but i keep seeing this message (ā€˜FuncAnimationā€™ object has no attribute ā€˜savefigā€™)whenever i rerun the app. Any idea how can i fix it?

Hey @oumaima,

I suppose you are trying to save a Matplotlib figure on disk, but what you actually build is a Matplotlib animation so it canā€™t be saved using the savefig method.

To save a Matplotlib animation, youā€™ll need to use a more specific writer to convert to a movie file or HTML file. Youā€™ll find details on this page.

Could you share the bit of code that builds the Matplotlib animation and saves it on disk? If youā€™re able to make a small reproducible snippet, this would be really helpful to debug further!

Have a nice day,
Fanilo

well my main concern is to show it on the site.here is my code:

from itertools import count
import pandas as pd
import matplotlib
matplotlib.use('agg')
import matplotlib.pyplot as plt
from matplotlib.animation import FuncAnimation

plt.style.use('fivethirtyeight')

x_vals = []
y_vals = []

index = count()


def animate(i):
    data = pd.read_csv('data.csv')
    x = data['date']
    y = data['price']

    plt.cla()

    plt.plot(x[(len(x)-1-365):], y[(len(y)-1-365):], label='Bitcoin Price by $', linewidth=2)

    plt.legend(loc='upper left')
    plt.tight_layout()


ani = FuncAnimation(plt.gcf(), animate, interval=1000)

plt.tight_layout()
plt.savefig('img&&',dpi=100)
plt.show()
