Mplfinance: Adjust the candle width

[schorschie]

Hello,

is there a possibility to adjust the candle width (1, 2, 4 hours etc.)?

regards

You should be able to do this using pandas.DataFrame.resample() before passing the data into mpf.plot(). Let me know if you need more detail.

Hello Daniel,
tank you, DataFrame.resample() works great! I already coded a loop, but your way is better:

def adjust_candle_width(ticker_frame, sample_time='1D'):
    adj_ticker_frame = ticker_frame.resample(sample_time).agg({
        'Open': 'first',
        'High': 'max',
        'Low': 'min',
        'Close': 'last',
        'Volume': 'sum'
    })
    return adj_ticker_frame
