Chart

The chart displays the average ridership for the selected bus routes over time. Users can toggle the y-axis to start at 0.

import plotly.express as px
import plotly.graph_objects as go

fig = plot_ridership_average(rides, 
                             route_numbers=route_numbers, 
                             start_date=datetime(2018, 1, 1), 
                             end_date=datetime(2022, 12, 31), 
                             y_axis_zero = True
                            )

st.plotly_chart(
    fig, 
    use_container_width=True,
    # Increase height of chart
    height=900,
