Vue 3 component for ApexCharts to build interactive visualizations in vue.
npm install --save apexcharts
npm install --save vue3-apexchartsIf you're looking for Vue 2.x.x compatibile component, check-out vue-apexcharts
import VueApexCharts from "vue3-apexcharts";
const app = createApp(App);
app.use(VueApexCharts);
// The app.use(VueApexCharts) will make <apexchart> component available everywhere.OR
// you can import in a particular component and register the component like below
import VueApexCharts from "vue3-apexcharts";
export default {
components: {
apexchart: VueApexCharts,
},
};To provide a $apexcharts reference inside Vue instance
import ApexCharts from "apexcharts";
app.config.globalProperties.$apexcharts = ApexCharts;
// Add this when into a TypeScript codebase
declare module "@vue/runtime-core" {
interface ComponentCustomProperties {
$apexcharts: typeof ApexCharts;
}
}To create a basic bar chart with minimal configuration, write as follows:
<template>
<div>
<apexchart
width="500"
type="bar"
:options="chartOptions"
:series="series"
></apexchart>
</div>
</template>export default {
data: function () {
return {
chartOptions: {
chart: {
id: "vuechart-example",
},
xaxis: {
categories: [1991, 1992, 1993, 1994, 1995, 1996, 1997, 1998],
},
},
series: [
{
name: "series-1",
data: [30, 40, 35, 50, 49, 60, 70, 91],
},
],
};
},
};This will render the following chart
Simple! Just change the series or any option and it will automatically re-render the chart.
Click on the below example to see this in action
<template>
<div class="app">
<apexchart
width="550"
type="bar"
:options="chartOptions"
:series="series"
></apexchart>
<div>
<button @click="updateChart">Update!</button>
</div>
</div>
</template>export default {
data: function () {
return {
chartOptions: {
chart: {
id: "vuechart-example",
},
xaxis: {
categories: [1991, 1992, 1993, 1994, 1995, 1996, 1997, 1998],
},
},
series: [
{
name: "series-1",
data: [30, 40, 45, 50, 49, 60, 70, 81],
},
],
};
},
methods: {
updateChart() {
const max = 90;
const min = 20;
const newData = this.series[0].data.map(() => {
return Math.floor(Math.random() * (max - min + 1)) + min;
});
const colors = ["#008FFB", "#00E396", "#FEB019", "#FF4560", "#775DD0"];
// Make sure to update the whole options config and not just a single property to allow the Vue watch catch the change.
this.chartOptions = {
colors: [colors[Math.floor(Math.random() * colors.length)]],
};
// In the same way, update the series option
this.series = [
{
data: newData,
},
];
},
},
}; Important: While updating the options, make sure to update the outermost property even when you need to update the nested property.
✅ Do this
this.chartOptions = {
...this.chartOptions,
...{
xaxis: {
labels: {
style: {
colors: ["red"],
},
},
},
},
};❌ Not this
this.chartOptions.xaxis = {
labels: {
style: {
colors: ['red']
}
}
}}| Prop | Type | Description |
|---|---|---|
| series* | Array | The series is an array which accepts an object in the following format. To know more about the format of dataSeries, checkout Series docs on the website. |
| type* | String | line, area, bar, pie, donut, scatter, bubble, heatmap, radialBar, candlestick |
| width | Number/String | Possible values for width can be 100% or 400px or 400 |
| height | Number/String | Possible values for height can be 100% or 300px or 300 |
| options | Object | The configuration object, see options on API (Reference) |
You don't actually need to call updateSeries() or updateOptions() manually. Changing the props will automatically update the chart. You only need to call these methods to update the chart forcefully.
| Method | Description |
|---|---|
| updateSeries | Allows you to update the series array overriding the existing one |
| updateOptions | Allows you to update the configuration object |
| toggleSeries | Allows you to toggle the visibility of series programatically. Useful when you have custom legend. |
| appendData | Allows you to append new data to the series array. |
| addXaxisAnnotation | Draw x-axis annotations after chart is rendered. |
| addYaxisAnnotation | Draw y-axis annotations after chart is rendered. |
| addPointAnnotation | Draw point (xy) annotations after chart is rendered. |
Sometimes, you may want to call methods of the core ApexCharts library from some other place, and you can do so on window.ApexCharts global variable directly. You need to target the chart by chart.id while calling this method
Example
window.ApexCharts.exec("vuechart-example", "updateSeries", [
{
data: [40, 55, 65, 11, 23, 44, 54, 33],
},
]);In the above method, vuechart-example is the ID of chart, updateSeries is the name of the method you want to call and the third parameter is the new Series you want to update.
More info on the .exec() method can be found here
All other methods of ApexCharts can be called the same way.
