I have one chart and i want to include hover on area but i found it works only on point only.
series: [{
name: 'Target',
type: 'polygon',
data: [[153, 42], [149, 46], [149, 55], [152, 60]],
color: Highcharts.Color(Highcharts.getOptions().colors[0]).setOpacity(0.5).get(),
enableMouseTracking: true
}],
tooltip: {
headerFormat: '<b>{series.name}</b><br>',
pointFormat: '{point.x} cm, {point.y} kg'
}
http://jsfiddle.net/onhfLqdm/3/
As area is bounded by points so how can i hover area instead of points?
Update On hover on each polygon asker wants to show data coming from json.To do so in a div out of container please view this fiddle
In Tooltip One more option to show some info coming from json ,tooltip can be used.Put your data using some name like "someText" (as in my fiddle )and get it in formatter function of tooltip using
this.options.someText
See this fiddle for data in tooltiip
Old Answer:
plotOptions: {
series: {
events: {
mouseOver: function () {
$("#polygon").html('Moused over Event')
.css('color', 'green');
},
mouseOut: function () {
$("#polygon").html('Moused out Event')
.css('color', 'red');
}
}
}
}

Using Highstock, I wish to draw a candlestick chart over a line chart.
I know it sounds weird, but I need to rotate the candlestick chart by 90 degrees clockwise.
The code I have now is:
Highcharts.getJSON('https://cdn.jsdelivr.net/gh/highcharts/highcharts#v7.0.0/samples/data/new-intraday.json', function (data) {
// create the chart
Highcharts.stockChart('container', {
title: {
text: 'AAPL stock price by minute'
},
navigator: {
enabled: false
},
rangeSelector: {
enabled: false
},
series: [{
name: 'AAPL',
type: 'candlestick',
data: data,
tooltip: {
valueDecimals: 2
}
},{
name: 'TEST',
type: 'line',
data: data
}]
});
});
JSFiddle here
What I want to get is the following (something like...):
Any (simple) idea?
Highstock is not adapted to this kind of customization. The only simple way seems to be creating two overlapping charts - one inverted and one with transparent background, but we have to take into account many limitations, like for example tooltip.
chart: {
inverted: true,
...
}
Live demo: https://jsfiddle.net/BlackLabel/nb1jyaq5/
API Reference: https://api.highcharts.com/highcharts/chart.inverted
When using Highcharts Navigator the docs mention:
Unless data is explicitly defined on navigator.series, the data is borrowed from the first series in the chart.
$(function () {
$('#container').highcharts('StockChart', {
navigator: {
series: {
lineWidth: 1
}
},
rangeSelector: {
selected: 1
},
series: [{
name: 'USD to EUR',
data: usdeur
}]
});
});
But as in the example of Highcharts Navigator itself here the data is not exactly the data from the first series in the chart. In this example the date is between 2007-2015 but navigator only shows 2008-2014. Is there a way to override this option? How can I change this?
I am trying to change the sliced point colour on pie chart. When it is drilled down, the colour couldn't be changed using the select function on the slice. The colour is always changed back to the colour of its parent slice.
For example, when a green slice is clicked on the parent chart to drill down, whatever slice clicked on the child chart will change to green, even though I tried to change it to yellow in the select event which is set in plotOptions. But unselecting it will change the colour to yellow, by clicking another slice.
It seems like a bug to me.
$('#container').highcharts({
chart: {
type: 'pie'
},
title: {
text: 'Browser market shares. November, 2013.'
},
subtitle: {
text: 'Click the slices to view versions. Source: netmarketshare.com.'
},
plotOptions: {
series: {
allowPointSelect: true,
point: {
events: {
select: function() {
this.update({color: 'yellow'});
}
}
},
dataLabels: {
enabled: true,
format: '{point.name}: {point.y:.1f}%'
}
}
},
tooltip: {
headerFormat: '<span style="font-size:11px">{series.name}</span><br>',
pointFormat: '<span style="color:{point.color}">{point.name}</span>: <b>{point.y:.2f}%</b> of total<br/>'
},
series: [{
name: 'Brands',
colorByPoint: true,
data: brandsData
}],
drilldown: {
series: drilldownSeries
}
});
Here is the fiddle.
In the current version of the Highcharts (Highcharts Basic v7.2.1) everything is working properly.
I'm a bit late on this one, but this is a known issue of Highcharts. Instead of using the select event, use the selected and unselected events. There is a subtle difference here, as using select will often not fire directly after a click. These two events however are more reliable.

I have a problem with click events on heatmaps: it works only if you click on a tooltip, but not on the chart itself. See the demo http://jsfiddle.net/3UWaA/1/
chart: {
type: 'heatmap',
events: {
click: function(event) {
alert("clicked!");
}
}
}
Any suggestions how to fix this?
Thanks
Add the events into a plotOptions object.
Like this:
plotOptions: {
series: {
events: {
click: function (event) {
alert('event!');
}
}
}
},
Demo: http://jsfiddle.net/robschmuecker/3UWaA/3/
Because click event on chart, works in the plotArea, not on the serie. Heatmap serie overlap plotArea, so click event doesnt work. You need to catch plotOptions event on serie / point.
Try inserting the EVENTS: under series block and disable the tooltip as below:
series:
[
{ name: 'Passed',
borderWidth: '1',
borderColor: '#000000',
cursor: 'pointer',
events:
{
click: function ()
{
alert('wow');
}
},
color:'green',
data: [[0, 1, ''],[0, 2, ''],[0, 3, '']],
dataLabels:
{
enabled: 'true',
color: '#000000'
}
}
]
So when you click the chart itself,click event will work fine.
Steps to reproduce.
We have a chart that display 4 series of data, and we have the corresponding legends with each series.
THe initial chart is loaded with 1 years worth of data.
We then remove all data-series from the chart by clicking on the 4 legends
We then change the Zoom level of the chart - e.g. going from a 6 month zoom, to a 3 month zoom. (NOTE: We change Zoom with no data-series being displayed).
We then re-enable the data-series by clicking on the legends.
The chart does not redraw correctly. To get the chart to redraw we have to reload the entire page.

// As we're loading the data asynchronously, we don't know what order it will arrive. So

seriesCounter++;
if (seriesCounter == names.length) {

// create the chart when all data is loaded

JsFiddle Example
It looks like a bug, so I've reported it to our devs here: https://github.com/highslide-software/highcharts.com/issues/1568
A simple workaround :
After some trial and error, I found out that if you do not disable the navigator, the above bug is not exhibited. (Navigator is enabled by default.)
Comment the line as shown below:
navigator: {
//enabled: false
}
Js Fiddle : http://jsfiddle.net/msjaiswal/FDXBu/1/
Certainly this is a bug in Highcharts but we can live with this above simple workaround.
This issue has been resolved in version 1.3.2 of HighStock.
