May 10, 2016 · How to pass arguments to animation.FuncAnimation()? I tried, but didn't work. The signature of animation.FuncAnimation() is . class matplotlib.animation.FuncAnimation(fig, func, frames=None, init_func=None, fargs=None, save_count=None, **kwargs) Bases: matplotlib.animation.TimedAnimation. I have pasted my code below.

Aug 27, 2021 · Clearly, I don't understand well enough FuncAnimation. What I want to happen is for the function animate to update the array X , by 'rolling' it one step, as well as doing im.set_array(X) . python

Mar 6, 2017 · Having one FuncAnimation seems to speed things up a lot. It's a noticeable difference after hitting 3 FuncAnimations when the program starts to get a bit choppy. Also, I still need to add potentially another 3 live data charts which is why I need to find a way to optimize it now as I don't think it will go well if I follow the current implentation.

Jun 12, 2023 · For the manual update, I'm accessing anim's generator object that FuncAnimation uses to update the plot. This ensures that when I resume the animation, it starts from the active frame rather than from where it was originally paused.

Sep 19, 2018 · Excellent answer, this has helped a lot. I am still encountering issues trying to get the animation to work at 'real time', however - if I use the linked example and use dt * 1000 (converting to ms, dt = 0.05 so well above the threshold for an interval that is too small) for the interval, the animation works much slower than real time.

Dec 20, 2013 · ani = animation.FuncAnimation(fig, update, frames=data_gen(a), init_func=init, interval=10, blit=True) As a side note, don't use plot as a variable name. A lot of people bulk import pyplot into their name space (such as by ipython --pylab ) which has plot -> matplotlib.pyplot.plot -> plt.gca().plot hence it makes makes it more likely your code ...

Mar 6, 2018 · I am new to python and I'm trying to make an animation and save it into some video format using matplotlibs FuncAnimation. If I run the following code: import numpy as np import matplotlib.animati...
