Trying to create an animated GIF with static images obtained from the seaborn library. The code is as follows:

import pandas as pd
import matplotlib.pyplot as plt
import seaborn as sns
import os
import imageio.v3 as iio

image = []
folder = 'C:/Users/admin/PycharmProjects/pythonProject2/Project/Seaborn'



if not os.path.exists(folder):
    os.mkdir(folder)

for month in range(1, 4):
    porosity_cutoff = 250
    highlight_colour = 8
    non_highlight_colour = 10

    df = pd.read_csv('../Список.csv')
    df = df.loc[df['Месяц'] == month].sort_values(by='Баллы', ascending=False)

    df['colours'] = df["Баллы"].apply(lambda x: highlight_colour if x >= porosity_cutoff else non_highlight_colour)

    ax = sns.barplot(data=df.loc[df['Месяц'] == month], x="Баллы", y="Участники", palette="Set1", hue=df['colours'],
                     legend=False)

    plt.axvline(x=250, zorder=0, color='grey', ls='--', lw=1.5)

    plt.text(x=283, y=8, s='Порог допустимых баллов', ha='center', fontsize=11, bbox=dict(facecolor='white',
                                                                                          edgecolor="grey", ls='--'))

    ax.set_title(f"Рейтинг за {month} месяц", size=30)
    ax.set_ylabel("Участники", size=20)
    ax.set_xlabel("Баллы", size=20)

    for i in ax.containers:
        ax.bar_label(i, color="white", padding=-30, fontsize=12)

    filename = f'Рейтинг_{month}.png'

    plt.savefig(filename)

    image.append(iio.imread(filename))

    plt.close()

iio.imwrite('barplot.gif', image, duration=20)

In the end I get three images in png format with graphics, all the images are correct, but the giftcard itself is a static first graph. What can be changed or does not work in general?

Guess it’s about the list image and filling it out wrong

• Provide us with "Список.csv" – steve-ed Commented Mar 9 at 5:13
• you could reduce code to list with three filenames and loop with image.append(iio.imread(filename)) and line with iio.imwrite() – furas Commented Mar 9 at 8:05
• did you check if all PNG has different plot? maybe it generate three images with the same plot and this make problem. – furas Commented Mar 9 at 8:08
• how do you display it? Maybe animated gif correct but you use tool which can display only first frame in animated gif. You may put image directly on web browser and it should show it - and all web browsers can display animated gif. – furas Commented Mar 9 at 8:10

I can create animated gif without problem.

Problem can be only duration - it is in milliseconds and 20 ms is very short time and in some image viewers I can't see how fast frames are changed. When I use 500 ms (0.5 second) then I can see animation. BTW: it seems it can eventually get fps (frames per seconds) instead duration

import imageio.v3 as iio

images = []

for filename in ['1.png', '2.png', '3.png']:
    images.append(iio.imread(filename))

iio.imwrite('animated-gif-20ms.gif',  images, duration=20)
iio.imwrite('animated-gif-500ms.gif', images, duration=500)
iio.imwrite('animated-gif-2fps.gif',  images, fps=2)

Other problem can be also where you check this animation. If I put it directly in web browser (Firefox) or test with some image viewers then it displays animation only once and for duration 20ms I can see only last frame.

Documentation for Supported Formats shows that it uses pillow to create gif
and it can get also other options imageio.plugins.pillow_legacy

If I add loop=0 then image loops in Firefox and in image viewers.

iio.imwrite(..., loop=0)
