Pandas API update

[Azaya89]

• update notebook to match current pandas API
• remove test cell from output in user_guide/Viewing

If it doesn't lead to a notebook that is too heavy, we could leverage Panel to display the outputs generated for the same calls (possibly with some slight differences) with hvplot and pandas plotting backends in tabs.

import matplotlib.pyplot as plt
import numpy as np
import pandas as pd
from bokeh.sampledata.penguins import data as df
import hvplot.pandas
import panel as pn

pn.extension()

def compare(pd_hvplot, pd_plot):
    # Pandas .plot
    fig = pd_plot.figure
    pn_mpl = pn.pane.Matplotlib(fig, dpi=80)
    plt.close(fig)

    # Pandas .hvplot
    pn_hv = pn.pane.HoloViews(pd_hvplot)
    return pn.Tabs(
        ('.hvplot()', pn_hv),
        ('pandas .plot()', pn_mpl),
    )

np.random.seed(123456)
ts = pd.Series(np.random.randn(1000), index=pd.date_range("1/1/2000", periods=1000))
ts = ts.cumsum()

compare(
    ts.plot(backend='hvplot'),
    ts.plot(),
)

Thanks. I will test this and see how it goes.

Cool, though let's wait until this is the appropriate time to work on this.
