.. _example_poll_file:
Poll file example
--------------------------------------------
A simple script that polls a data file for changes and then updates
the mayavi pipeline automatically.
This script is to be run like so::
$ mayavi2 -x poll_file.py
Or::
$ python poll_file.py
The script currently defaults to using the example data in
examples/data/heart.vtk. You can try editing that data file or change
this script to point to other data which you can edit.
**Python source code:** :download:`poll_file.py`
