.. _linked_views_example:
Linked Views in Subplots
~~~~~~~~~~~~~~~~~~~~~~~~
This example demonstrates how to create linked views in PyVista subplots
using :func:`~pyvista.Plotter.link_views`, where camera movements
in one view are synchronized with other views. This is particularly useful when comparing
different versions or representations of the same model.
