I'm using the following code so that if a person clicks on one of the candlesticks in the chart, the tooltip actually stays on the page:
events: {
click: function(event) {
if (cloneToolTip)
{
chart.container.firstChild.removeChild(cloneToolTip);
}
cloneToolTip = event.currentTarget.chart.tooltip.label.element.cloneNode(true);
chart.container.firstChild.appendChild(cloneToolTip);
I'd like to move this from the series to the chart so that they can click anywhere on the page and have the tooltip stay. However, event.currentTarget.chart doesn't exist if they don't click on a candlestick. I looking through the result and can't find the corresponding tooltip. Can someone shed some light on this for me? Much appreciated!!
You can use this instead of event.currentTarget.chart as the context is the chart itself. Hence this.tooltip should give you the tooltip that you are looking for.

I have a multi-series column chart in Highcharts with three series ("Western", "Eastern", and "Central"). Clicking the label of a series in the legend shows or hides the series. I'd like to add a little link at the end of each label with a link to download details about the underlying data for that series.
So a label would look like: Western (details)
I tried simply adding an <A> link to the "name" of the series, and the link appears, but clicking on it doesn't open the link. Instead, it merely toggles the series display as before. I guess the "onClick" event for the label itself supersedes the <A> behavior.
Is there any way, without hacking Highcharts or creating a whole custom legend, to make a link in a series label functional? Maybe something with CSS to make the link jump out of its parent element?
Your idea is very good. You need to only call e.stopPropagation() after click on a link to prevent toggling series.
Highcharts.chart('container', {
series: [{
name: 'Series name <a id="seriesDetails" href="https://www.google.pl/">Details</a>',
...
}]
});
document.getElementById('seriesDetails').addEventListener('click', function(e) {
e.stopPropagation();
// prevent redirect
//e.preventDefault();
console.log('click');
});

Currently it is possible for me to manually trigger hover event of highcharts like below code to show tooltip and highlight the series.
chart.series[0].points[2].onMouseOver()
However the state can be easily changed after moving the mouse.Is there a way for me to keep the state?
If you want to keep your tooltip visible when mouse pointer is out you need to disabled tooltip.hide functionality.
Highcharts.Tooltip.prototype.hide = function() {};
and highligt point again after mouse out:
events: {
mouseOut() {
let series = this;
series.points[2].onMouseOver();
}
}
Demo: https://jsfiddle.net/BlackLabel/xjzc25aL/
For those who are simply trying to make the tooltip visible for a longer time, there is the hideDelay property.
For example, to make it last 5 seconds you can write
chart.tooltip.options.hideDelay = 5000;
I need to make tooltip of some point make visible without moving mouse over the point. Say, I load my chart and have some tooltips already visible. Thanks for any help.
If you want the tooltip to show automatically on a point on load:
chart: {
events: {
load: function(){
// show tooltip on 4th point
var p = this.series[0].points[3];
this.tooltip.refresh(p);
}
}
},
Here's a fiddle.
Defaulty it is not available in the highcharts, but maybe better is using flags
I have a page which has a few links. Clicking on a link generates a list of different charts in the bottom of the page without page reload. Put it another way, each link clears previous charts, gets new data from the server, invokes Highcharts to draw new charts. No page reload.
Here comes the issue.
I am using the following Javascript to collect the charts on the page and send the data to the server.
var svgArray=[];
$(Highcharts.charts).each(function(i, chart){
if (chart) {
svgArray.push(chart.getSVG());
}
});
I notice that Highcharts.charts array grows by ADDING new charts to its end of when a link is clicked. I dont need old charts. I just want to collect new charts.
How can I initialize Highcharts or Highcharts.charts when a link is clicked.
Thanks and regards.
Here is what I did and it appears to get rid of charts created earlier. When a link is clicked and before the new charts get drawn, I try to destroy all charts the following way:
$(Highcharts.charts).each(function(i, chart){
if (chart) {
chart.destroy();
}
});
It seems working, but I am not sure if this is the right or best way or it can help others. I love to hear the input from experts.
Thanks!
I am noticing something strange; I have a click event on a chart, and the chart fire up the event no problem.
Then I add a link in the tooltip, but when I click on it; the chart event fire, not the one that should open the link.
It works only if the tooltip will render on an area that is not part of the plot area (say, a value is high enough to render a tooltip on the title bar; if I click on that link, it will work).
I suspect that there is some sort of parameter that tell highcharts if the link in the tooltip is above the chart plot area? Otherwise it is impossible to have the tooltip open a link, if the highcharts click event is enabled.
You need to set useHTML flag as true.
