want to remove this bullet in front of these labels of highcharts graph

i am using highcharts solid gauge. below is sample i have created
now i want to remove these grey bullets as these are not coming in my local but in test its there, i havn't got anything helpful from api. here are options passing to this.and thus i am not sure what i am missing can anyone guide me as i have tried looking into api for solid gauge but i am not sure which option is there to help me

I think you can just apply a style to the class highcharts creates to hide these markers:
.highcharts-legend-item rect {
display: none;
}

I'm not familiar with highcharts, but those bullets looks like the work of a <ul> element.
You can remove bullets from all ul elements using css, like this:
ul
{
list-style-type:none;
}
See list-style-type. Of course it is better to specify the #id of the particular ul element, but (above) is just an example.

It's not possible to remove legend symbols and keep series markers. As a workaround, you can remove them manually in the chart load event callback.
Code:
chart: {
type: "solidgauge",
events: {
load: function() {
var chart = this,
series = chart.series;
series.forEach(function(serie, i) {
if (serie.legendSymbol) {
serie.legendSymbol.destroy()
}
});
}
}
}

Highcharts angular wrapper labels.items don't refresh

I'm using angular6 and the office highcharts angular wrapper (https://github.com/highcharts/highcharts-angular) in version 2.4.0.
Everything is working good except the labels that can be placed manually on the chart.
I just don't manage to get them refreshed.
I have a graph that can be filtered through the back-end. When I get the new generated data I update the data in my chartOptions which are used in the html as [options]="chartOptions" for the angular component.
The chartOptions are instanciated from my default class like this: this.chartOptions = new GraphConfigSeqAtteptedVsAchived().chartOptions;
The Class looks like this:
`import * as Highcharts from 'highcharts';
export class GraphConfigSeqAtteptedVsAchived{
public chartOptions: any;
constructor(){
this.chartOptions = {
chart: {
height: 600,

this.myTooltip = new Highcharts.Tooltip(this, this.options.tooltip);
}

}
}
}`
The generated data is in the typescript dynamically added and all of that works just fine. Everything is refreshed after I set the updateFlag for [(update)]="updateGraph". The axis titles are also fine.
The only thing that's not refreshed for me are the labels i dynamically added to the chart like this:
let labelTotalNumberOfEyes = {
html : this.translate.instant('GRAPHS.TOTAL_NUMBER_OF_EYES') + ': ' + (scatterSeries.data.length + scatterSeriesRetreatment.data.length),
style : {
left : '330px',
top : '368px',
fontSize : '14px',
backgroundColor: '#FFFFFF',
borderWidth: 1,
}
}
this.chartOptions.labels.items.push(labelTotalNumberOfEyes);
Does someone have any idea what I'm might doing wrong? I don't see any further option than just setting this update flag and it works fine for everything but the labels.
Please let me know if you're missing any information.
Thanks in advance.

This issue is actually a Highcharts bug. I've reported it here: https://github.com/highcharts/highcharts/issues/10429.
As a workaround, you can use Highcharts.SVGRenderer to add a custom label and store reference to it in your component. Next, when updating, call attr() method on the label (Highcharts.SVGElement) and set new options. Check demo and code posted below.
Add a label on chart callback:
constructor() {
const self = this;
this.chartCallback = chart => {
self.chart = chart;
self.label = chart.renderer
.text("test", 100, 100)
.css({
fill: "#555",
fontSize: 16
})
.add()
.toFront();
};
}
call attr() on the label while updating:
update_chart() {
const self = this,
chart = this.chart;
chart.showLoading();
setTimeout(() => {
chart.hideLoading();
self.chartOptions.series = [
{
data: [10, 25, 15],
name: "updatedSerieName"
}
];
self.chartOptions.yAxis.title.text = "updatedData";
self.label
.attr({
text: "test1",
x: 150,
y: 120
})
.css({
fill: "red",
fontSize: 20
});
self.updateFromInput = true;
}, 2000);
}

Sometimes It is not displaying any line or dot. instead of that simply showing alternate text that is Created with Highcharts 4.0.1. What would be the issue? how can resolve this?

Highcharts AreaSpline - Adding padding in between the chart and plot area

I am trying to add padding in between my chart and plot area, as you can see in the screenshot below, the markers are overflowing across the borders of the plot area.
Is there a way for me to add padding to the bottom of the plot area, or a way to move up the chart series slightly so that it doesn't overflow?
Here is a fiddle: http://jsfiddle.net/H3Asy/5/
Here is the JS code:
$('#container').highcharts({

There is no perfect solution for that, but only two workarounds:
set min and startOnTick for xAxis, demo: http://jsfiddle.net/H3Asy/6/
yAxis: {
min: -1024 * 1024 * 1024,
startOnTick: false,
}
set threshold for series and startOnTick for xAxis, demo: http://jsfiddle.net/H3Asy/7/
yAxis: {
startOnTick: false
},
plotOptions: {
areaspline: {
threshold: -1
}
}

Set Colors of Different Points when Clicking on Pie Slice Legend

I would like to set all colors for the pie slices to gray except for the color pie slice clicked in the legend. I have been only able to figure out how to change the color of only the clicked legend item not the others.
I have tried setting id's to the data points and using e.target but that didn't provide the proper access.
Thanks for your help.
Here is my myFiddle.
$(document).ready(function () {
var myCharts = {
chart: {
renderTo: 'container',
type: 'pie',
backgroundColor: 'rgba(255, 255, 255, 0.1)',
borderColor: 'rgba(255, 255, 255, 0.1)',

},

'#0066FF',
'#33CC33',

'#FFFF00',
],

},

}
},

},
xAxis: {

},
plotOptions: {
pie: {
states: {
hover: {

}
},
point: {
events: {
legendItemClick: function () {
this.graphic.attr({
fill: '#CCCCCC'
});
return false
}
}
},
dataLabels: {
enabled: true,
distance: 0.1,
color: 'black',
formatter: function () {
return '<b>' + this.point.name + '</b>: ' + this.percentage + ' %';
},
},
innerSize: '60%',
shadow: true,
size: '100%',
allowPointSelect: true,
slicedOffset: 10,
}
},
tooltip: {
enabled: false
},
series: [{
data: [],
showInLegend: true,
}]
};
myCharts.chart.renderTo = 'container';
myCharts.title.text = 'Net Activations';
var actual = 52,
goal = 73 - actual,
ATB = 100 - goal - actual;
myCharts.series[0].data = [{
name: 'Actual',
y: actual,
id: 0
}, {
name: 'goal',
y: goal,
id: 1
}, {
name: 'ATB',
y: ATB,
id: 2
}];
new Highcharts.Chart(myCharts);
});

Instead of attacking the SVG directly with this.graphic.attr, you'd be better off using the API to update the slice. Point.update works well for this:
legendItemClick: function () {
var series = this.series;
for (var i=0; i < series.data.length; i++){
var point = series.data[i];
if (point == this){
// set back to old color
point.update({color: series.chart.options.colors[this.id]});
}else{
// make it gray
point.update({color: '#CCCCCC'});
}
}
return false;
}
Updated fiddle here.

Well, I can get you 50% of the way there:
point: {
events: {
click: function () {
if (event.point.sliced) {
$.each(this.series.data, function (i, e) {
if (!e.sliced) {
this.graphic.attr({
fill: '#CCCCCC'
});
}
});
}
}
}
This still breaks when you re-click the slice to slot it back in - the colors of the other slices are still grey until you click on them. Will need to look more into this.
