I have the following code

   '7 yr', '10 yr', '20 yr', '30 yr']
fig = px.line(daily, x='Date', title='XX')

fig.update_layout(title_x=0.5, yaxis=dict(tick0 = 0.2, dtick = 2.5))

with the result enter image description here

Answer 1

I believe you're looking for Plotly's Filled Area Plots. If you scroll down a little, you'll find the sample code for a Basic Overlaid Area Chart:

import plotly.graph_objects as go

fig = go.Figure()
fig.add_trace(go.Scatter(x=[1, 2, 3, 4], y=[0, 2, 3, 5], fill='tozeroy')) # fill down to xaxis

fig.show()

I removed the code for the second trace since it looks like you only want to plot a single line.
