Multithreading Performance Optimizations
Just when you thought that LightningChart JS could not get any faster, version 8.3 introduces Multi-threading Performance Optimizations as a built-in functionality to make your charts even snappier.
By using multi-threading, we were able to load an absolutely massive data visualization with 40 channels and 10 million data points each in just above 1 second. And you can zoom in/out/reload data without any lag.
