# ImageWidget supports setting window functions the `time` "t" or `volume` "z" dimension
# These can also be given as kwargs to `ImageWidget` during instantiation
# to set a window function, give a dict in the form of {dim: (func, window_size)}

# change the window size
iw.window_funcs = {"t": (np.mean, 2)}

# change the function

# or reset it

iw.show()
