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 showcases the partial data update feature of SurfaceGridSeries.
Surface Grid Series allows updating any rectangular sub-section of grid data without affecting any additional data. LightningChart JS has optimized this particular use case really well, whereas most traditional data visualization tools would have to prepare the entire visualization again even if only a small section of data needs to be updated.
In this example, there is a small focus area which is moving periodically along the XZ plane. Every frame, the height data within this focus area is changed.
More commonly, the partial data update feature is used to load large data sets in several smaller "chunks", as showcased in the Chunked Surface Grid Chart Example.
-
Chunked Surface Grid Chart | This example shows how surface grid series can be split into sub sections which are loaded individually for better performance and response time.
-
Intensity Surface Grid Chart | This example showcases how surface grid series can be colored based on a different data set than the height map used in this example.
-
Real-Time Audio Spectrum Surface Chart | This example showcases using real-time data source with surface series.
