hvPlot.area#

hvPlot.area(x=None, y=None, y2=None, stacked=True, **kwds)[source]#

The area plot can be used to color the area under a line or to color the space between two lines.

Reference: https://hvplot.holoviz.org/ref/api/manual/hvplot.hvPlot.area.html

Plotting options: https://hvplot.holoviz.org/ref/plotting_options/index.html

Parameters:

xstring, optional: Field name(s) to draw x-positions from. If not specified, the index is used. Can refer to continuous and categorical data.
ystring, optional: Field name to draw the first y-position from
y2string, optional: Field name to draw the second y-position from
stackedboolean, optional: Whether to stack multiple areas. Default is True.
**kwdsoptional: Additional keywords arguments are documented in Plotting Options. Run hvplot.help('area') for the full method documentation.

Returns:

holoviews.element.Area / Panel object

You can print the object to study its composition and run:

import holoviews as hv
hv.help(the_holoviews_object)

to learn more about its parameters and options.

Examples#

Simple area plot#

import hvplot.pandas  # noqa
import pandas as pd

df = pd.DataFrame({"x": [0, 1, 2, 3], "y": [0, 1, 4, 9]})

df.hvplot.area(x="x", y="y")

Single area for a timeseries#

This example displays the area under Apple’s stock adjusted closing price over time.

import hvplot.pandas # noqa

df = hvplot.sampledata.apple_stocks("pandas")

df.hvplot.area(x="date", y="adj_close", color="#1e85f7", alpha=0.5, height=300)

Stacked area for multiple series#

This example shows stacked areas for several tech company stock prices. stack is True by default.

import hvplot.pandas # noqa

df = hvplot.sampledata.stocks("pandas")

df.hvplot.area(x="date", y=["Apple", "Amazon", "Netflix"], alpha=0.4, ylim=(1, None))

Non-stacked area for multiple series#

This example shows non-stacked areas for several tech company stock prices, by setting stacked to False. Note that alpha is automatically set to 0.5 in this case.

import hvplot.pandas # noqa

df = hvplot.sampledata.stocks("pandas")

df.hvplot.area(x="date", y=["Apple", "Amazon", "Netflix"], ylim=(1, None), stacked=False)

Area between two lines using y and y2#

This example fills the space between the low and high prices of Apple’s stock, by setting y (low) and y2 (high).

import hvplot.pandas # noqa
import pandas as pd

df = hvplot.sampledata.apple_stocks("pandas")

df.hvplot.area(
    x="date",
    y="low",
    y2="high",
    ylabel="Prices",
    xlim=(pd.Timestamp("2023-03-01"), pd.Timestamp("2023-11-01")),
    ylim=(140, 200),
)
