@albertusfreddi
Albertus, Can you please provide the data so that I can reproduce to debug. If you don't already have the data in a csv file, just call df.to_csv('filename.csv') on the dataframe that is giving you the failure.

Thank you. --Daniel

@albertusfreddi ... I am unable unzip the file. When I try "Extract All" on windows, it thinks the zipped folder is empty. And linux unzip, and gunzip both don't like it either.

Hi Albertus,

I was able to plot your data without errors with this code:

import pandas as pd
import mplfinance as mpf

daily = pd.read_csv('debug2.csv',index_col=0,parse_dates=True)
daily.index.name = 'Date'

mpf.plot(daily, type='candle', volume=True, figscale=2.9, style='charles')

This means that the issue is likely with the other arguments you are specifying for the plot() function. I'm not really sure what they are, would you be able to send all the code related to the arguments in your mpf.plot() function call?

You can see the arguments from the traceback in the image provided however the traceback shows the call to mpf.plot() includes an addplot, and the traceback does not show where the data fro the addplot comes from.

@albertusfreddi please include the addplot data, and the code that calls make_addplot(). mplfinance is crashing on a line of code that is attempting to determine the order of magnitude for the addplot data. Certainly, mplfinance should not crash, but in order to put an appropriate check in the code, we will need that data to understand what case we are not handling. Thank you.

No response to previous request for data to reproduce.
