Displaying price and volume with a plotly chart is bugged in version yfinance==0.2.48

[MaximilianFreitag]

Describe bug

yfinance version ... yfinance==0.2.48
environment google colab

If you want to display the price and volume over time of a certain stock ticker the code does not reproduces the same results as in previous yfinance version. See code example

Simple code that reproduces your problem

#code simply displays the price and volume of Tesla
#after you've run the code restart the kernel and change the yfinance version to !pip install yfinance==0.2.47 to see that #this fixes the problem

!pip install yfinance==0.2.48
import yfinance as yf
import plotly.graph_objects as go
from datetime import datetime, timedelta

start_date = '2023-01-01'
end_date = datetime.now().strftime('%Y-%m-%d')

data = yf.download("TSLA", start=start_date, end=end_date)

fig = go.Figure()
fig.add_trace(go.Scatter(x=data.index, y=data['Close'], name='Price'))
fig.add_trace(go.Bar(x=data.index, y=data['Volume'], name='Volume', yaxis='y2'))

fig.update_layout(
title='TSLA Price and Volume',
yaxis_title='Price',
yaxis2=dict(title='Volume', overlaying='y', side='right'),
