message_ix_models.model.transport.plot.ComparePDTCap0

class message_ix_models.model.transport.plot.ComparePDTCap0

Bases: ComparePDT

Passenger activity per capita.

Identical to ComparePDT, but reads from pdt-cap.csv instead.

__init__()

Methods

__init__()
add_tasks(c, key, *inputs[, strict])	Add tasks to c to generate and save the Plot.
generate(*paths)	Generate and return the plot.
ggtitle([extra])	Return plotnine.ggtitle including the current date & time.

factor	Unit adjustment factor.
inputs	Keys referring to Quantities or other inputs accepted by generate().
measure	Base name for source data files, for instance pdt.csv.
path	Path for file output.
save_args	Keyword arguments for plotnine.ggplot.save.
single	True if the plot is to be used in a Reporter with keys/tasks for reporting a single scenario.
stage	Workflow stage at which the Plot is to be used.
static	list of plotnine objects that are not dynamic.
suffix	File extension; determines file format.
title	Fixed plot title string.
unit	Units of input files

classmethod add_tasks(c: Computer, key: KeyLike, *inputs, strict: bool = False) → KeyLike

Add tasks to c to generate and save the Plot.

Beyond the base class method, this method:

• Constructs an output path from basename, suffix, and the make_output_path() operator. This in turn uses the c.config values “output_dir” (if stage is .STAGE.REPORT) or “build debug dir”.

• If single is False, adds a key “scenario” with a dummy URL that can be used by ggtitle().

• Appends 2 keys for the above to the inputs for use by save().

basename = 'compare-pdt-cap'

File name base for saving the plot.

factor = 1000.0

Unit adjustment factor.

generate(*paths: Path)

Generate and return the plot.

A subclass of Plot must implement this method.

Parameters:

args (Sequence of pandas.DataFrame or other) –

One argument is given corresponding to each of the inputs.

Because plotnine operates on pandas data structures, save() automatically converts any Quantity inputs to pandas.DataFrame before they are passed to generate().

ggtitle(extra: str | None = None) → PlotAddable

Return plotnine.ggtitle including the current date & time.

groupby_plot(data: DataFrame, *args)

Combination of groupby and ggplot().

Groups by args and yields a series of plotnine.ggplot objects, one per group, with static geoms and ggtitle() appended to each.

inputs: Sequence['KeyLike'] = []

Keys referring to Quantities or other inputs accepted by generate().

classmethod make_task(*inputs)

Return a task tuple to add to a Computer.

Deprecated since version 1.18.0: Use add_tasks() instead.

Parameters:

*inputs (.Key or str or hashable, optional) – If provided, overrides the inputs property of the class.

Returns:

• The first, callable element of the task is save().

• The second element is "config", to access the configuration of the Computer.

• The third and following elements are the inputs.

Return type:

tuple

measure = 'pdt-cap'

Base name for source data files, for instance pdt.csv.

path: Path | None = None

Path for file output. If it is not set, save() will populate it with a value constructed from config["output_dir"], basename, and suffix. The implementation of generate() in a Plot sub-class may assign any other value, for instance one constructed at runtime from the inputs.

save(config, *args, **kwargs) → Path | None

Store the last 2 args appended by add_tasks().

save_args: dict[str, Any] = {'verbose': False}

Keyword arguments for plotnine.ggplot.save.

single: bool = False

True if the plot is to be used in a Reporter with keys/tasks for reporting a single scenario. Use False for plots of data from multiple scenarios.

stage: Literal[STAGE.BUILD, STAGE.REPORT] = 1

Workflow stage at which the Plot is to be used.

static: list['PlotAddable'] = [<plotnine.themes.theme.theme object>, {'color': 'scenario', 'x': 'y', 'y': 'value'}, <plotnine.facets.facet_wrap.facet_wrap object>, <plotnine.geoms.geom_line.geom_line object>, <plotnine.geoms.geom_point.geom_point object>, scale_y_log10(name=None, breaks=True, limits=None, labels=True, expand=None, guide=None, na_value=nan, aesthetics=['y', 'ymin', 'ymax', 'yend', 'yintercept', 'ymin_final', 'ymax_final', 'lower', 'middle', 'upper'], rescaler=<function rescale>, oob=<function censor>, minor_breaks=True, trans='log10'), labs(x=None, y='Activity', alpha=None, color=None, colour=None, fill=None, linetype=None, shape=None, size=None, stroke=None, title=None, subtitle=None, caption=None, tag=None)]

list of plotnine objects that are not dynamic.

Type:

‘Static’ geoms

suffix = '.pdf'

File extension; determines file format.

title: str | None = None

Fixed plot title string. If not given, the first line of the class docstring is used.

unit: str | None = 'km/a'

Units of input files
