How to animate a line graph in python where each step of the animation draws an entirely new line based on data in dataframe and export as gif

I would like to animate a line graph in python based on data in my df.

  • For each step in the animation, a line graph would be displayed using one row of the df.
  • A fraction of a second later, a new line graph would be displayed using the next row of data in the df.
  • This process would continue until each row of data had been separately displayed.
  • After this process had been done for all rows, the graph would show the last line of data.
  • I would also have code that converts the animation to a gif and then exports it.

I'm lost as to how to do this and was hoping someone could point me in the right direction.

Here is the code and df I have so far:

# Import dependencies
import pandas as pd
from datetime import datetime

# Create lists to be converted to df
data = [['01/01/2016', 4.17, 4.42, 4.53, 4.71, 4.77, 4.72], 
        ['02/05/2017', 4.59, 4.64, 4.70, 4.74, 4.80, 4.68], 
        ['04/17/2018', 4.67, 4.82, 4.90, 5.02, 5.20, 5.06], 
        ['03/03/2019', 4.70, 4.79, 4.90, 4.80, 4.50, 3.84], 
        ['08/21/2021', 6.02, 5.47, 5.34, 5.55, 5.44, 5.25], 
        ['09/14/2022', 5.18, 5.25, 5.36, 5.37, 5.27, 4.74],
        ['05/05/2023', 5.32, 5.47, 5.46, 5.52, 5.53, 4.64]
       ]

# Create the pandas df
df = pd.DataFrame(data, columns=['date', 'Month 1', 'Month 2', 'Month 3', 
                                 'Month 4', 'Month 5', 'Month 6'])

# Convert 'date' to datetime.
df['date'] = pd.to_datetime(df['date'], format='%m/%d/%Y')

# Display df
display(df)

# Create animated line graph as described in my question

Thanks for any help you can provide.

Confusion between commands.Bot and discord.Client | Which one should I use?

Whenever you look at YouTube tutorials or code from this website there is a real variation. Some developers use client = discord.Client(intents=intents) while the others use bot = commands.Bot(command_prefix="something", intents=intents) . Now I know slightly about the difference but I get errors from different places from my code when I use either of them and its confusing. Especially since there has a few changes over the years in discord.py it is hard to find the real difference. I tried sticking to discord.Client then I found that there are more features in commands.Bot . Then I found errors when using commands.Bot . An example of this is: When I try to use commands.Bot client = commands.Bot(command_prefix=">",intents=intents) async def load(): for filename in os.listdir("./Cogs"): if filename.endswith(".py"): client.load_extension(f"Cogs.{filename[:-3]}") The above doesnt giveany response from my Cogs ...
