Customize mplfinance plot python

I trying to change the color of filled shape and add image logo on the top left and price on the right but I don't want price and logo overlapping chart at self, is there is way to move it up?

My code:

 def chartBuilber(self):
    df: DataFrame = pd.DataFrame.from_dict(self.priceHistory()).fillna(method="backfill")
    df.set_index('Date', inplace=True)
    df = df.astype(float)


    market_colors = mpf.make_marketcolors(
        base_mpf_style="yahoo"
    )
    rc = {
        "axes.labelcolor": "none",
        "axes.spines.bottom": True,
        "axes.spines.left": False,
        "axes.spines.right": False,
        "axes.spines.top": False,
        "font.size": 12,
    }

    styles = mpf.make_mpf_style(
        base_mpf_style="nightclouds",
        marketcolors=market_colors,
        gridstyle="",
        rc=rc
    )

    mpf.plot(df, type='line',
             title='Test',
             linecolor='#00ff00',
             style=styles,
             volume=True,
             figsize=(18, 12),
             figscale=0.5,
             fill_between=df['Close'].values,
             tight_layout=True,
             scale_padding={'left': 0.5, 'top': 5, 'right': 0.7, 'bottom': 1})

To change the color of the fill, you can specify fill_between as a dict (instead of list of numbers). In the dict you must specify y1= for the y values (for example, in your case, y1=df['Close'].values). Then add also to the dict facecolor= the color you want for the fill. Thus, something like:

mpf.plot(df,...,fill_between=dict(y1=df['Close'].values`,facecolor='lime'),...)

To get some extra room at the top of the plot, you can use kwarg ylim= specifying a two-element tuple or list (ymin,ymax) where ymax is enough larger than your maximum y-value to give you the amount of space your desire.
