Horizontal Bar Chart#

A horizontal bar chart for comparing category values along the y-axis. This example uses the penguins dataset to show average body mass per species.

import hvplot.pandas  # noqa

df = hvplot.sampledata.penguins('pandas')
grouped = df.groupby('species', observed=True)['body_mass_g'].mean()

grouped.hvplot.barh(
    x='species',
    y='body_mass_g',
    title='Horizontal Bar Chart (Bokeh)',
    ylabel='Body Mass (g)',
    xlabel='Species',
)

import hvplot.pandas  # noqa
hvplot.extension('matplotlib')

grouped = df.groupby('species', observed=True)['body_mass_g'].mean()

    x='species',
    y='body_mass_g',
    title='Horizontal Bar Chart (Matplotlib)',
    ylabel='Body Mass (g)',
    xlabel='Species',
