set_blocks_visibility()

Sets visibility for multiple blocks in batch.

Updates the visibility state for multiple blocks at once, then renders the scene. More efficient than calling set_block_visibility() repeatedly. Works in both desktop and notebook modes.

Parameters
  • visibility (dict[str, bool]) — Dictionary mapping block names to visibility states. True to show the block, False to hide it.

Example​

from pyemsi import Plotter, examples

file_path = examples.transient_path()
plt = Plotter(file_path)
plt.set_scalar("B-Mag (T)")
plt.render()

# Hide blocks '3' and '4' from the transient example
plt.set_blocks_visibility({
    "3": False,
    "4": False,
})

# Restore visibility
plt.set_blocks_visibility({
    "3": True,
    "4": True,
})

Notebook Mode​

This method works in notebook mode as well, making it useful for interactive visibility control in Jupyter:

from pyemsi import Plotter, examples

file_path = examples.transient_path()
plt = Plotter(file_path, notebook=True)
plt.set_scalar("B-Mag (T)")
plt.show()

# Toggle visibility in notebook
plt.set_blocks_visibility({"4": False})
