+# Parallel Coordinate Chart with Value Thresholds
+
+![Parallel Coordinate Chart with Value Thresholds](parallelCoordChartThresholds-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
+
+A common use case is to display value thresholds on different axes.
+E.g. which value range is _bad_ and which is _good_.
+
+This example shows how this can be done by styling the Axis line style with a `PalettedFill`.
+
+## API Links
+
+
+
+## Support
+
+If you notice an error in the example code, please open an issue on [GitHub][0] repository of the entire example.
+
+Official [API documentation][1] can be found on [LightningChart][2] website.
+
+If the docs and other materials do not solve your problem as well as implementation help is needed, ask on [StackOverflow][3] (tagged lightningchart).
+
+If you think you found a bug in the LightningChart JavaScript library, please contact sales@lightningchart.com.
+
+Direct developer email support can be purchased through a [Support Plan][4] or by contacting sales@lightningchart.com.
