Create upper and lower graphs using Plotly

# Data Preparation
x = np.array ([1, 2, 3, 4, 5])
y1 = np.array ([1,3,5,4,2])
y2 = np.array ([2, 4, 3, 1, 5])
y3 = np.array ([6, 4, 2, 5, 3])

# upper graph
config=sp.make_subplots (rows=2, cols=1, shared_xaxes=True, vertical_spacing=0.05)
config.add_trace(go.Scatter(x=x,y=y1,mode='lines+markers',name='y1'),row=1,col=1)
config.update_yaxes(title_text='y1', range=[0,7], row=1, col=1)


# bottom graph
config.add_trace(go.Scatter(x=x,y=y2,mode='lines+markers',name='y2',yaxis="y2"),row=2,col=1)
config.add_trace(go.Bar(x=x,y=y3,name='y3'),row=2,col=1)
config.update_layout(yaxis=dict(title='y2', overlay='y2', side='left', yaxis2=dict(title='y3', side='right')))


# Viewing Graphs
config.update_layout (title='2-stage graph', height=600)
config.show()
