how to add button like this below to toggle data from all traces on the scatter?

Thanks, Paulina
The hover text data comparison button on the menu bar does not appear to be visible at all times. I do not know why. Adding the following code will make it appear. This tips was confirmed from here.
import plotly.graph_objects as go
# Create random data with numpy
import numpy as np
np.random.seed(1)
N = 100
random_x = np.linspace(0, 1, N)
random_y0 = np.random.randn(N) + 5
random_y1 = np.random.randn(N)
random_y2 = np.random.randn(N) - 5
fig = go.Figure()
# Add traces
fig.add_trace(go.Scatter(x=random_x, y=random_y0,
mode='markers',
name='markers'))
fig.add_trace(go.Scatter(x=random_x, y=random_y1,
mode='lines+markers',
name='lines+markers'))
fig.add_trace(go.Scatter(x=random_x, y=random_y2,
mode='lines',
name='lines'))
fig.update_layout(modebar_add=[
"v1hovermode",
"toggleSpikelines",
])
fig
