The TOAST UI products can be installed by using the package manager or downloading the source directly. However, we highly recommend using the package manager.
The TOAST UI products are registered in npm package manager. Install by using the commands provided by a package manager. When using npm, be sure Node.js is installed in the environment.
$ npm install --save @toast-ui/chart # Latest version
$ npm install --save @toast-ui/chart@<version> # Specific version
The TOAST UI Chart is available over a CDN.
- You can use cdn as below.
<link rel="stylesheet" href="https://uicdn.toast.com/chart/latest/toastui-chart.min.css" />
<script src="https://uicdn.toast.com/chart/latest/toastui-chart.min.js"></script>
- Within the download you'll find the following directories
- uicdn.toast.com/
├─ chart/
│ ├─ latest
│ │ ├─ toastui-chart.js
│ │ ├─ toastui-chart.min.js
│ │ ├─ toastui-chart.css
│ │ ├─ toastui-chart.min.css
│ ├─ v4.0.0/
Add the container element where TOAST UI Chart will be created.
<div id="chart"></div>
The TOAST UI Chart can be used by creating an instance with the constructor function. To access the constructor function, import the module using one of the three following methods depending on your environment.
/* namespace */
const Chart = toastui.Chart;
/* CommonJS in Node.js */
const Chart = require('@toast-ui/chart');
/* ES6 in Node.js */
import Chart from '@toast-ui/chart';
import { BarChart } from '@toast-ui/chart';
In Webpack 4, when importing package modules, the parts that are defined in the module field have higher priority than the parts defined in the main field. To use the Webpack 4 with the require
syntax to import @toast-ui/chart
, the ESM file defined in the module
field will be loaded, and the file will be transpiled to be compatible with the require
syntax. In order to use the bundle file for UMD, the user must personally load and use the @toast-ui/chart/dist/toastui-chart.js
or @toast-ui/chart/dist/toastui-chart.min.js
.
const Chart = require('@toast-ui/chart/dist/toastui-chart.min.js'); // loading the bundle file for UMD
Webpack 5 supports the exports
field. The entry point can be determined by the exports
field defined in the package. Furthermore, the necessary chart can be loaded through a sub-path, as presented below.
const Chart = require('@toast-ui/chart'); // ./dist/toastui-chart.js
import { BarChart } from '@toast-ui/chart'; // ./dist/esm/index.js
import BarChart from '@toast-ui/chart/bar';
import ColumnChart from '@toast-ui/chart/column';
import LineChart from '@toast-ui/chart/line';
import AreaChart from '@toast-ui/chart/area';
import LineAreaChart from '@toast-ui/chart/lineArea';
import ColumnLineChart from '@toast-ui/chart/columnLine';
import BulletChart from '@toast-ui/chart/bullet';
import BoxPlotChart from '@toast-ui/chart/boxPlot';
import TreemapChart from '@toast-ui/chart/treemap';
import HeatmapChart from '@toast-ui/chart/heatmap';
import ScatterChart from '@toast-ui/chart/scatter';
import LineScatterChart from '@toast-ui/chart/lineScatter';
import BubbleChart from '@toast-ui/chart/bubble';
import PieChart from '@toast-ui/chart/pie';
import NestedPieChart from '@toast-ui/chart/nestedPie';
import RadarChart from '@toast-ui/chart/radar';
You need to add the CSS files needed for the Chart. Import CSS files in node environment, and add it to html file when using CDN.
- ES6 Modules
import '@toast-ui/chart/dist/toastui-chart.min.css';
- Common JS
require('@toast-ui/chart/dist/toastui-chart.min.css');
- CDN
<link rel="stylesheet" href="https://uicdn.toast.com/chart/latest/toastui-chart.min.css" />
Constructor function needs three parameters: el
, data
, options
- el: Wrapper HTML element that will contain the chart as a child.
- data: Numerical data the chart will be based on.
- options: Functional options including legend, alignment, and tooltip formatter.
const el = document.getElementById('chart');
const data = {
categories: ['Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec'],
series: [
{
name: 'Budget',
data: [5000, 3000, 5000, 7000, 6000, 4000, 1000],
},
{
name: 'Income',
data: [8000, 4000, 7000, 2000, 6000, 3000, 5000],
},
],
};
const options = {
chart: { width: 700, height: 400 },
};
const chart = Chart.barChart({ el, data, options });
// const chart = new BarChart({ el, data, options }); // Second way
