How Can I Customize Mplfinance.plot?

I've made a python script to convert a csv file in a candlestick like this using mpl_finance, this is the script: import matplotlib.pyplot as plt from mpl_finance import candlestic

Solution 1:

The best way to do this is to define your own style using mpf.make_mpf_style() rather than using the default mpf styles.

If using external axes method in mplfinance, you can plot multiple charts as below:

# add your own style by passing in kwargs    
s = mpf.make_mpf_style(base_mpf_style='charles', rc={'font.size': 6})
fig = mpf.figure(figsize=(10, 7), style=s) # pass in the self defined style to the whole canvas
ax = fig.add_subplot(2,1,1) # main candle stick chart subplot, you can also pass in the self defined style here only for this subplot
av = fig.add_subplot(2,1,2, sharex=ax)  # volume chart subplot
mpf.plot(price_data, type='candle', ax=ax, volume=av)

The default mpf styles are as below. I believe 'mike' and 'nighclouds' have dark background, not 100% sure about others, you can choose to work on top of these two.

In [5]:
mpf.available_styles()
Out[5]:
['binance',
 'blueskies',
 'brasil',
 'charles',
 'checkers',
 'classic',
 'default',
 'mike',
 'nightclouds',
 'sas',
 'starsandstripes',
 'yahoo']

The arguments that can be passed in mpf.make_mpf_style() are as below, you can use base_mpf_style, facecolor, gridcolor, gridstyle, gridaxis, rc to customise your own style, and give it a name by using style_name. You can play around with these arguments to see how they turn out.

        'gridcolor'     : { 'Default'     : None,
                            'Validator'   : lambda value: isinstance(value,str) },

        'gridstyle'     : { 'Default'     : None,
                            'Validator'   : lambda value: isinstance(value,str) },

        'gridaxis'      : { 'Default'     : None,
                            'Validator'   : lambda value: value in [ 'vertical'[0:len(value)], 'horizontal'[0:len(value)], 'both'[0:len(value)] ] },

        'y_on_right'    : { 'Default'     : None,
                            'Validator'   : lambda value: isinstance(value,bool) },

        'rc'            : { 'Default'     : None,
                            'Validator'   : lambda value: isinstance(value,dict) },

        'style_name'    : { 'Default'     : None,
                            'Validator'   : lambda value: isinstance(value,str) },

    }
    _validate_vkwargs_dict(vkwargs)
    return vkwargs

Solution 2:

To hide axes add this:

axisoff=True

Solution 3:

First you should upgrade your package to the latest version, then in your code, you can write: mpf.plot(......, axisoff= True) in my experience sometimes when using "axisoff= True", it is usefull to use figscale to obtain better results.
