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\nThis example showcases a simple Polar Chart with five Line Series.\r\n\r\nPolar Charts are used for visualizing data relationships in terms of radiuses and angles.\r\n\r\n## Polar coordinate system and PolarLineSeries\r\n\r\n```typescript\r\n{\r\n    // Data point angle as degrees [0, 360].\r\n    angle: 0,\r\n    // Data point position on the *Amplitude Axis*. Determines its location between the Charts origin and outer edge.\r\n    amplitude: 50\r\n}\r\n```\r\n\r\n_PolarLineSeries_ connects a list of such _PolarPoints_ with a continuous line.\r\n\r\n[//]: # 'IMPORTANT: The assets will not show before README.md is built - relative path is different!'\r\n\r\n![Two Polar Line Series](./assets/polarLineSeries.png)\r\n\r\n## PolarRadialAxis\r\n\r\nThe coordinate system can be rotated with methods of \\*PolarRadialAxis\\*\\*.\r\n\r\n```typescript\r\n// Configure Polar Radial Axis.\r\nconst radialAxis = polar\r\n    .getRadialAxis()\r\n    // 0 = North\r\n    .setRotation(90)\r\n    // Clockwise direction.\r\n    .setInverted(true)\r\n```\r\n\r\n## PolarAmplitudeAxis\r\n\r\nSimilarly, the visible range of amplitude values can be configured with methods of _PolarAmplitudeAxis_. The default configuration is to fit\r\n\r\n```typescript\r\nconst amplitudeAxis = polar\r\n    .getAmplitudeAxis()\r\n    // Set amplitude interval explicitly.\r\n    // [-39 dB, 0 dB]\r\n    .setInterval({ start: -39, end: 0, stopAxisAfter: false })\r\n    .setTitle('Sensitivity (dB)')\r\n```\r\n\n\n## API Links\n\n* [Polar chart]\n* [Polar line series]\n* [Polar radial axis]\n* [Polar amplitude axis]\n* [Polar point]\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 2009-2025.
