achieve this is to use dataLabels formatter for pie chart like this:
plotOptions: {
pie: {
dataLabels: {
formatter: function(){
if (this.percentage < SOME_VALUE) return "";
return VALUE_TO_SHOW;
}
}
}
}
Replace SOME_VALUE and VALUE_TOSHOW with desired values. But there will be some problems if you're using connector for you labels (it is always visible).
A very late answer to this question:
If instead of returning empty string, you instead return null, the label AND connector will not show, and you'll be able to achieve this effect without removing the connector:
Example: jsfiddle
plotOptions: {
pie: {
dataLabels: {
formatter: function(){
if (this.percentage < SOME_VALUE) return null;
return VALUE_TO_SHOW;
}
}
}
}
