How to change fontSize for dataLabels? - javascript

I do not see in docs any mention how to adjust fontSize of dataLabels.
dataLabels do not have any mention about font size:
dataLabels: {
offset: 0,
minAngleToShowLabel: 10
},
It's not possible?
new Vue({
el: "#app",
data() {
return {
series: [4, 7, 3, 45, 32, 53],
options: {
expandOnClick: true,
dataLabels: {
minAngleToShowLabel: 50,
// offsetY: 1200,
style: { fontSize: '18px' } // this do not work!
},
chart: {
width: 480,
type: 'pie',
},
legend: {
// offsetX: 510,
fontSize: '16px',
height: 500,
width: 400,
horizontalAlign: 'right',
},
title: {
text: 'Some name',
style: {
fontSize: '20px',
},
},
labels: ["aa", "bb", "cc", "dd", "ee", "ff"],
responsive: [{
breakpoint: 480,
options: {
chart: {
width: 480
},
legend: {
position: 'right',
offsetY: 40,
fontSize: '16px',
},
}
}]
},
}
},
methods: {

components: {
VueApexCharts
}
})

You can find a pretty good summary of your options here on this page: https://apexcharts.com/docs/options/datalabels/
style: {
fontSize: '14px',
fontFamily: 'Helvetica, Arial, sans-serif',
fontWeight: 'bold',
colors: undefined
},

You can simply provide styling in CSS class.
.apexcharts-pie-label{
font-size:25px;

Now the blue line is equal to the height of the graph
Please tell me how to make the line start from the marker to the bottom line x
I will be glad for any help
I do not think you can do this with simple configuration. However, since ApexCharts is based on SVG, you can manipulate the DOM yourself quite easily.
As I said previously in other answers, because I have already used this technique several times, what I am going to show you is more experimental than official.
It works, though.
In your case, the idea is to put some code in the mouseMove event callback. The use of a MutationObserver is recommended to watch for changes in the DOM. When a marker (which is a circle) is hovered, its r, cx and cy attributes are updated. In particular, cy is the most interesting because it gives us the vertical position of the active marker. r is also useful to adjust the offset of crosshairs.
Here is the main part of the code:
chart: {
// ...
events: {
mouseMove: () => {
let crosshairs = document.querySelector('.apexcharts-xcrosshairs'),
marker = document.querySelector('.apexcharts-marker');
let settings = { attributes: true },
observer = new MutationObserver(() => {
crosshairs.setAttribute('y1', `${marker.cy.baseVal.value + marker.r.baseVal.value + 1}`);
});
observer.observe(marker, settings);
}
}
},
Here is the full code:
const data = [45, 52, 78, 45, 69, 23, 30, 45, 52, 88];
const dataXCategories = ["10.12", "11.12", "12.12", "13.12", "14.12", "15.12", "16.12", "17.12", "18.12", "19.12"];
new ApexCharts(chart, {

mouseMove: () => {
let crosshairs = document.querySelector('.apexcharts-xcrosshairs'),

let settings = { attributes: true },
observer = new MutationObserver(() => {
crosshairs.setAttribute('y1', `${marker.cy.baseVal.value + marker.r.baseVal.value + 1}`);
});
observer.observe(marker, settings);

When there is a plotband and a plotline emerging from yAxis how to set a particular width for plotband only in highchart

The plotline should spread across the graph but the plot band should of smaller width.
1) Initially without width being set.
2) When y axis width is set to 20
3) I want something like this where both the plot band and the plotline co exists
this is the fiddle code link to what I have tried so far.
Can someone please help me out thank you very much in advance.

Highcharts - chartanimation step by step

Is it possible to render charts and animate them step by step?
Right now I got three area-datasets in my chart which I need to animate step by step. Dataset/area 1 shall start and after this is finished, Dataset/area 2 need to start and then 3.
I cannot find an option for that, is this even possible with Highcharts?
Right now the Animation goes from left,bottom to right,up - is there an option for an animation direction? I want to start the animation from the full width (fully expanded on the xAxis) to go upwarts the yAxis.
My Options:
var $chart = $('#chart');
var chart = new Highcharts.Chart({
chart: {

You can use series.afterAnimate event in which you can fire animation for another series.
In your first series set afterAnimate like this:
events: {
afterAnimate: function () {
this.chart.get('1').update({
visible: true,
animation: {
duration: 2000
},
events: {
afterAnimate: function () {
this.chart.get('2').update({
visible: true,
animation: {
duration: 3000
}
})
}
}
})
}
},
For the other series, initially you can disable animation or/and set their visibility to false:
series: [{
name: '2',
id: '2',
legendIndex: 2,
color: '#83bd3f',
animation: {
duration: 0
},
visible: false,
To change the direction of the animation you need to wrap series.animate
method and change how the clipping rect is animated.
(function(H) {
H.wrap(H.seriesTypes.area.prototype, 'animate', function(proceed, init) {
var series = this,
chart = series.chart,
clipRect,
animation = H.animObject(series.options.animation),
sharedClipKey,
newH;
if (init) {
return proceed.apply(this, Array.prototype.slice.call(arguments, 1));
} else {
sharedClipKey = this.sharedClipKey;
clipRect = chart[sharedClipKey];
if (clipRect) {
clipRect.attr({
y: chart.plotSizeY,
height: 0,
width: chart.plotSizeX
}).animate({
y: 0,
height: chart.plotSizeY
}, animation);
}
if (chart[sharedClipKey + 'm']) {
chart[sharedClipKey + 'm'].attr({
y: chart.plotSizeY,
height: 0,
width: chart.plotSizeX + 99
}).animate({
y: 0,
height: chart.plotSizeY
}, animation);
}
// Delete this function to allow it only once
series.animate = null;
}
});

Style doesn't seem to be updated. Please help. Thanks
Your click event is not fired because of the difference in id.
Remove hash from button's id: <button id='update'> Update </button>
Then you can update axis via axis.update()
$('#update').click(function() {
chart.colorAxis[0].update({
labels: {
style: {
fontSize: '20px'
}
}
})
});

Highcharts gauge not rendering text

I am trying to create a gauge using Highcharts.
