JavaScript Surface Partial Invalidation Chart

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.
