display minute bar

[zha0yangchen]

Enhancement description

Currently, backtesting can only display bars at the hourly level or above. Can it be improved to show minute-level bars? This would facilitate more accurate judgment and review of buy and sell points during backtesting.

backtesting can only display bars at the hourly level or above.

This is assuredly not the case! Backtesting.py is agnostic to what "level" of bars it gets fed, as long as they are OHLC(V) bars.

Can you show an example of data you're having issues with?

If working with lots of bars, you might be bitten by bt.plot(..., resample=True). You can turn that off at your own peril.
