TypeError: pivot() takes 1 positional argument but 4 were given in quantstats.reports.html

[Orchid420]

I encountered a TypeError when trying to generate a report using the quantstats.reports.html function. The error message indicates an issue with the pivot method in the quantstats library.

Steps to Reproduce
Set up the environment with the following packages:

Python 3.9.19
pandas 2.2.2
numpy 1.26.4
scipy 1.12.0
matplotlib 3.8.4
seaborn 0.13.2
tabulate 0.9.0
yfinance 0.2.40
plotly 5.20.0
quantstats 0.0.50
Run the following script:

python
Copy code
import pandas as pd
import quantstats as qs
import yfinance as yf

Fetch the daily returns for a stock

stock = qs.utils.download_returns('META')

Ensure datetime index of stock is timezone-naive

stock.index = stock.index.tz_localize(None)

Fetch the benchmark data

benchmark = qs.utils.download_returns('SPY')

Ensure datetime index of benchmark is timezone-naive

benchmark.index = benchmark.index.tz_localize(None)

Ensure the data is aligned by reindexing the benchmark to the stock index

benchmark = benchmark.reindex(stock.index).dropna()

Show sharpe ratio

print(qs.stats.sharpe(stock))

Or using extend_pandas() :)

print(stock.sharpe())

Generate the quantstats report

qs.reports.html(stock, benchmark, output='report.html')
