Plot#
- property Series.plot: SeriesPlot[source]#
Create a plot namespace.
Warning
This functionality is currently considered unstable. It may be changed at any point without it being considered a breaking change.
Changed in version 1.6.0: In prior versions of Polars, HvPlot was the plotting backend. If you would like to restore the previous plotting functionality, all you need to do is add
import hvplot.polars
at the top of your script and replacedf.plot
withdf.hvplot
.Polars does not implement plotting logic itself, but instead defers to Altair:
s.plot.hist(**kwargs)
is shorthand foralt.Chart(s.to_frame()).mark_bar().encode(x=alt.X(f'{s.name}:Q', bin=True), y='count()', **kwargs).interactive()
s.plot.kde(**kwargs)
is shorthand foralt.Chart(s.to_frame()).transform_density(s.name, as_=[s.name, 'density']).mark_area().encode(x=s.name, y='density:Q', **kwargs).interactive()
for any other attribute
attr
,s.plot.attr(**kwargs)
is shorthand foralt.Chart(s.to_frame().with_row_index()).mark_attr().encode(x='index', y=s.name, **kwargs).interactive()
Examples
Histogram:
>>> s = pl.Series([1, 4, 4, 6, 2, 4, 3, 5, 5, 7, 1]) >>> s.plot.hist()
KDE plot:
>>> s.plot.kde()
Line plot:
>>> s.plot.line()
