plotnine.stats.stat_hull

class plotnine.stats.stat_hull(*args, **kwargs)[source]

2 Dimensional Convex Hull

Usage

stat_hull(mapping=None, data=None, geom='path', position='identity',
          na_rm=False, qhull_options=None, **kwargs)

Only the mapping and data can be positional, the rest must be keyword arguments. **kwargs can be aesthetics (or parameters) used by the geom.

Parameters:
mapping : aes, optional

Aesthetic mappings created with aes(). If specified and inherit.aes=True, it is combined with the default mapping for the plot. You must supply mapping if there is no plot mapping.

Aesthetic Default value
x  
y  

The bold aesthetics are required.

Options for computed aesthetics

'area'  # Area of the convex hull
data : dataframe, optional

The data to be displayed in this layer. If None, the data from from the ggplot() call is used. If specified, it overrides the data from the ggplot() call.

geom : str or stat, optional (default: path)

The statistical transformation to use on the data for this layer. If it is a string, it must be the registered and known to Plotnine.

position : str or position, optional (default: identity)

Position adjustment. If it is a string, it must be registered and known to Plotnine.

na_rm : bool, optional (default: False)

If False, removes missing values with a warning. If True silently removes missing values.

qhull_options: str, optional

Additional options to pass to Qhull. See Qhull documentation for details.

Raises:
QhullError

Raised when Qhull encounters an error condition, such as geometrical degeneracy when options to resolve are not enabled.
