It offers an easy way of creating sophisticated and interactive charts and adding them to your website or web application.\r\n\r\nThe demo can be used as an example or a seed project. Local execution requires the following steps:\r\n\r\n-   Make sure that relevant version of [Node.js](https://nodejs.org/en/download/) is installed\r\n-   Open the project folder in a terminal:\r\n\r\n          npm install              # fetches dependencies\r\n          npm start                # builds an application and starts the development server\r\n\r\n-   The application is available at _http://localhost:8080_ in your browser, webpack-dev-server provides hot reload functionality.\r\n\n\n## Description\n\n_Also known as a Area Graph, Area Chart or Range Area Chart_\r\n\r\nThe example shows the basic usage of an Area Range series. The Range Area Chart is similar to the **_Area series_**, which is plotted by shading the area between a range of values ( high \u0026 low ) represented by two curves of data.\r\n\r\nRange charts are generally used to show variations (low \u0026 high) simultaneously in the given period. Typical visualization applications use this type of graph shows temperature, price etc.\r\n\r\nThe series uses two fill styles, which can be configured individually, the identical behavior is applicable for borders:\r\n\r\n-   the normal fill is used when High is greater than Low\r\n-   the reversed fill is used when Low is greater than High\r\n\r\n```javascript\r\n// Create a new ChartXY.\r\nconst chart = lightningChart().ChartXY()\r\n\r\n// Add an area series with bipolar direction using default X and Y axes.\r\nconst areaRange = chart.addAreaRangeSeries()\r\n```\r\n\r\nThe series accepts **_AreaPoint_** type of points either as an object in format `{ position: number, high: number, low: number }`,\r\n\r\n```javascript\r\nseries.add({ position: 20, high: 45, low: -20 })\r\n```\r\n\r\nor via a factory that should be additionally imported.\r\n\r\n```javascript\r\nseries.add(AreaPoint(20, 45, -20))\r\n```\r\n\r\nAny number of points can be added with a single call.\r\n\r\n```javascript\r\n// Single point.\r\nseries.add({ position: 20, high: 45, low: -20 })\r\n\r\n// Multiple points at once.\r\nseries.add([\r\n    { position: 20, high: 45, low: -20 },\r\n    { position: 40, high: 95, low: 10 },\r\n    { position: 60, high: 25, low: 60 },\r\n])\r\n```\r\n\n\n## API Links\n\n* [XY cartesian chart]\n* [Area point]\n* [Area Range series]\n\n\n## Support\n\nIf you notice an error in the example code, please open an issue on [GitHub][0] repository of the entire example.\r\n\r\nOfficial [API documentation][1] can be found on [LightningChart][2] website.\r\n\r\nIf the docs and other materials do not solve your problem as well as implementation help is needed, ask on [StackOverflow][3] (tagged lightningchart).\r\n\r\nIf you think you found a bug in the LightningChart JavaScript library, please contact sales@lightningchart.com.\r\n\r\nDirect developer email support can be purchased through a [Support Plan][4] or by contacting sales@lightningchart.com.\r\n\r\n[0]: https://github.com/Arction/\r\n[1]: https://lightningchart.com/lightningchart-js-api-documentation/\r\n[2]: https://lightningchart.com\r\n[3]: https://stackoverflow.com/questions/tagged/lightningchart\r\n[4]: https://lightningchart.com/support-services/\r\n\n© LightningChart Ltd 2009-2022.
