Python 如何用 plotly 增加烛台的大小

我一直在编写这段代码来绘制一张烛台图，上面使用了PLATLY的信号和指示器，但由于某些原因，蜡烛太小了.关于如何增加蜡烛的尺寸(不是图表)，有什么帮助吗？

def PLOT_CHART(DF):
fig = make_subplots(rows=2, cols=1, shared_xaxes=True, vertical_spacing=0.03, subplot_titles=('BTCUSDT'), row_heights = [1, 0.3])


fig.add_trace(go.Candlestick(
    x = df.index,
    open = df['Open'],
    high = df['High'],
    low = df['Low'],
    close = df['Close'],
    name = 'BTCUSDT'),
    row = 1, 
    col = 1)

fig.add_trace(go.Scatter(
    x = df.index,
    y = df['vwap'],
    opacity = 0.5,
    line = dict(color='blue'),
    name = 'vwap'),
    row = 1,
    col = 1)

fig.add_trace(go.Scatter(
    x = df.signal_buy.index, 
    y = buy, 
    mode = 'markers', 
    marker_symbol = 'triangle-up', 
    marker_color = 'green', 
    marker_size = 5,
    name = 'Buy signal'), 
    row = 1, 
    col = 1)

fig.add_trace(go.Scatter(
    x = df.signal_sell.index, 
    y = sell, 
    mode = 'markers', 
    marker_symbol = 'triangle-down', 
    marker_color = 'red', 
    marker_size = 5, 
    name = 'Sell signal'), 
    row = 1, 
    col = 1)
    
fig.add_trace(go.Scatter(
    x = df.index,
    y = df['rsi'],
    line = dict(color='white', width=1),
    showlegend = False),
    row = 2,
    col = 1)

fig.update_layout(
    title = 'BTCUSDT',
    yaxis_title = 'Price',
    xaxis_rangeslider_visible = False,
    template = 'plotly_dark',
    showlegend = True,
    #width = 1000,
    height = 800,)

fig.update_yaxes(type = 'log', row = 1, col = 1)
fig.update_yaxes(title_text = 'RSI', row = 2, col = 1)
fig.write_html('BTCUSDT.html', auto_open = True, full_html = True)

fig.show()

PLOT_CHART(DF)

This is the output of the program above个
