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 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.
This example is based on a real life usage scenario of LightningChart JS in the field of Fiber Analysis.
Fiber Analysis refers to the assessment of fiber quality to analyze attenuation and other fiber optic performance metrics during single point of time or across a time period.
This example showcases an example dashboard for analyzing fiber properties over a short time period (~30 seconds).
The metrics are gathered at several locations across the fiber to help spot problem locations (total fibre length is more than 3 kilometers).
The primary metric, intensity, is recorded for each location along fibre (meters) and for various time steps. The intensity value is abstract, meaning that it could reflect many different values for different analysis purposes. A common property in fiber metrics to analyse is Attenuation.
The color of each sample is colored in a heat map grid series based on a color lookup table, which makes identifying hot spots convenient (for example, orange is bad, blue is ok).
The data used in the example is randomly generated each time the example is run.
