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 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}'
},

How to set up tooltip display on top of all elements? I need to assign coordinates so that the tooltip does not close the chart, but the top block closes the tooltip.

If you want to place a tooltip outside of a chart container, enable outside option:
tooltip: {
outside: true,
...
}
Live example: https://jsfiddle.net/BlackLabel/casug0Lk/
API Reference: https://api.highcharts.com/highcharts/tooltip.outside
You can also create more space in a chart for a tooltip by setting marginTop property:
chart: {
marginTop: 150
}

I have a line chart with multiple data. Here is the sample of my chart.
Normally legend data are automatically show/hide if I click that legend on chart.
But after I adding a function in legend like this,
legend: {
position: 'right',
item: {
onclick: function (d) {
console.log("onclick", d);
show(d); //when I click legend show some data
}
}
},
I don't get automatically show/hide if I click that legend on chart. But its not important for me.
Instead of this, I want to show only clicking legend data in chart. if I click data1 legend, I want to show only data1 line in chart and hide another data2,data3 and data4 line in chart.
But, I don't have any idea how to do this. I'm very appreciate for any suggestion.
Now, I can solve my problem. Here is the code.
legend: {
position: 'right',
item: {
onclick: function (d) {
console.log("onclick", d); //data1
show(d); //when I click legend show some data
chart.hide();
chart.show(d);
}
}
},
First, I use chart.hide(). This function will hide all data on chart.
After that, I use chart.show(d) and it can show only data of user click because I add user clicking legend as an argument.
Note: show(d) is not related with chart.show(d). Just a function
that I create for my need.
For those of you stumbling across this like I did while looking for a way to focus on a single series from a legend click (I'm used to a double-click doing this), it seems c3 added the ability to use alt-click to focus on a single legend item. See the commit here. It turns out this works in billboard.js as well, which is a fork of c3.
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
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
