# JavaScript Stacked Mountains Chart

![JavaScript Stacked Mountains Chart](stackedMountains-darkGold.png)

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

_Also known as Stacked Area Graph or Stacked Areas_

The stacked charts are a popular visual aid used for categorizing and comparing the parts of a whole using different colors to distinguish the categories.

This chart is created with custom stacking logic by using **_Area_** and **_AreaRange_** series and position each next data segment on top of the previous. Relying on characteristics and use cases of mountain series mentioned in previous examples, area is drawn on a Cartesian coordinate system and represents the quantitative data. Thus, in the example, the first data segment starts from a zero baseline and each next category would use the magnitude of previous segment as a low starting point.

```javascript
// Create one Area series to be the base.
const areaFirst = chart.addAreaSeries()

// Create the next AreaRange series to be stacked on top of previous.
const areaNext1 = chart.addAreaRangeSeries()
const areaNext2 = chart.addAreaRangeSeries()
```
