title: How can I customize mplfinance.plot?
body: <p>I've made a python script to convert a csv file in a candlestick like this using mpl_finance, this is the script:</p>
  <pre><code>import matplotlib.pyplot as plt
  from mpl_finance import candlestick_ohlc
  import pandas as pd
  import matplotlib.dates as mpl_dates
  
  plt.style.use('ggplot')
  
  # Extracting Data for plotting
  data = pd.read_csv('CSV.csv')
  ohlc = data.loc[:, ['Date', 'Open', 'High', 'Low', 'Close']]
  ohlc['Date'] = pd.to_datetime(ohlc['Date'])
  ohlc['Date'] = ohlc['Date'].apply(mpl_dates.date2num)
  ohlc = ohlc.astype(float)
  
  # Creating Subplots
  fig, ax = plt.subplots()
  plt.axis('off')
  fig.patch.set_facecolor('black')
  
  candlestick_ohlc(ax, ohlc.values, width=0.6, colorup='green', colordown='red', alpha=0.8)
  
  plt.show()
  </code></pre>

  <br /></p>
  <p>Now I need to do the same thing but using mplfinance instead of mpl_finance and I've tried like this:</p>
  <pre><code>import mplfinance as mpf
  # Load data file.
  df = pd.read_csv('CSV.csv', index_col=0, parse_dates=True)
  
  # Plot candlestick.
  # Add volume.
  # Add moving averages: 3,6,9.
  # Save graph to *.png.
  mpf.plot(df, type='candle', style='charles',
          title='',
          ylabel='',
          ylabel_lower='',
          volume=True, 
          mav=(3,6,9), 
          savefig='test-mplfiance.png')
  </code></pre>
  <p>And I have this result:
  <a href="https://i.stack.imgur.com/WCnyA.png" rel="noreferrer"><img src="https://i.stack.imgur.com/WCnyA.png" alt="enter image description here" /></a>
  <br />
  So, now I need to change background color from white to black, remove grid and remove axes but I have no idea how to do it.
  Thanks to all will spend time for reply me.</p>
  <p>[EDIT]: this is an old question I've ade when mpl_finance was at It's first stage, now a lot of things are changed and this question is obsolete.</p>
