Got FutureWarning about _plotting.py

[kaya2k]

Hi, I got hundreds of this same warning using backtest.plot method.

.../venv/lib/python3.8/site-packages/backtesting/_plotting.py:148:
FutureWarning: Passing method to Int64Index.get_loc is deprecated and will raise in a future version. Use index.get_indexer([item], method=...) instead. new_bar_idx = new_index.get_loc(mean_time, method='nearest')

How can I remove this warning? Is there a way to remove it without modifying .../backtesting/_plotting.py file?

I'm currently using Python 3.8.9.

Thanks.

Eventually, we'll have to remove it from the file to avoid using the deprecated code. But you can silence the warning by placing:

import warnings
warnings.simplefilter(action='ignore', category=FutureWarning)

somewhere above your backtest.plot() call, or by setting the environment variable PYTHONWARNINGS:

PYTHONWARNINGS=ignore::FutureWarning

before starting the interpreter.

I was using warnings.simplefilter(action='ignore'), but didn't know that I could give category=FutureWarning option.

Thank you, sir.
