Pair comparison charts

daspi.plotlib.precast.PairComparisonCharts(source, target, feature, identity, stretch_figsize=False)

Bases: JointChart

Provides a set of charts for visualizing the pairwise comparison of two variables.

PARAMETER	DESCRIPTION
source	The source data. TYPE: DataFrame
target	The target variable(s). TYPE: str or Tuple[str]
feature	The feature variable(s). TYPE: str or Tuple[str]
identity	Column name containing identities of each sample, must occur once for each measurement. TYPE: str
stretch_figsize	If True, the height and width of the figure are stretched based on the number rows and columns in the axes grid. If a float is provided, the figure size is stretched by the given factor. If a tuple of two floats is provided, the figure size is stretched by the given factors for the x and y axis, respectively. by default False. TYPE: bool | float | Tuple[float, float] DEFAULT: False

Examples:

import daspi as dsp

df = dsp.load_dataset('shoe-sole')
chart = dsp.PairComparisonCharts(
        source=df,
        target='wear',
        feature='status',
        identity='tester'
    ).plot(
    ).label(
        info=True
    )

identity = identity instance-attribute

Column name containing identities of each sample.

plot()

Generates a set of two charts for visualizing the difference between each pair. - BlandAltman where the difference is shown on the y-axis - ParallelCoordinate including a MeanTest and QuantileBoxes plot, to reflect the difference within the absolute values.

RETURNS	DESCRIPTION
Self	The PairComparisonCharts instance, for method chaining. TYPE:

label(info=False, **kwds)

Adds titles and labels to the charts generated by the plot() method.

PARAMETER	DESCRIPTION
info	If True, the method will add an informative subtitle to the chart. If a string is provided, it will be used as the subtitle, by default False. TYPE: bool | str DEFAULT: False
**kwds	Additional keyword arguments to be passed to the label() method of the JointChart instance. DEFAULT: {}

RETURNS	DESCRIPTION
Self	The PairComparisonCharts instance, for method chaining.
