I'm creating new variablepie highchart js. In that graph how to reduce space(height) of tooltip box. I need to reduce top and bottom space inside the tooltip box.
URL: https://jsfiddle.net/gh/get/library/pure/highcharts/highcharts/tree/master/samples/highcharts/demo/variable-radius-pie
tooltip: {
headerFormat: '',
pointFormat: ' <b>COMPANY</b><br/>' +
'Match Percent: <b>{point.y}</b><br/>' +
'Score Weight: <b>{point.z}</b><br/>',
valueSuffix: ' %',
useHTML: true,
outside: true,
style: {
padding: 0
},
followPointer:true
},
You need to set the padding directly in a tooltip configuration object:
tooltip: {
padding: 0,
...
}
Live demo: https://jsfiddle.net/BlackLabel/eom8tqns/
API Reference: https://api.highcharts.com/highcharts/tooltip.padding
But the main thing is, it will only support numbers not px values

I'm trying to make the bubble labels ('USA', 'Canada', 'Mexico', 'Brazil') bigger.
I've looked at the series API for packedbubble but haven't found a way to increase the size of the text in the bubbles through options https://api.highcharts.com/highcharts/series.packedbubble
The only way I've found to do this is to write css, which doesn't handle scaling, doesn't center up, and generally seems hacky...
.highcharts-data-label text tspan {
font-size: 24px
}
Whats the correct way to increase the size of these labels?
Looks like you can set fontSize inside plotOptions.packedbubble.dataLabels
plotOptions: {
packedbubble: {
minSize: '20%',
maxSize: '100%',
zMin: 0,
zMax: 1000,
layoutAlgorithm: {
gravitationalConstant: 0.05,
splitSeries: true,
seriesInteraction: false,
dragBetweenSeries: true,
parentNodeLimit: true
},
dataLabels: {
enabled: true,
format: '{point.name}',
filter: {
property: 'y',
operator: '>',
value: 250
},
style: {
color: 'black',
textOutline: 'none',
fontWeight: 'normal',
fontSize: '24px'
}
}
}
},
Found a couple of posts that came close to solving this. I'm loading a chart into a widget and it's not filling it, instead it's centered and extended past the widget - about only 1/3 of the pie chart shows for example.
I found the resize options for gridster and it gets me almost there... the same problem exists when I load the page, but when I resize the widget the chart fills it in perfectly.
I've tried aligning the chart, removing width and height settings, addeing resize and stop elements to gridsters..
var gridster = null;
$(document).ready(function () {
gridster = $(".gridster ul").gridster({
widget_base_dimensions: ['auto', 140],
autogenerate_stylesheet: true,
min_cols: 1,
max_cols: 6,
widget_margins: [5, 5],
resize: {
enabled: true,
resize: function (e, ui, $widget) {
Highcharts.charts[0].reflow(); // reflow the first chart...
},
stop: function(e, ui, $widget) {
Highcharts.charts[0].reflow(); // reflow the first chart...
}
}
}).data('gridster');
$('.gridster ul').css({'padding': '0'});
});
Highcharts.chart('container', {
chart: {
type: 'pie'
},
title: {
text: 'User data',
style: {"fontSize": "15px" , "color":"red"},
},
subtitle: {
text: 'Source: Click the slices to view categories.'
},
plotOptions: {
pie: {
showInLegend: false,
dataLabels: {
formatter: function(){
console.log(this);
if (this.percentage > 5)
return this.key + ': ' + this.y;
else
this.point.visible = false;
return '';
}
}
},
series: {
dataLabels: {
enabled: true,
}
}
},
tooltip: {
headerFormat: '<span style="font-size:11px">{series.name}</span><br>',
pointFormat: '{series.name}: <b>{point.percentage:.1f}%</b>'
},
when page loads the pie chart is sized to fit into the gridster widget.
Add one div wrapper around widget and add class which having height and width of that widget. It will render your highchart graph in that wrapper only.
<div class="size-1x1">
Render your graph code here
</div>
CSS:
.size-1x1 {
height:100px;
width: 120px;
}
Looking to work with the below chart, but cannot get to change the title color to white and the axis and axis numbers to grey (or white). This should go above a dark background. Does anybody knows how to change the title color with echarts ?
<script type="text/javascript">
// based on prepared DOM, initialize echarts instance
var myChart = echarts.init(document.getElementById('main'));
// specify chart configuration item and data
var option = {
title: {
text: 'Total memebers of the club',
fontColor: 'white',
display: true,
position: 'bottom'
},
tooltip: {},
legend: {
data: ['Total member']
},
xAxis: {
data: ["11/2018", "12/2018", "01/2019", "02/2019", "03/2019", "04/2019"]
},
yAxis: {},
series: [{
itemStyle: {normal: {color: 'white'}},
name: 'Total',
type: 'bar',
data: [5, 384, 612, 2344, 4670, 9372]
}]
};
// use configuration item and data specified to show chart
myChart.setOption(option);
</script>
Give this a try. Add it under 'text:' like:
text: 'Total memebers of the club',
textStyle: {
color: '#ed2d2e'
}
I would like to make tooltip in Highstock styled differently(not just style of content, but style for tooltip itself. For example, different padding, shadow, border radious etc) when hovering over flag series and line serieses. However, it looks like these properties needs to be configured in the tooltip configuration object. Not sure if it can be dynamically changed.
Like in this jsbin:

What's the better way to give 'Summer arrives' tooltip different style than other shared tooltips?
Your approach is correct. In the formatter callback wrap the text in the html tags and style it using css, inline or by class name, depending if it is a flag or line series. Make sure you set useHTML to true.
tooltip: {
useHTML:true,
borderWidth: 0,
headerFormat: '',
shared: true,
formatter: function(){
if (!!this.points) {
return this.points
.reduce(
function(prev, cur) {
return prev +
'<br>' + cur.series.name + ': '+ cur.y;
}, '');
}
return "<div style='border:5px solid black; padding: 20px'>Summer arrives!</div>";
},
padding: 0
}
example: https://jsfiddle.net/hpeq7Lbe/1/
Actually, you can set different options for flag's and line's tooltip, but not all the options are supported, e.g. padding or border width will not work - they have to be set in the tooltip's global options.
plotOptions: {
line: {
tooltip: {
pointFormat: 'line',
borderWidth: 10, // not supported
padding: 10 // not supported
}
},
flags: {
tooltip: {
pointFormat: 'flags',
borderWidth: 1, //not supported
padding: 1 // not supported
}
}
}

Is there way to set the label of an Bar Chart to 50% of the charts width? I've tried this but it does not work:
xAxis: {
categories: [],
labels: {
formatter: function() {
var text = this.value;
return '<div class="js-ellipse" style="width:100%; overflow:hidden; text-overflow: ellipsis" title="' + text + '">' + text + '</div>';
},
style: {
width: '50%'
},
useHTML: true
}
},
So goal is to have labels on the left side of the bar chart that are 50% of the width of the whole chart container.
You have an option for that in the plotOptions :
plotOptions: {
bar: {
dataLabels: {
enabled: true,
inside: true
// ^^^^^^^^^^^^
}
}
},
The property inside :
For points with an extent, like columns, whether to align the data label inside the box or to the actual value point. Defaults to false in most cases, true in stacked columns.
And an example forked from the official documentation : http://jsfiddle.net/XXB9k/
EDIT :
There is another option to center the x labels (I don't know witch labels your are talking about), but there is a solution not far away from your code :
xAxis: {
...
labels: {
enabled: true,
x: this.width / 2,
}
}
An example : http://jsfiddle.net/QMPkh/
FINAL EDIT :
In fact you can simply use the width of the chart in the label formatter :
labels: {
enabled: true,
formatter: function() {
return '<div style="width:' + (this.axis.width/2) +'px">'+this.value+'</div>';
},
useHTML: true
}
An example to show the result : http://jsfiddle.net/QMPkh/2/
Unfortunately width in percent is not supported, only in pixels.
