Is there a way to stop the gif after one iteration?

[sara-02]

I want to show a bar plot where bar for the next unit on x-axis appear one after the other and then stop once the last point is reached.
I managed to successfully create my bar plot and save the the gif, however the gif loops which I do not want.
Is there a way to repeat loops?

Hey @sara-02!

You're the second person to ask for this functionality! 🙈 (#3)

If there I get 3 more people asking for it, I'll formalize it into a feature 🤓

For now you can work around with:

import gif
from matplotlib import pyplot as plt

x = list(range(100))
y = [10] * len(x)

@gif.frame
def plot(i):
    plt.plot(x[:i], y[:i])
    plt.xlim([0, max(x)])
    plt.ylim([0, max(y) * 2])
    if x[i] > 50 and x[i] < 70:
        plt.axvspan(50, x[i-1], facecolor="Red", ls="--", lw=2.0, alpha=0.2)
    if x[i] >= 70:
        plt.axvspan(50, 70, facecolor="Red", ls="--", lw=2.0, alpha=0.2)

frames = []
for i in range(len(x)):
    frame = plot(i)
    frames.append(frame)

# IMPORTANT SAVE CODE HERE:
frames[0].save(
    "dont_repeat.gif",
    save_all=True,
    append_images=frames[1:],
    duration=70
)

Which will produce (for some reason macOS Preview doesn't support non-looping gifs? But the web does?):

Hope that helps!

hey @maxhumber I tried a similar approach as you mentioned, still not able to stop the loop :/.
Can I share the gist code with you to have a look at?

[maxhumber]

Sure! I'll take a look :)

humble vote for the feature; noob here thanks for creating this package!
