Seaborn-PairGrid

seaborn.pairplot

seaborn.pairplot(data, hue=None, hue_order=None, palette=None, vars=None, x_vars=None, y_vars=None, kind=’scatter’, diag_kind=’hist’, markers=None, size=2.5, aspect=1, dropna=True, plot_kws=None, diag_kws=None, grid_kws=None)

Parameters:

data : DataFrame

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

hue : （根据某一类别进行分类，比如code）string (variable name), optional

Variable in data to map plot aspects to different colors.

hue_order : list of strings

Order for the levels of the hue variable in the palette

palette : dict or seaborn color palette

Set of colors for mapping the hue variable. If a dict, keys should be values in the hue variable.

vars : **DataFrame列名称**list of variable names, optional

Variables within data to use, otherwise use every column with a numeric datatype.

{x, y}_vars : lists of variable names, optional

Variables within data to use separately for the rows and columns of the figure; i.e. to make a non-square plot.

-* kind* : {‘scatter’, ‘reg’}, optional

Kind of plot for the non-identity relationships.

diag_kind : （对脚线图形的种类）{‘hist’, ‘kde’}, optional

Kind of plot for the diagonal subplots.

markers : single matplotlib marker code or list, optional

Either the marker to use for all datapoints or a list of markers with a length the same as the number of levels in the hue variable so that differently colored points will also have different scatterplot markers.

size : scalar, optional

Height (in inches) of each facet.

aspect : scalar, optional

Aspect * size gives the width (in inches) of each facet.

dropna : boolean, optional

Drop missing values from the data before plotting.

{plot, diag, grid}_kws : dicts, optional

Dictionaries of keyword arguments.
