[Doc]: Axes limits not updated in animate decay #24296
Description
Documentation Link
Problem
Animate decay claims it shows how to changing axes limits during an animation in the run method
def run(data):
# update the data
t, y = data
xdata.append(t)
ydata.append(y)
xmin, xmax = ax.get_xlim()
if t >= xmax:
ax.set_xlim(xmin, 2*xmax)
ax.figure.canvas.draw()
line.set_data(xdata, ydata)but the limits aren't actually changing:
91679bc3-c559-48dd-8c6e-9f7e9a8157bd.mp4
Suggested improvement
Either option is fine with me:
- fix code so xlims dynamically updated
- remove lim updating code and statement saying this example shows how to update limits

The example works, but that's the default xlim, and it is not running long enough in the docs to show the change. I'm not sure where the cutoff is, as the code itself runs infinitely.

Sphinx gallery is using the default animation save
https://github.com/sphinx-gallery/sphinx-gallery/blob/e2ecb35d9049d0df0a1db4f6d15be817745cd565/sphinx_gallery/scrapers.py#L232
And a really rough experiment indicates that the default save is 100 frames which was apparently deprecated in 2.2, but isn't in the release notes 😕

Slightly related to #24131 (which removes the automatic truncation).
