Simple example of pn.pane.Matplotlib with pn.depends

I started writing a question but I ended up solving my issue. Leaving here for others.

Solution: I didn’t need to call pn.pane.Matplotlib but could simply pass the function to pn.panel

import matplotlib.pyplot as plt
import pandas as pd
import panel as pn

df = pd.DataFrame({"a": [0, 0, 1, 1], "b": [0, 1, 3, 2]})

a = pn.widgets.Select(name="a:", options=[0, 1]).servable()

def plot(a):
    s = df[df["a"] == a]["b"]
    fig, ax = plt.subplots()
    return fig
