series.data would show an array of objects in the tooltip, but series.data[0] just gives undefined. How do I access the actual data and show in pointformatter (for example: I want to show the difference between every y value and the previous one without setting
compare: 'value')
The pointFormat doesn't support more than one nesting level. Use pointFormatter function which has more flexibility.
pointFormatter: function(){
var point = this,
series = point.series;
return `${series.name}: <b>${point.y}</b><br/>${series.data[0].y}`
}

Consider the following toy example: jsfiddle
chart: {
events: {
render: myfunc
}
},
...
function myfunc() {
var chart = this;
chart.series.forEach(function(s) {
s.setState('inactive', true);
});
chart.series[0].setState('hover');
}
The intended behavior is to set the state of the first series as hover while setting all other series as inactive after load and redraw events.
The code works as intended after load
However, it doesn't work after redraw (via the select box). After selecting an option in the box, the series are rendered as normal instead of as inactive UNLESS any series had been previously hovered. That is, the code works if you interact with any series AND THEN select an option in the box, but it doesn't work if you select an option in the box immediately after the loading without interacting on the series.
Surprisingly, after some inspection in the console, I noted that in any case the intended states are properly passed to the series object. So, why the states are not properly rendered?
*NOTE: In my actual application the hovered series is not necessarily the first one, but it varies depending on the output of other function. I'm aware that "myfunc" could be simplified in the current example, but for general purposes please suggest an answer keeping the basic structure if possible.
This seems to be related to this issue from HighChart's GitHub. In your case, HighCharts is correctly updating the series' state. However, while rendering it fails to set the proper opacity value associated with the 'inactive' state. The workaround is to explicitly set the opacity of the series to the same value it should have in the 'inactive' state.
// F U N C T I O N S E T S T A T E
function myfunc() {
var chart = this;
chart.series.forEach(function(s) {
//explicit opacity
s.opacity = 0.2;
s.setState('inactive', true);
});
chart.series[0].setState('hover');
}
Thank you for sharing this issue, it seems that it is a regression after the last release.
In the previous version it used to work fine: https://jsfiddle.net/BlackLabel/Lbpvdwam/
<script src="https://code.highcharts.com/8.1.0/highcharts.js"></script>
<script src="https://code.highcharts.com/8.1.0/highcharts-more.js"></script>
I reported it on Highcharts Github issue channel where you can follow this thread: https://github.com/highcharts/highcharts/issues/13719
If you don't need any new features/bugfixes use the previous version as a temporary workaround.
I'm having trouble creating and applying a tooltip to each of the images inside a div. The text of the tooltip should be the img's id. This seems like it would be fairly simple, so there must be something I am missing, or not understanding. Here's what I'm using:
$("#myDiv img").tooltip({
content:$(this).attr('id'),
track:true
});
Additionally, these images will be replaced depending on what the user clicks — once the images are deleted (by calling .empty on the containing div), do I need to delete the tooltips, or will they be automatically deleted from memory?
Sorry for the novice question!
You're attempting to get the id of all the img elements. Use .each to parse each element separately.
$("#myDiv img").each(function(){
$this = $(this);
$this.tooltip({
content: $this.attr('id'), // $this[0].id is faster
track: true
});
});
There is no need to remove the tooltip manually; the event bindings are deleted when the element is removed from the DOM.
Try this instead:
$("#myDiv").tooltip({
items: "img",
content: function() {
var el = $(this);
return el.attr( "id" ); // $this[0].id is faster
},
track: true
});

I have a unsort data (on x-axis) and using Highcharts to display the graph. I knew the x-axis must sort to show the tooltip as the Highcharts document wrote. But my data could not be sorted by some reasons, so could anyone meet this problem before, please give any idea/solution to show the tooltip without sort x-axis data. If I sort, my data will be wrong.
My js:
var data = [
[5.875, -20],
[8.1875, -30],
[8.875, -40],
[9.5, -50],
[10.125, -60],
[10.5, -70],
[10.875, -80],
[11.375, -90],
[11.6875, -100],
[11.875, -110],
[12.0625, -120],
[12.625, -130],
[12.4375, -140],
[12.625, -150],
[12.5, -160],
[12.4375, -170],
[12.4375, -180],
[12.375, -190],
[12.25, -200],
[12.1875, -210],
[11.9375, -220],
[11.625, -230],
[11.5, -240],
[11.125, -250],
[10.75, -260],
[10.625, -270]
];
$('#container').highcharts({
series: [{
data: data
}]
});

Thank you so much and have a nice day.
You have two options:
sort your data: http://jsfiddle.net/jedLowyv/5/
use scatter series with lineWidth: http://jsfiddle.net/jedLowyv/6/ (not: tooltip will show up only when hover one of markers directly)
I have a very simple question, which I can't find a solution.
when I use the click event; I log this.id, which return undefined when I am on a rendered HighCharts.
Why is that? How can I actually get the elementID where the chart is, so I can use functions that call that element? The chart is rendered on a div class, which is used for all the charts on my page (each with different ID obviously).
Event.target returns me a rect, which I can use to a certain extent, with document.mouseup, but I would like to learn how you actually identify the chart, fi I want to access it
For example, I would like to use fancybox, but it require an ID to work
$("#ID").fancybox();
EDIT:
I am able to open the chart using the href parameter, where I render the chart; but still; I have no clue how to identify programmatically a chart, once is rendered, in the click event.
Assuming you are using the chart click event and you want the original div container:
chart: {
events: {
click: function (event) {
var myDiv = this.container.parentElement;
}
}
},
This will return the element.
I am drawing various charts on a page, and would like to avoid to have to declare in each chart, the properties that are common to every chart.
I tried an example found online, where the common part was in a {settings}, but when I try to load it, I had no luck.
I am using Highcharts. Any suggestion is more than welcome....with 16 charts on one page, I am just going crazy.
You can use merge function. See the example:
http://jsfiddle.net/nyQ2L/
var defaultOptions = {
chart:{
type:'line'
},
title: {
text:'common title'
}
};
var opt1 = Highcharts.merge(defaultOptions,{
series:[{
data:[1,2,3]
}]
});
