seaborn.relplot¶

seaborn.relplot(x=None, y=None, hue=None, size=None, style=None, data=None, row=None, col=None, col_wrap=None, row_order=None, col_order=None, palette=None, hue_order=None, hue_norm=None, sizes=None, size_order=None, size_norm=None, markers=None, dashes=None, style_order=None, legend='brief', kind='scatter', height=5, aspect=1, facet_kws=None, **kwargs)¶

Figure-level interface for drawing relational plots onto a FacetGrid.

This function provides access to several different axes-level functions that show the relationship between two variables with semantic mappings of subsets. The kind parameter selects the underlying axes-level function to use:

scatterplot() (with kind="scatter"; the default)
lineplot() (with kind="line")

Extra keyword arguments are passed to the underlying function, so you should refer to the documentation for each to see kind-specific options.

The relationship between x and y can be shown for different subsets of the data using the hue, size, and style parameters. These parameters control what visual semantics are used to identify the different subsets. It is possible to show up to three dimensions independently by using all three semantic types, but this style of plot can be hard to interpret and is often ineffective. Using redundant semantics (i.e. both hue and style for the same variable) can be helpful for making graphics more accessible.

See the tutorial for more information.

After plotting, the FacetGrid with the plot is returned and can be used directly to tweak supporting plot details or add other layers.

Note that, unlike when using the underlying plotting functions directly, data must be passed in a long-form DataFrame with variables specified by passing strings to x, y, and other parameters.

Parameters:

Parameters:	x, y : names of variables in `data` Input data variables; must be numeric. hue : name in `data`, optional Grouping variable that will produce elements with different colors. Can be either categorical or numeric, although color mapping will behave differently in latter case. size : name in `data`, optional Grouping variable that will produce elements with different sizes. Can be either categorical or numeric, although size mapping will behave differently in latter case. style : name in `data`, optional Grouping variable that will produce elements with different styles. Can have a numeric dtype but will always be treated as categorical. data : DataFrame Tidy (“long-form”) dataframe where each column is a variable and each row is an observation. row, col : names of variables in `data`, optional Categorical variables that will determine the faceting of the grid. col_wrap : int, optional “Wrap” the column variable at this width, so that the column facets span multiple rows. Incompatible with a `row` facet. row_order, col_order : lists of strings, optional Order to organize the rows and/or columns of the grid in, otherwise the orders are inferred from the data objects. palette : palette name, list, or dict, optional Colors to use for the different levels of the `hue` variable. Should be something that can be interpreted by `color_palette()`, or a dictionary mapping hue levels to matplotlib colors. hue_order : list, optional Specified order for the appearance of the `hue` variable levels, otherwise they are determined from the data. Not relevant when the `hue` variable is numeric. hue_norm : tuple or Normalize object, optional Normalization in data units for colormap applied to the `hue` variable when it is numeric. Not relevant if it is categorical. sizes : list, dict, or tuple, optional An object that determines how sizes are chosen when `size` is used. It can always be a list of size values or a dict mapping levels of the `size` variable to sizes. When `size` is numeric, it can also be a tuple specifying the minimum and maximum size to use such that other values are normalized within this range. size_order : list, optional Specified order for appearance of the `size` variable levels, otherwise they are determined from the data. Not relevant when the `size` variable is numeric. size_norm : tuple or Normalize object, optional Normalization in data units for scaling plot objects when the `size` variable is numeric. legend : “brief”, “full”, or False, optional How to draw the legend. If “brief”, numeric `hue` and `size` variables will be represented with a sample of evenly spaced values. If “full”, every group will get an entry in the legend. If `False`, no legend data is added and no legend is drawn. kind : string, optional Kind of plot to draw, corresponding to a seaborn relational plot. Options are {`scatter` and `line`}. height : scalar, optional Height (in inches) of each facet. See also: `aspect`. aspect : scalar, optional Aspect ratio of each facet, so that `aspect * height` gives the width of each facet in inches. facet_kws : dict, optional Dictionary of other keyword arguments to pass to `FacetGrid`. kwargs : key, value pairings Other keyword arguments are passed through to the underlying plotting function.
Returns:	g : `FacetGrid` Returns the `FacetGrid` object with the plot on it for further tweaking.

x, y : names of variables in data

Input data variables; must be numeric.

hue : name in data, optional

Grouping variable that will produce elements with different colors. Can be either categorical or numeric, although color mapping will behave differently in latter case.

size : name in data, optional

Grouping variable that will produce elements with different sizes. Can be either categorical or numeric, although size mapping will behave differently in latter case.

style : name in data, optional

Grouping variable that will produce elements with different styles. Can have a numeric dtype but will always be treated as categorical.

data : DataFrame

Tidy (“long-form”) dataframe where each column is a variable and each row is an observation.

row, col : names of variables in data, optional

Categorical variables that will determine the faceting of the grid.

col_wrap : int, optional

“Wrap” the column variable at this width, so that the column facets span multiple rows. Incompatible with a row facet.

row_order, col_order : lists of strings, optional

Order to organize the rows and/or columns of the grid in, otherwise the orders are inferred from the data objects.

palette : palette name, list, or dict, optional

Colors to use for the different levels of the hue variable. Should be something that can be interpreted by color_palette(), or a dictionary mapping hue levels to matplotlib colors.

hue_order : list, optional

Specified order for the appearance of the hue variable levels, otherwise they are determined from the data. Not relevant when the hue variable is numeric.

hue_norm : tuple or Normalize object, optional

Normalization in data units for colormap applied to the hue variable when it is numeric. Not relevant if it is categorical.

sizes : list, dict, or tuple, optional

An object that determines how sizes are chosen when size is used. It can always be a list of size values or a dict mapping levels of the size variable to sizes. When size is numeric, it can also be a tuple specifying the minimum and maximum size to use such that other values are normalized within this range.

size_order : list, optional

Specified order for appearance of the size variable levels, otherwise they are determined from the data. Not relevant when the size variable is numeric.

size_norm : tuple or Normalize object, optional

Normalization in data units for scaling plot objects when the size variable is numeric.

legend : “brief”, “full”, or False, optional

How to draw the legend. If “brief”, numeric hue and size variables will be represented with a sample of evenly spaced values. If “full”, every group will get an entry in the legend. If False, no legend data is added and no legend is drawn.

kind : string, optional

Kind of plot to draw, corresponding to a seaborn relational plot. Options are {scatter and line}.

height : scalar, optional

Height (in inches) of each facet. See also: aspect.

aspect : scalar, optional

Aspect ratio of each facet, so that aspect * height gives the width of each facet in inches.

facet_kws : dict, optional

kwargs : key, value pairings

Other keyword arguments are passed through to the underlying plotting function.

Returns:

g : FacetGrid

Returns the FacetGrid object with the plot on it for further tweaking.

Examples

Draw a single facet to use the FacetGrid legend placement:

>>> import seaborn as sns
>>> sns.set(style="ticks")
>>> tips = sns.load_dataset("tips")
>>> g = sns.relplot(x="total_bill", y="tip", hue="day", data=tips)

Facet on the columns with another variable:

>>> g = sns.relplot(x="total_bill", y="tip",
...                 hue="day", col="time", data=tips)

Facet on the columns and rows:

>>> g = sns.relplot(x="total_bill", y="tip", hue="day",
...                 col="time", row="sex", data=tips)

“Wrap” many column facets into multiple rows:

>>> g = sns.relplot(x="total_bill", y="tip", hue="time",
...                 col="day", col_wrap=2, data=tips)

Use multiple semantic variables on each facet with specified attributes:

>>> g = sns.relplot(x="total_bill", y="tip", hue="time", size="size",
...                 palette=["b", "r"], sizes=(10, 100),
...                 col="time", data=tips)

Use a different kind of plot:

>>> fmri = sns.load_dataset("fmri")
>>> g = sns.relplot(x="timepoint", y="signal",
...                 hue="event", style="event", col="region",
...                 kind="line", data=fmri)

Change the size of each facet:

>>> g = sns.relplot(x="timepoint", y="signal",
...                 hue="event", style="event", col="region",
...                 height=5, aspect=.7, kind="line", data=fmri)
