I want to customize the label of the tooltip on chart js. I just want to show as bold the value of portfolio (+2,5%).
I found this example:
https://jsfiddle.net/nosensus/hhcyhjf9/
When i apply it, my tooltip is always on the left bottom, not on the chart.
How can fix it? I am using Chart.js 2.9.4 version and developing with Angular.
tooltip of the chart should be like this
Put the text you would like to be bold between these tags:
<strong>...</strong>
Like below :
tooltip: {
trigger: 'item',
formatter: '<strong>{a}</strong> <br/> {b}:{c}'
},

I have some charts with their respective categories and those categories have a representative icon, There is way to add an icon/image over the chart in title section or nearby?
I tried to use this code on the title definition but it didn't work, only works when adding images to top of chart on every column.
useHTML: true,
formatter: function () {
return '<img src="./img/statics.png"><img>';
}
i tried to put the image code on the div but looks like the code gets overridden by highcharts.
Use below function after chart
chart.setTitle({
useHTML: true,
text: '<img src="./img/statics.png"/>';
});
See the fiddle here , I used a website's logo in title.
I was looking at this highchart stacked column - Highchart Demo
and I'm wondering if it's possible to have a tooltip when you mouse over the total stacked label.
stackLabels: {
enabled: true,
style: {
fontWeight: 'bold'
}
}
I wanted to achieve something like this - See Image here.
Note: I wanted to have a tooltip on mouseover the Total Stacked Label not on the column series.
You can use a custom-events plugin which allows to cache events on stackLabels.
I have implemented the chartjs. And used piechart. Currently tooltip shows on hover. Is there any way to show the tooltip by default?
As I can understand, you want to always show a tooltip for a given data segment
You can use following code snippet:
var pieChart = $("#chartContainer").dxPieChart({
dataSource: data,
series: {}
}).dxPieChart("instance");
pieChart.getSeries().getPointByArg("Second").showTooltip();
See working sample here
And demo here
I'm using HighStock.js library and I'm trying to display the flags and their tooltips.
Everything works well, except the tooltip box is too wide that it goes outside of the chart area.
How do I format the box so that its width is set?
I tried the following
plotOptions:
flags:
useHTML:true
tooltip:
followPointer:true
pointFormat:"<div style='width:200px;'>{point.text}</div>"
But nothing changes.
You can set more CSS styles like white-space: pre-wrap, take a look: http://jsfiddle.net/9Pxka/6/
We'd like to add some textual annotation to the charts we create using Highcharts.js.
Ideally we would like to show the annotation in a pop-up window when you mouse over the chart title or a question-mark next to the chart title.
For example:
<b>Chart Title</b>
<sup>
?</sup>
However, when I pass the above html as the Highcharts chart title text attribute, Highcharts does not display it properly, it in fact displays the html text.
Is it possible to make this work using Highcharts interface? If so, how?
Any other suggestions would be appreciated.
Thanks.
The following works:
title: {
useHTML: true,
text: 'This is <b>bold</b>'
}
The useHtml property doesn't seem to be in the documentation that I can see but it seems to work for me and it also works on labels
