This seems like a simple question, but I can’t find an example. Is it possible to change the opacity of a line plot when using the Plotly backend?
ChatGPT gave me this example, but it doesn’t work.
# Generate time data
time = np.linspace(0, 10, 100)
# Calculate sine wave values
values = np.sin(time)
# Create a DataFrame
df = pd.DataFrame({
'Time': time,
'Sine Wave': values
})
# Define a hook to apply opacity and line width in Plotly
def apply_style(plot, element):
plot.state.traces[0].update(line=dict(width=6, opacity=0.3))
# Create the curve using the hook for styling
sine_wave_plot = hv.Curve(df, 'Time', 'Sine Wave', label='Sine Wave').opts(hooks=[apply_style])
# Create Panel layout
layout = pn.Column("# Sine Wave Visualization", sine_wave_plot)
# Serve the Panel layout
layout.servable(title="Sine Wave Plot")
