plot_profit

scikitplot.decile.plot_profit(plot_input, *, fixed_costs, currency='€', variable_costs_per_unit, profit_per_unit, highlight_ntile=None, highlight_how='plot_text', line_kws=None, ref_line_kws=None, legend_kws=None, grid_kws=None, axes_kws=None, annotation_kws=None, footer_kws=None, save_fig=True, save_fig_filename='', **kwargs)

Plot profit curve.

Parameters:

plot_inputpandas.DataFrame

Output of ModelPlotPy.plotting_scope.

fixed_costsfloat

Fixed costs independent of selection size.

currencystr

such as the dollar sign ($), euro sign (€), or pound sign (£). These symbols indicate monetary values in financial contexts.

variable_costs_per_unitfloat

Variable cost per selected unit.

profit_per_unitfloat

Revenue per positive unit.

highlight_ntileint or Sequence[int] or None, default=None

Ntile index/indices to highlight (each in 1..ntiles).

highlight_how{‘plot’, ‘text’, ‘plot_text’}, default=’plot_text’

Where to render highlight information.

line_kws, ref_line_kws, legend_kws, grid_kws, axes_kws, annotation_kws, footer_kwsMapping[str, Any] or None

Per-component styling kwargs.

**kwargsAny

Legacy alias for line_kws.

Returns:

matplotlib.axes.Axes

Axes containing the plot.

Other Parameters:

show_figbool, default=True

Show the plot.

Added in version 0.4.0.

save_figbool, default=False

Save the plot. Used by save_plot_decorator.

Added in version 0.4.0.

save_fig_filenamestr, optional, default=’’

Specify the path and filetype to save the plot. If nothing specified, the plot will be saved as png inside result_images under to the current working directory. Defaults to plot image named to used func.__name__. Used by save_plot_decorator.

Added in version 0.4.0.

overwritebool, optional, default=True

If False and a file exists, auto-increments the filename to avoid overwriting.

Added in version 0.4.0.

add_timestampbool, optional, default=False

Whether to append a timestamp to the filename. Default is False.

Added in version 0.4.0.

verbosebool, optional

If True, enables verbose output with informative messages during execution. Useful for debugging or understanding internal operations such as backend selection, font loading, and file saving status. If False, runs silently unless errors occur.

Default is False.

Added in version 0.4.0: The verbose parameter was added to control logging and user feedback verbosity.

Raises:

_PlotInputError

If plot_input lacks required columns.

• plot_input (DataFrame)

• fixed_costs (float)

• currency (str)

• variable_costs_per_unit (float)

• profit_per_unit (float)

• highlight_ntile (int | Sequence[int] | None)

• highlight_how (Literal['plot', 'text', 'plot_text'])

• legend_kws (Mapping[str, Any] | None)

• grid_kws (Mapping[str, Any] | None)

• axes_kws (Mapping[str, Any] | None)

• annotation_kws (Mapping[str, Any] | None)

• footer_kws (Mapping[str, Any] | None)

• save_fig (bool)

• save_fig_filename (str)

• kwargs (Any)

Return type:

Axes

Profit = revenues - investments.

Highlight lines use cumulative 1..N semantics and include cumpos / cumtot.
