[Bug]: AttributeError: 'TimedAnimation' object has no attribute '_framedata' #30831
Description
Bug summary
Hi,
I try to use TimedAnimation class to manage a figure which should plot some sensor data sent in synchronized way, but an AttributeError occurs and I see that in the documentation there is no "_framedata" parameter to set.
Code for reproduction
# The code I try to run is this one
# Matplotlib config
fig, ax = plt.subplots()
ax.grid()
ax.relim() # recompute the ax.dataLim
ax.autoscale_view() # update ax.viewLim using the new dataLim
line, = ax.plot([], [], lw=2)
xdata, ydata = [0], [0]
del xdata[:]
del ydata[:]
line.set_data(xdata, ydata)
t = itertools.count(start=0)
plt.pause(3)
# The errors occurs after in the TimedAnimation
ani_t = animation.TimedAnimation(fig, interval=10, repeat=True, blit=True)
# This line will be not executed
plt.show(block=False)Actual outcome
Traceback (most recent call last):
File "file.py", line 337, in <module>
ani_t = animation.TimedAnimation(fig, interval=10, repeat=True, blit=True)

AttributeError: 'TimedAnimation' object has no attribute '_framedata'
venv/lib/python3.12/site-packages/matplotlib/animation.py:908: UserWarning: Animation was deleted without rendering anything. This is most likely not intended. To prevent deletion, assign the Animation to a variable, e.g. `anim`, that exists until you output the Animation using `plt.show()` or `anim.save()`.
Expected outcome
I expect to plot log data each 10 milliseconds
