How do I erase the double axis in my bokeh plot

Question

my bokeh plot

#output to file
output_file('index.html', title='Sales Volume')

# Create a ColumnDataSource
sales_cds = ColumnDataSource(df_panda)

# Create and configure the figure
fig = figure(x_axis_type='datetime',
             plot_height=300, plot_width=600,
             title='Sales Volume',
             x_axis_label='Date', y_axis_label='Amount',
             toolbar_location=None)

# Render the figure
glyph = VBar(x="Date", top="Earning", bottom=0, width=0.1, fill_color="#b3de69")
fig.add_glyph(sales_cds, glyph)

xaxis = LinearAxis()
fig.add_layout(xaxis, 'below')

yaxis = LinearAxis()
fig.add_layout(yaxis, 'left')

# Move the legend to the upper left corner
fig.legend.location = 'top_left'

# Preview and save 
show(fig)  # See what I made, and save if I like it

How do I erase the double axis on the left side of my plot and below my plot, that you see in the image above?
