About LightningChart JS

LightningChart® is a registered trademark by LightningChart Ltd, a pioneer in high-performance charting. Ever since 2009, the LightningChart team has studied different technologies. Prototyped, researched, and innovated new algorithms, which are now part of LightningChart product lines, to produce the absolute best performance for those advanced applications that need it. LightningChart JS product line was first released in 2019. It is a WebGL-based, cross-platform charting library developed for delivering an exceptional chart performance.

Performance in JavaScript Charts

While almost all charts can provide sufficient performance with 1000 data points, the differences start to show when the data rates and series counts go up. All charts are just not designed for high data rates, and their Canvas/HTML5-based rendering is magnitudes slower than WebGL rendering used in LightningChart JS. So many chart library providers claim to have “extreme performance”, “high-performance charts”, or something even more outrageous and with absolutely no figures to back those statements.

LightningChart JS World’s Fastest JS Library

LightningChart initiated the fact-based performance comparisons of web charts already back in 2021. Since the beginning, LightningChart JS has easily topped the results, and over the years, the testing process has evolved to be more transparent, reproducible, and comprehensive. Previous versions of these Performance Comparisons can be found on GitHub.
