"""
Colorbars and auto-tiling of overlays in grid mode
==================================================

Demonstrates the colorbar overlay for each layer, as well as the auto-tiling of
overlays. In addition, uses the `gridded` and `position` property of the scale
bar to show that overlays can also be auto-tiled per grid cell. This grid approach
also demonstrates that colorbars are linked to each layer in the grid, and by
toggling the grid mode off, the auto-tiling behavior can be seen.
