Tutorial: Getting Started with ApexCharts
Introduction
ApexCharts is a modern charting library that helps developers create interactive and responsive charts in web applications. It supports a wide range of chart types, including line charts, bar charts, pie charts, and more. ApexCharts is easy to integrate with popular frameworks like React, Vue, Angular, and even plain JavaScript, making it a versatile tool for data visualization.
In this tutorial, we’ll cover how to set up ApexCharts, create various types of charts, customize them, and integrate them into a web project.
Prerequisites
Before starting, ensure you have the following:
- Basic knowledge of HTML, CSS, and JavaScript.
- A text editor or an integrated development environment (IDE) like Visual Studio Code.
- A web browser for testing.
Step 1: Setting Up ApexCharts
Method 1: Using a CDN
The easiest way to start using ApexCharts is by including it directly in your HTML file using a CDN.
- Create an HTML file (e.g.,
index.html) and add the following code:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>ApexCharts Example</title>
<!-- Include ApexCharts CDN -->
<script src="https://cdn.jsdelivr.net/npm/apexcharts"></script>
</head>
<body>
<div id="chart"></div>
<script src="script.js"></script>
</body>
</html>
Method 2: Installing via npm (for frameworks)
If you’re working with a JavaScript framework like React or Vue, you can install ApexCharts via npm.
- Install ApexCharts:
npm install apexcharts
- Import ApexCharts into your JavaScript file:
import ApexCharts from 'apexcharts';
Step 2: Creating Your First Chart
Let’s start by creating a basic line chart.
- Create a JavaScript file (e.g.,
script.js) and add the following code:
var options = {
chart: {
type: 'line'
},
series: [{
name: 'Sales',
data: [10, 20, 15, 30, 25, 40, 35]
}],
xaxis: {
categories: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul']
}
}
var chart = new ApexCharts(document.querySelector("#chart"), options);
chart.render();
- Run the HTML file (
index.html) in your browser, and you should see a simple line chart.
Step 3: Customizing the Chart
ApexCharts offers a wide range of customization options, from changing colors to adding tooltips and legends.
Customizing Colors
You can customize the colors of the chart using the colors option.
var options = {
chart: {
type: 'line'
},
series: [{
name: 'Sales',
data: [10, 20, 15, 30, 25, 40, 35]
}],
xaxis: {
categories: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul']
},
colors: ['#FF5733'] // Custom line color
}
var chart = new ApexCharts(document.querySelector("#chart"), options);
chart.render();
Adding a Title
You can add a title to your chart for better context.
var options = {
chart: {
type: 'line'
},
series: [{
name: 'Sales',
data: [10, 20, 15, 30, 25, 40, 35]
}],
xaxis: {
categories: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul']
},
title: {
text: 'Monthly Sales Data',
align: 'center'
}
}
var chart = new ApexCharts(document.querySelector("#chart"), options);
chart.render();
Adding Tooltips and Legends
Tooltips and legends can help users understand the data more easily.
var options = {
chart: {
type: 'line'
},
series: [{
name: 'Sales',
data: [10, 20, 15, 30, 25, 40, 35]
}],
xaxis: {
categories: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul']
},
title: {
text: 'Monthly Sales Data',
align: 'center'
},
tooltip: {
enabled: true,
theme: 'dark'
},
legend: {
position: 'top',
horizontalAlign: 'right'
}
}
var chart = new ApexCharts(document.querySelector("#chart"), options);
chart.render();
Step 4: Creating Different Types of Charts
ApexCharts supports various chart types. Let’s explore some of them.
Bar Chart
var options = {
chart: {
type: 'bar'
},
series: [{
name: 'Revenue',
data: [30, 40, 45, 50, 49, 60, 70, 91]
}],
xaxis: {
categories: ['2015', '2016', '2017', '2018', '2019', '2020', '2021', '2022']
},
title: {
text: 'Annual Revenue',
align: 'center'
}
}
var chart = new ApexCharts(document.querySelector("#chart"), options);
chart.render();
Pie Chart
var options = {
chart: {
type: 'pie'
},
series: [44, 55, 13, 43, 22],
labels: ['Apples', 'Oranges', 'Bananas', 'Berries', 'Mangoes'],
title: {
text: 'Fruit Consumption',
align: 'center'
}
}
var chart = new ApexCharts(document.querySelector("#chart"), options);
chart.render();
Area Chart
var options = {
chart: {
type: 'area'
},
series: [{
name: 'Visitors',
data: [31, 40, 28, 51, 42, 109, 100]
}],
xaxis: {
categories: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul']
},
title: {
text: 'Website Visitors',
align: 'center'
}
}
var chart = new ApexCharts(document.querySelector("#chart"), options);
chart.render();
Step 5: Responsive Charts
ApexCharts are responsive by default, but you can further customize how charts behave on different screen sizes.
var options = {
chart: {
type: 'line',
height: '100%',
width: '100%'
},
series: [{
name: 'Sales',
data: [10, 20, 15, 30, 25, 40, 35]
}],
xaxis: {
categories: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul']
},
responsive: [{
breakpoint: 480,
options: {
chart: {
width: '100%'
},
legend: {
position: 'bottom'
}
}
}]
}
var chart = new ApexCharts(document.querySelector("#chart"), options);
chart.render();
Step 6: Exporting and Downloading Charts
ApexCharts provides options to export your charts as images or CSV files, making it easy to share your data.
var options = {
chart: {
type: 'line',
toolbar: {
show: true,
tools: {
download: true
}
}
},
series: [{
name: 'Sales',
data: [10, 20, 15, 30, 25, 40, 35]
}],
xaxis: {
categories: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul']
},
title: {
text: 'Sales Data with Export Option',
align: 'center'
}
}
var chart = new ApexCharts(document.querySelector("#chart"), options);
chart.render();
Step 7: Integrating ApexCharts with Frameworks
ApexCharts can be easily integrated with popular JavaScript frameworks like React, Vue, and Angular.
React Example
- Install ApexCharts and the React wrapper:
npm install apexcharts react-apexcharts
- Create a chart component in your React project:
import React from 'react';
import Chart from 'react-apexcharts';
class MyChart extends React.Component {
constructor(props) {
super(props);
this.state = {
options: {
chart: {
type: 'line'
},
xaxis: {
categories: ['Jan', 'Feb', 'Mar', 'Apr', 'May
', 'Jun', 'Jul']
}
},
series: [{
name: 'Sales',
data: [10, 20, 15, 30, 25, 40, 35]
}]
}
}
render() {
return (
<div>
<Chart options={this.state.options} series={this.state.series} type="line" />
</div>
);
}
}
export default MyChart;
- Use the component in your application:
import React from 'react';
import MyChart from './MyChart';
function App() {
return (
<div className="App">
<MyChart />
</div>
);
}
export default App;
