In short, I need to somehow enable groupPadding for stacked series. It looks a little bit odd, but this is what you can do in PowerPoint if you set series overlap to 0:
With series overlap set to 100, they would be on top of each other like in Highcharts with stacking set to e.g. normal.
To me, it seems you are not allowed to move stacking columns horizontally relative to each other in Highcharts. But maybe I am missing something or there is a workaround?
Thanks!
You can create an additional hidden series with the same stack as the upper series. Example:
Highcharts.chart('container', {
chart: {
type: 'column'
},
plotOptions: {
column: {
stacking: 'normal',
pointPadding: 0,
dataLabels: {
enabled: true,
format: '{point.y}%'
}
}
},
series: [{
data: data2,
color: 'gray'
}, {
data: data1,
color: 'rgba(0,0,0,0)',
linkedTo: 'data1',
dataLabels: {
enabled: false
}
}, {
id: 'data1',
data: data1,
stack: 'A',
color: 'green'
}]
});

I'm using Highcharts in an Angular 8 application, and while the chart itself renders quite fast, I am encountering some seriously degraded performance rendering tooltips on charts bound to larger data sets. Interestingly the issue seems less related to the number of data points than to the amount of the plot area series fill.
We are using Boost (in app.module.ts):
Boost(Highcharts);
NoData(Highcharts);
More(Highcharts);
NoData(Highcharts);
theme(Highcharts);
and this is is the chart's config (series are added dynamically):
public baseChartOptions: Highcharts.Options = {
chart: {
type: 'line',
zoomType: 'x',
animation: false,
height: '55%'
},
boost: {
enabled: true,
useGPUTranslations: true,
usePreallocated: true
},
legend: {
enabled: true,
align: 'center',
verticalAlign: 'bottom',
layout: 'horizontal'
},
exporting: { enabled: false },
plotOptions: {
series: {
lineWidth: 1.5,
animation: false,
marker: {
enabled: false
}
}
},
xAxis: [
{
type: 'datetime',
dateTimeLabelFormats: {
day: '%m/%d'
}
} as Highcharts.XAxisOptions
],
yAxis: [
{
minorTickLength: 0,
tickLength: 0,
title: {
text: ''
}
}
],
tooltip: {
shared: true,
pointFormat: '<span style="color:{point.color}">\u25CF</span> {series.name}: <b>{point.y:.0f}</b><br/>',
animation: false
},
series: []
};
What are best practices for ensuring the best performance in rendering tooltips? I've seen the Highcharts demo showing over 1,000,000 points with good performance, but I don't seem to be able to achieve the same.
I've included a short video converted to gif that illustrates the behavior I'm seeing at three different data densities.
Thanks for your help!
highcharts tooltip performance
The performance should be better when you disable shared tooltip:
tooltip: {
animation: false,
valueDecimals: 2,
shared: false
}

Hello I am currently facing a problem with the tooltip on my chart which adds data dynamically through the use of Series.SetData() function of highcharts.
The issue however is not related to the data which is added I think but with the tooltip everytime I mouse over a point in the graph.
To better understand I will post two screenshots with the issue:
Whenever I mouse over a certain point in the graph the tooltip keeps changing and the values presented are the ones posted in the screenshots. If I drag the mouse away the tooltip that remains on the screen is the second one and I am no longer able to see the Y1 value.
I probably have some bad chart configuration so here is the code of my graph:
$(function () {
// Create the chart for node 1
$('#container').highcharts('StockChart', {
chart: {
zoomType: 'x',
events: {
load: requestDataNode1
},
},
credits: {
enabled: false
},
title: {
text: 'Live Data'
},
rangeSelector: {
buttons: [{
count: 1,
type: 'minute',
text: '1M'
}, {
count: 5,
type: 'minute',
text: '5M'
}, {
type: 'all',
text: 'All'
}],
inputEnabled: false,
selected: 0
},
yAxis: {
labels: {
formatter: function () {
//return (this.value > 0 ? ' + ' : '') + this.value + '%';
return this.value;
}
},
plotLines: [{
value: 0,
width: 2,
color: 'silver'
}]
},
legend:{ enabled: true},
plotOptions: {
series: {
showInNavigator: true
},
spline: {
turboThreshold: 0,
dataLabels: {
enabled: false
},
enableMouseTracking: true
}
},
tooltip: {
pointFormat: '<span style="color:{series.color}">{series.name}</span>: <b>{point.y}</b><br/>',
valueDecimals: 2,
split: false
},
navigator: {
series: {
data: []
}
},
});
});
I do not know why this happens , at first I thought it could be related with not having a value for a series for a specific date but then I checked my series as you can see in the screenshots and there is indeed a value for both series.
I thank in advance for your help.
I somehow resolved this issue by adding the shared property in the tooltip property and setting to false, however now I only receive a single value.
Is it possible to keep seeing all values?
I'm generating a series of highcharts and then exporting them to a pdf via jsPDF. They display fine on screen, but when I export an image of the graphs, it duplicates the X axis category labels.
Here is my chart code:
$('#chart').highcharts({
chart: {
type: 'column',
spacingBottom: 0,
spacingTop: 20,
spacingLeft: 0,
spacingRight: 0
},
exporting: {
enabled: false
},
credits: {
enabled: false
},
title: {
text: null
},
legend: {
enabled: false
},
xAxis: {
categories: ['Sales Performance',],
labels: {
style: {
color: '#000'
}
}
},
yAxis: {
title: {
text: null
},
labels: {
format: '{value}%',
overflow: 'justify',
style: {
color: '#000'
}
}
},
plotOptions: {
series: {
stacking: 'normal'
}
},
tooltip: {
valueSuffix: '%'
},
series: [{
name: '% Change',
color: '#c0504d',
data: [4.5]
}]
});
And an example of the issue: http://jsfiddle.net/212qb8qs/
Any ideas???
UPDATE:
The issue was with canvg converting the svg. Solved thanks to this comment: When using canvg to convert Highchart SVG into PNG, all text appears twice - how to solve?
Well, from your jsfiddle, you use canvg along with highcharts to get a canvas and then convert to PDF what you get. The problem comes from canvg wich seems to handle a bit strangely the tspan that are used in the SVG generated by highcharts (mostly for titles).
So I redirect you to my answer in another question here , where you'll find a dirty fix for that.
Highcharts v3.01
I'm trying to use a scatter plot to draw points within named categories (these are actually numeric, but out of series and I don't want gaps).
Using line graph types would work, but I'd rather not as I have potentially hundreds of series and scatter points are clearer.
The closest I have come is this:
EDIT - I would post a descriptive image, but apparently I need reputation points. Sigh.
Please see here: http://i117.photobucket.com/albums/o63/Harry_Flashman/close_zpsfe6d3ea2.png
This is using points referencing an x and y,
data: [{x:108432,test:100,y:0}, {x:109802,test:100,y:51}, etc. ]
I want to do exactly as above, but without the gaps.
The only way I can see to have a non-linear gap-free axis is with categories, which I've used before on other line-type graphs, but never with a Scatter Plot.
If I use the x-axis type "category" with a category array instead, it only assigns one scatter value to each and the remainder to ascending numeric categories (i.e. it doesn't group them if I use the point "name" option).
xAxis: {
type: category,
categories: ['108432','109802','110240', etc. ]
}
with datapoints that look like this:
data: [{name:'108432',test:100,y:0}, {name:'109802',test:100,y:51}, etc. ]
Ends up like this. Each scatter point gets its own category.

Any help appreciated, this would be great if I could get it to work.
Thanks!

}]
});
});
Ok, fixed it via a workaround,
Essentially in Javascript I've added a position to the point arrays relating to which of the categories the point belongs to (generated via PHP, the categories are sorted ascending). Relevant bits are as follows:
xAxis: {
categories: ['r101831', 'r101849', 'r101850']
}
plotOptions: {
tooltip: {
headerFormat: '<b></b>',
pointFormat: '
<b>Test {point.test}</b><br/>
r{point.revision}<br/>
{point.y}% change<br/>
{series.name}'
}
}
series: [{
name: 'PRd',
data: [
{x:3,revision:101831,test:267,y:0},
{x:4,revision:101849,test:267,y:-1},
{x:5,revision:101850,test:267,y:-0}
]}
]
End result looks gorgeous, I love HighCharts.
