Mplfinance: Bug Report: 1 candle would not display correctly.

[toksis]

Describe the bug
I am just posting one candle on a specific time. It will not post correctly.

To Reproduce
Steps to reproduce the behavior:
Just run this code: The csv is on the example folder.
```python

import pandas as pd
import mplfinance as mpf

df = pd.read_csv('data/SPY_20110701_20120630_Bollinger.csv',index_col=0,parse_dates=True)

df = pd.read_csv('SPY_20110701_20120630_Bollinger.csv',index_col=0,parse_dates=True)

x = df.iloc[1:2,:]

mpf.plot(x,type = 'candle')

Expected behavior
It should create a correct candle?

[DanielGoldfarb]

Yes, this looks bad. Will correct it. Thanks for the code to reproduce.

Maybe the issue is that there is no next X (time) variable? so you could not get the width of the body?

[DanielGoldfarb]

Yes, this is a simple thing, and already fixed in my local version. However it was fixed in the context of implementing a new algorithm which nicely adjusts candle widths and volume-bar widths according many aspects of the data ... for example, number data points, frequency of the data (minute-by-minute, hourly, daily, weekly, etc.), whether show_nontrading is True or False: All of these things affect how a particular candle width looks. As you can imagine the algorithm needs to be thoroughly tested for all of these cases (including different styles) before being released. I hope to release it early next week. Thank you for helping. Much appreciated.

Great to see this. I have the same issue. Looking forward to the update. Many thanks DG!

new version 0.12.5 just released to Pypi fixes this.
