# JavaScript Stacked Bar Chart
This demo application belongs to the set of examples for LightningChart JS, data visualization library for JavaScript.
LightningChart JS is entirely GPU accelerated and performance optimized charting library for presenting massive amounts of data. It offers an easy way of creating sophisticated and interactive charts and adding them to your website or web application.
The demo can be used as an example or a seed project. Local execution requires the following steps:
- Make sure that relevant version of [Node.js](https://nodejs.org/en/download/) is installed
- Open the project folder in a terminal:
npm install # fetches dependencies
npm start # builds an application and starts the development server
- The application is available at _http://localhost:8080_ in your browser, webpack-dev-server provides hot reload functionality.
## Description
This example shows creation of a Stacked Bars Chart.
The stacked bar chart (aka stacked bar graph) extends the standard bar chart from looking at numeric values across one categorical variable to two. Each bar in a standard bar chart is divided into a number of sub-bars stacked end to end, each one corresponding to a level of the second categorical variable.
Here's the creation of a Stacked Bar Chart with LightningChart JS.
```javascript
// Create Chart.
const barChart = lightningChart().BarChart()
// Add categories and subCategory & values.
barChart.setDataStacked(
['category1', 'category2', 'category2'],
[
{ subCategory: 'subCategory 1', values: [1, 51, 43] },
{ subCategory: 'subCategory 2', values: [66, 18, 1] },
{ subCategory: 'subCategory 3', values: [1, 7, 20] },
],
)
```
