Demos | Documentation | Discord community | Reddit

TradingView Lightweight Charts™ are one of the smallest and fastest financial HTML5 charts.

The Lightweight Charts™ library is the best choice for you if you want to display financial data as an interactive chart on your web page without affecting your web page loading speed and performance.

It is the best choice for you if you want to replace static image charts with interactive ones. The size of the library is close to static images but if you have dozens of image charts on a web page then using this library can make the size of your web page smaller.

Installing

es6 via npm

npm install lightweight-charts
import { createChart } from 'lightweight-charts';

const chart = createChart(document.body, { width: 400, height: 300 });
const lineSeries = chart.addLineSeries();
lineSeries.setData([
    { time: '2019-04-11', value: 80.01 },
    { time: '2019-04-12', value: 96.63 },
    { time: '2019-04-13', value: 76.64 },
    { time: '2019-04-14', value: 81.89 },
    { time: '2019-04-15', value: 74.43 },
    { time: '2019-04-16', value: 80.01 },
    { time: '2019-04-17', value: 96.63 },
    { time: '2019-04-18', value: 76.64 },
    { time: '2019-04-19', value: 81.89 },
    { time: '2019-04-20', value: 74.43 },
]);

CDN

You can use unpkg:

https://unpkg.com/lightweight-charts/dist/lightweight-charts.standalone.production.js

The standalone version creates window.LightweightCharts object with all exports from esm version:

const chart = LightweightCharts.createChart(document.body, { width: 400, height: 300 });
const lineSeries = chart.addLineSeries();
lineSeries.setData([
    { time: '2019-04-11', value: 80.01 },
    { time: '2019-04-12', value: 96.63 },
    { time: '2019-04-13', value: 76.64 },
    { time: '2019-04-14', value: 81.89 },
    { time: '2019-04-15', value: 74.43 },
    { time: '2019-04-16', value: 80.01 },
    { time: '2019-04-17', value: 96.63 },
    { time: '2019-04-18', value: 76.64 },
    { time: '2019-04-19', value: 81.89 },
    { time: '2019-04-20', value: 74.43 },
]);
