How can i have time on my X asis on a real-time chart?

I’m working on the wind-streaming example, i edited so that data is fetched from a MongoDB database instead of SQLite. Now i would like to have time on my X axis instead of a range, so that as soon as it updates, i can see what was the value at X time. Is there a way to accomplish that? I’m assuming i need to use the datetime module but i don’t know how to go forward from here

def gen_wind_speed(interval):
	
	client = MongoClient(port=27017)


	db = client.one

	mycol = client['tst']

	df = pd.DataFrame(list(db.tst.find({})))
	
	

	trace = Scatter(
		y=df['num'],
		line=Line(
			color='#42C4F7'
		),
	)

	layout = Layout(
		height=450,
		xaxis=dict(
			range=[0, 90],
			showgrid=False,
			showline=False,
			zeroline=False,
			fixedrange=True,
			
			title='Time Elapsed (sec)'
		),
		
		margin=Margin(
			t=45,
			l=50,
			r=50
		)
	)

	return Figure(data=[trace], layout=layout)
