Switch to the fastest JavaScript charts in the industry.
Our GPU-accelerated charts are ideal for streaming data in real-time. Plus, our Support Team will be there every step of the way.
I have been using LightningChart JS to generate interactive and real-time representation of large and voluminous financial data. The use of the GPU accelerates the rendering of real-time data feeds, enabling me to monitor the market and look for trading signals effectively.
We selected LightningChart JS for the large number of data points we wished to present to our users which LightningChart® JS could do without any problems. LightningChart® JS also maintained this edge during all the additional interactivity tests performed.
The LightningChart JS has been beneficial for my scientific graphs and charts’ applications. Precise and comprehensive charts to express large volumes of data with remarkable rendering capabilities are made possible by the library.
For us, speed is essential, as if it feels slow, the user will simply not want to use the product. Other chart components proved to be far too limited for our needs, which is why we went for LightningChart.
Our main requirement was to integrate a high-performance plotting library into a web browser-based application. The team decided to select LightningChart due to the outstanding plotting performance and easy integrability with our web browser-based tool.
Our team is working on a project that involves handling a substantial amount of data updates. We conducted extensive comparisons among various charting libraries after reviewing their performance. Ultimately, LightningChart JS emerged as the top performer.
We were looking for a charting library that would allow us to display lung function measurement data such as flow and volume in real-time in the browser, and be able to render in headless mode too. We found what we were looking for with LightningChart JS.

Frequently Asked Questions
What is LightningChart JS, and how does it differ from traditional charting libraries?
LightningChart JS is a GPU-accelerated and WebGL-based JavaScript charting library designed for creating high-performance data visualization applications. Unlike traditional js charting libraries, LightningChart leverages the power of the device’s graphics processor, resulting in efficient data loading, high refresh rates, and smooth interactions, making it significantly faster and more capable of handling large datasets.
How does LightningChart JS handle real-time data plotting compared to traditional graph libraries?
LightningChart JS is specifically designed for real-time data plotting, offering high-performance updates and smooth transitions even with constantly changing data streams. Traditional graph libraries may struggle with real-time plotting due to limited performance, whereas LightningChart JS utilizes GPU acceleration and LightningChart’s proprietary, super-efficient rendering techniques, to ensure a seamless real-time plotting experience.
Can LightningChart JS be integrated with different frontend frameworks?
Yes, LightningChart JS provides integration support for various frontend frameworks and technologies such as React, Angular, Vue.js, ASP.NET, Blazor, Xamarin, iOS, Android, and more. This flexibility enables developers to seamlessly embed LightningChart into their preferred development environment.
How can I install and use LightningChart JS with ReactJS?
You can install LightningChart JS in a ReactJS project using npm or yarn. After installation, you can use LightningChart API to create your own LC-based React chart components and start utilizing powerful data visualization features.
Is LightningChart JS suitable for cross-platform development?
Absolutely, LightningChart JS is designed to work seamlessly across web, mobile, and desktop platforms. Its cross-platform compatibility ensures consistent performance and visual appeal across different devices and operating systems. It’s compatible with Windows, MacOS, Linux, Android and iOS.
What are the benefits of using GPU acceleration and WebGL rendering in LightningChart JS?
GPU acceleration and WebGL rendering in LightningChart JS result in efficient data loading, high refresh rates, smooth interactions, and minimal CPU overhead. This technology significantly enhances the performance of data visualization applications, making them faster and more responsive, even with large datasets.
What kind of amounts of data, can I visualize with LightningChart JS?
A: When visualizing a line chart, as a static dataset, the maximum amount of data can be several Billion data points. In real-time charting applications, 400 trends simultaneously with 1000 data points / s, keeping the refresh rate smooth at 60 FPS. The number of line charts visualized in real-time can exceed 4000. In heatmap charts, around 2 Billion data points are within possibilities.
Can I use LightningChart JS in Fintech (finance/banking/trading) applications?
LightningChart® JS is intended for scientific and engineering applications. It lacks some of the features needed in the industry, such as Technical Analysis charts, candlestick charts, and trading bar charts. To develop fintech applications, use LightningChart® JS Trader, which has all the features of LightningChart JS included, and more: Technical Analysis charts are included with 100+ indicators, custom candlestick and trading bars charts can be created, and DataGrid can be utilized to create portfolio views and market watch dashboards.
