Slider Control v_line

📊 Plotly Python
1

I am trying to make a variant of this example where the slider controls the v_line, but cant get it to work as expected. It returns:

IndexError: list assignment index out of range

This is my code:

import plotly.graph_objects as go
import numpy as np

# Create figure
fig = go.Figure()

# Add hline, one for each slider step
for step in np.arange(0, 5, 0.1):
    fig.add_hline(step, visible=False, 
                  name="𝜈 = " + str(step),
                 )


# Make 10th line visible
fig.layout["shapes"][10].visible = True


# Create and add slider
steps = []
for i in range(len(fig.layout["shapes"])):
    step = dict(
        method="update",
        args=[{"visible": [False] * len(fig.data)},
              {"title": "Slider switched to step: " + str(i)}],  # layout attribute
    )
    step["args"][0]["visible"][i] = True  # Toggle i'th trace to "visible"
    steps.append(step)


sliders = [dict(
    active=10,
    currentvalue={"prefix": "Frequency: "},
    pad={"t": 50},
    steps=steps
)]

fig.update_layout(
    sliders=sliders
)

fig.show()
