How to change the marker style on hover in HighCharts - highcharts

When I hover over a marker in a chart, how can I remove the larger opaque circle behind the marker.

Halo can be adjusted using options described in Highcharts API reference: http://api.highcharts.com/highcharts#plotOptions.line.states.hover.halo
Example:
plotOptions: {
series: {
states: {
hover: {
halo: {
size: 0
}
}
}
}
},

How to center the title text in pie chart highchart?

I am trying to do center align the title text of the pie chart Highchart. Was able to achieve that but on mouse hover, and mouse out the title data doesn't get updated. Anyone can help me with the same.
On MouseHOver trying to do the below mentioned code
point: {
events: {
mouseOver: function() {
let span = '<span style="color:${this.color}" class="dealer-title">${this.y}<br/> <span style="color:#33383e;}" class="text-truncate" title="${this.name}"><b> </b></span></span>';
$('.customTitle')[0].innerHTML = span
}
}
}
}
},
fiddle attached:

You need to enable useHTML argument in the text method call:
chart: {
type: 'pie',
events: {
load: function() {
...
var text = rend.text("textTexttext", left, top, true).attr({
'text-anchor': 'middle',
align: 'center',
'zIndex': 10
}).addClass('customTitle').add();
}
}
}

API Reference: https://api.highcharts.com/class-reference/Highcharts.SVGRenderer#text
It looks like you can't include html tags in the title. If you remove the SPANs it'll display the values.
$('.customTitle')[0].innerHTML = this.y

Highcharts drilldown treemap legend

I'm working on a drilldown treemap and the render is exactly what I want.
My problem is about the legend.
I used colorAxis for the drilldown level and I would like to hide the legend on the main level (one color by tile) but display the graduate color axis legend on the sub level, only for the sub-serie displayed.
I made an example here : http://jsfiddle.net/vegaelce/4dLopjwv
I used the property legend to display it :
legend: {
enabled: true
},
but it displays the legend of each colorAxis on the sublevel.
How can I hide all the legend except the one corresponding to the sub-serie displayed ?
Thanks in advance
You can use drilldown and drillup events and update the visible property of the right color axis.
chart: {
type: 'treemap',
events: {
drilldown: function(e) {
const colorAxis = this.colorAxis[e.seriesOptions.colorAxis];
if (colorAxis) {
colorAxis.update({
visible: true
}, false);
}
},
drillup: function() {
this.colorAxis.forEach(function(cAxis){
if (cAxis.visible) {
cAxis.update({
visible: false
}, false);
}
});
}
}
}

Stop HighCharts change transparency of another series on hover of one series

By default , when i hover on one series , other series get some transparent.
How can i disable this behavior?
this hover: { enabled: false} not working.
You need to change the opacity property for inactive state:
plotOptions: {
series: {
states: {
inactive: {
opacity: 1
}
}
}
}

Highcharts -- exporting, setting dataLabel options

I've using Highcharts 2.3.5. In the "exporting' object, under "chartOptions", I'm able to change some things when exporting, like the background color of the chart, but I haven't been able to enable the dataLabels nor change the marker size.
Here's an example, of what works and doesn't work. In this case, when exporting, I want to change the background color (which works) and make sure the data labels appear (which doesn't work) :
...
exporting : {
chartOptions : {
chart: { backgroundColor: '#ff0000'}, //this works
plotOptions: {
pie : {
dataLabels: {enabled: true} //this one doesn't work
}
}
}...
Am I missing something obvious?
j
$('#container1').highcharts({
exporting: {
chartOptions: { // specific options for the exported image
plotOptions: {
series: {
dataLabels: {
enabled: true
}
}
}
},
scale: 3,
fallbackToExportServer: false
},
