javascript Highcharts over option change backgroung color - javascript

I have 5 days trying to change color zone, this's code:
[https://jsfiddle.net/gerarca/7sg1c4nz/187/][1]
I just want to change backgroung color on over event, like:
enter image description here
If I put the mouse pointer over a department, an area should be highlighted in red, the area to which the department belongs.
I tried to do it using multiple overs, but this property can only be used once and don't work.
where I'm wrong??


Each department in your example refers to one point in the series. If you want to change the colour of the hovered point, you can use i.e point.events to achieve that:
point: {
events: {
mouseOver: function() {
originalColor = this.color;
this.update({
color: '#5F9EA0'
});
},
mouseOut: function() {
this.update({
color: originalColor
});
}
}
}
But if you want to change the colour of the zones and enable the dataLabels on hover, as like image shows, it would be best to create zones as a separate series. Then you will be able to easily update these series after mouseOver event.
Highcharts.mapChart('container', {
chart: {
map: topology
},
title: {
text: ''
},
plotOptions: {
series: {
dataLabels: {
enabled: false,
color: 'white',
format: '{point.name}'
},
color: 'grey',
allAreas: false,
states: {
hover: {
color: 'red'
}
},
events: {
mouseOver: function() {
this.update({
color: 'red',
dataLabels: {
enabled: true
}
}, false)
chart.update({}, true, false, false);
},
mouseOut: function() {
this.update({
color: 'grey',
dataLabels: {
enabled: false
}
}, false)
chart.update({}, true, false, false);
}
}
},
},
series: [{
data: zone1,
name: 'zone 1'
},
{
data: zone2,
name: 'zone 2'
},
{
data: zone3,
name: 'zone 3'
},
{
data: zone4,
name: 'zone 4'
},
{
data: zone5,
name: 'zone 5'
}
]
});

How to change event (hover & click) on legend item in highcharts?

You can see point value in the pie center if you are hovering chart points. Also you can see total value if you stop hovering chart point. It'd like the same behavior, if you're hovering legend item.
const chart = Highcharts.chart('container', {
chart: {
type: 'pie',
events: {
load: function(){
this.title.attr({text: this.series[0].total});
},
render: function() {
this.series && this.title.attr({y: this.plotHeight / 2 + this.plotTop + 5});
}
}
},
title: {
text: ''
},
legend: {
enabled: true,
},
plotOptions: {
pie: {
showInLegend: true,
innerSize: '50%',
dataLabels: {
enabled: false
},
point: {
events: {
mouseOver: function() {
this.series.chart.title.attr({text: this.y});
},
mouseOut: function(){
this.series.chart.title.attr({text: this.total});
},
}
}
}
},
series: [{
name: 'Brands',
colorByPoint: true,
data: [{
name: 'Microsoft Internet Explorer',
y: 56.33
}, {
name: 'Chrome',
y: 24.03,
}, {
name: 'Firefox',
y: 10.38
}]
}]
});
https://jsfiddle.net/q5fh1nog/24/
Also I want that clicking on active legend item will recalculate total value and show it in the center

You can add mouseover and mouseout event listeners on legend's elements and update the title in the same way as in point's events listeners. For example:
chart: {
type: 'pie',
events: {
load: function() {
const series = this.series[0];
this.title.attr({
text: this.series[0].total
});
series.points.forEach(point => {
['label', 'symbol'].forEach(prop => {
point.legendItem[prop].on('mouseover', () => {
series.chart.title.attr({
text: point.y
});
});
point.legendItem[prop].on('mouseout', () => {
series.chart.title.attr({
text: point.total
});
});
});
});
},
...
}
}

Apexcharts cursor pointer

I used apexcharts.js for making chartbar on js. So i want to change cursor to pointer. help please! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
my-code!
var options = {
series: [{
name: 'series1',
data: [60, 85, 75, 120, 100, 109, 97]
}],
toolbar: {
show: false,
},
chart: {
height: 350,
type: 'area',
fontFamily: 'Proxima Nova',
toolbar: {
show: false
},
},
dataLabels: {
enabled: false
},
stroke: {
curve: 'smooth'
},
xaxis: {
categories: ["Янв", "Фев", "Март", "Апр", "Май", "Июнь", "Июль", "Авг", "Сен", "Окт", "Ноя", "Дек"]
},
tooltip: {
x: {
format: 'dd/MM/yy HH:mm'
},
},
};
var chart = new ApexCharts(document.querySelector("#chart"), options);
chart.render();

I had encountered the same problem. I will present you two solutions:
1st method : Found on Github
You can set the cursor to point with:
chart: {
...
events: {
dataPointMouseEnter: function(event) {
event.path[0].style.cursor = "pointer";
}
}
}
See more details in this github link : https://github.com/apexcharts/apexcharts.js/issues/1466
2nd method : My own method
You can target the class name of the apexchart component via Inspector, then at the code level add the following property to this class :
cursor: pointer
Example :
// Change cursor on hover
.apexcharts-pie {
cursor: pointer;
}

I had same problem. Here is two solutions:
chart: {
width: 320,
type: ...,
events: {
dataPointMouseEnter: function(event) {
event.target.style.cursor = "pointer";
// or
event.fromElement.style.cursor = "pointer";
}
},
}

not working to update node of network graph

i'm using highchart to draw network graph.
and i want to change node's color.
my code to update node is
highchart.series[0].nodes[5].update({color: '#ff0000'});
it seem to work, but i get error like this.
Uncaught TypeError: Cannot read property 'concat' of undefined
at t.setNodeState [as setState]
i guess it's not working
when i update edge's node(has no "from or to" link) and move mouse on graph.
how i can update node's color?
enter image description here
const graphData = [
{from: 'Root', to: 'Group1'},
{from: 'Group1', to: 'Group1-1'},
{from: 'Group1-1', to: 'file1-1-1'},
{from: 'file1-1-1', to: 'asset1-1-1'},
{from: 'file1-1-1', to: 'asset1-1-2'},
];
const nodeData = [
{ id: 'Root', color: '#000000'},
{ id: 'Group1', color: '#00ff00' },
{ id: 'Group1-1', color: '#00ff00' },
{ id: 'file1-1-1', color: '#0000ff' },
{ id: 'asset1-1-1', color: '#d0d0d0' },
{ id: 'asset1-1-2', color: '#d0d0d0' },
];
const highchart = Highcharts.chart('highchart', {
chart: {
type: 'networkgraph',
plotBorderWidth: 1,
backgroundColor: 'transparent',
},
title: {
text: undefined
},
plotOptions: {
networkgraph: {
keys: ['from', 'to'],
layoutAlgorithm: {
enableSimulation: true,
linkLength: 100,
integration: 'verlet', // "euler"
},
link: {
width: 1,
color: '#B1B1B0',
dashStyle: 'Dash'
},
dataLabels: {
enabled: true,
y: -1,
style: {
fontSize: 10,
fontFamily: 'NotoSans-SemiBold',
textOutline: false
},
inside: false, // text 반전
textPath: {
enabled: false // circle 에 맞춰 text 곡선처리
},
linkTextPath: {
enabled: false
},
linkFormat: '',
},
point: {
events: {
update: function(param){
console.log('update', param)
}
}
}
},
},
tooltip: {
enabled: false
},
series: [{
name: 'Root',
id: 'Root',
allowPointSelect: true,
data: graphData,
nodes: nodeData,
}]
});
$('#btn').on('click', function(){
highchart.series[0].nodes[5].update({marker: {
fillcolor: '#ff0000'
}});
});
#highchart {
width: 500px;
height: 500px;
background: #f0f0f0;
}

<script src="https://code.highcharts.com/modules/networkgraph.js"></script>
<button id="btn">update</button>
<div id="highchart"></div>

The update feature doesn't exist for the nodes. It works for the points - https://api.highcharts.com/class-reference/Highcharts.Point#update
However, you can change the point color in this way:
highchart.series[0].nodes[5].graphic.css({
fill: 'red'
})

"point.select is not a function" at select events,Highcharts

I have problem when trying to overide the default behavior for scatter graph point selection to support multiple selection for single mouse left click.
My plotOption is :
plotOptions: {
scatter: {
point:{
events:{
click:function(e){
var point = this;
console.log(point ,"click")
point.select(true,true);
//e.preventDefault();
},
select:function(e){
var point = this;
console.log(point ,"select")
point.select(true,true);//just want to select somehow, but got error here
//e.preventDefault();// and then prevent the default behavior that will cause unselect of other points.
},
unselect:function(){
var point = this;
console.log(point ,"unselect");
}
}
},
marker: {
radius: 3,
states: {
hover: {
enabled: true,
lineColor: 'rgb(100,100,100)'
}
}
},
states: {
hover: {
marker: {
enabled: false
}
}
}
},
series : {
cursor:'pointer',
allowPointSelect: true,
marker:{
states:{
select:{
lineWidth:3,
lineColor:'#2cbfbe',
fillColor:'white',
radius:6
}
}
}
}
},
As you see , I call select(true,false) at both click and select events, but I have Uncaught TypeError: point.select is not a function at select events:

Highcharts + Highslide: When opening a new highslide popup or clicking anywhere else, close any previously opened popups

So, I discovered that when you have are utilizing highslides in conjuction with highcharts data, its possible to keep clicking new datapoints and have an endless number of modal windows pop up. I wanted to build something that will close an existing highslide popup window if you open a new highslide or if you click anywhere else, either on the screen or on a filter.
I wrote this little function and added it to my beginning statement but it did not work.
<body onclick="javascript:parent.window.hs.close();">
And here is my full example:
The question is, can someone show me an example where I can accomplish my above described behavior?

If allowMultipleInstances is set to false, opened expanders will close when you click to open another. Add this right after the included highslide.config.js file:
<script type="text/javascript">
hs.allowMultipleInstances = false;
</script>
