A modern JavaScript charting library to build interactive charts and visualizations with simple API.

Why another Chart Library?

It's a long read, so I have written a detailed explanation on this medium post

Download and Installation

Installing via npm

Direct <script> include

<script src="https://unpkg.com/apexcharts/dist/apexcharts.min.js"></script>

Usage

Creating your first chart

To create a basic bar chart with minimal configuration, write as follows:

var options = {
  chart: {
    type: 'bar'
  },
  series: [{
    name: 'sales',
    data: [30, 40, 35, 50, 49, 60, 70, 91, 125]
  }],
  xaxis: {
    categories: [1991, 1992, 1993, 1994, 1995, 1996, 1997, 1998, 1999]
  }
}

var chart = new ApexCharts(document.querySelector("#chart"), options);
chart.render();

This will render the following chart

A little more than the basic

You can create a combination of different charts, sync them and give your desired look with unlimited possibilities. Below is an example of synchronized charts with github style.

Some interactivity

Zoom, Pan, Scroll through data. Make selections and load other charts using those selections. An example showing some interactivity

Dynamic Data Updation

Another approach to Drill down charts where one selection updates the data of other charts. An example of loading dynamic series into charts is shown below

Annotations

Annotations allows you to write custom text on specific values or on axes values. Valuable to expand the visual appeal of your chart and make it more informative.

Mixed Charts

You can combine more than one chart type to create a combo/mixed chart. Possible combinations can be line/area/column together in a single chart. Each chart-type can have it's own y-axis.

Heatmaps

Use Heatmaps to represent data through colors and shades. Frequently used with bigger data collections, they are valuable for recognizing patterns and area of focus.

Gauges

The tiny gauges are an important part of a dashboard and are useful in displaying single series data. A demo of these gauges:

Sparklines

Utilize sparklines to indicate trends in data, for example, occasional increments or declines, monetary cycles, or to feature most extreme and least values:

What's included

The download bundle includes the following files and directories providing a minified single file in the dist folder. Every asset including icon/css is bundled in the js itself to avoid loading multiple files.

apexcharts/
├── dist/
│   └── apexcharts.min.js
├── src/
│   ├── assets/
│   ├── charts/
│   ├── modules/
│   ├── utils/
│   └── apexcharts.js
└── samples/

Development

Install dependencies and run project

npm install
npm run start

This will start the webpack watch and any changes you make to src folder will auto-compile and output will be produced in the dist folder.

Minifying the src

npm run build
