Interactive Panel App with `rx`#

A dynamic sine curve that updates based on user-controlled amplitude and frequency. This example uses pn.rx() to link Panel widgets with a plotting function.

import numpy as np
import pandas as pd
import hvplot.pandas  # noqa
import panel as pn

x = np.linspace(0, 4 * np.pi, 200)
df = pd.DataFrame({'x': x})

amp_slider = pn.widgets.FloatSlider(
    name='Amplitude', start=-5.0, end=5.0,
    step=0.1, value=1.0, width=200,
)
freq_slider = pn.widgets.FloatSlider(
    name='Frequency', start=0.1, end=5.1,
    step=0.1, value=1.0, width=200,
)

def sine_plot(amplitude, frequency):
    df['y'] = amplitude * np.sin(frequency * df['x'])
    return df.hvplot.line(
        x='x', y='y', title='Interactive Sine Wave',
        frame_width=400,
    )

pn.rx(sine_plot)(amp_slider, freq_slider)
