seaborn.jointplot(x, y, data=None, kind='scatter', stat_func=None, color=None, height=6, ratio=5, space=0.2, dropna=True, xlim=None, ylim=None, joint_kws=None, marginal_kws=None, annot_kws=None, **kwargs)

Draw a plot of two variables with bivariate and univariate graphs.

This function provides a convenient interface to the JointGrid class, with several canned plot kinds. This is intended to be a fairly lightweight wrapper; if you need more flexibility, you should use JointGrid directly.

参数:x, y:strings or vectors

Data or names of variables in data.

data:DataFrame, optional

DataFrame when x and y are variable names.

kind:{ “scatter” | “reg” | “resid” | “kde” | “hex” }, optional

Kind of plot to draw.

stat_func:callable or None, optional

Deprecated

color:matplotlib color, optional

Color used for the plot elements.

height:numeric, optional

Size of the figure (it will be square).

ratio:numeric, optional

Ratio of joint axes height to marginal axes height.

space:numeric, optional

Space between the joint and marginal axes

dropna:bool, optional

If True, remove observations that are missing from x and y.

{x, y}lim:two-tuples, optional

Axis limits to set before plotting.

{joint, marginal, annot}_kws:dicts, optional

Additional keyword arguments for the plot components.

kwargs:key, value pairings

Additional keyword arguments are passed to the function used to draw the plot on the joint Axes, superseding items in the joint_kws dictionary.

返回值:gridJointGrid

JointGrid object with the plot on it.

Examples

Draw a scatterplot with marginal histograms:

>>> import numpy as np, pandas as pd; np.random.seed(0)
>>> import seaborn as sns; sns.set(style="white", color_codes=True)
>>> tips = sns.load_dataset("tips")
>>> g = sns.jointplot(x="total_bill", y="tip", data=tips)

Add regression and kernel density fits:

>>> g = sns.jointplot("total_bill", "tip", data=tips, kind="reg")

http://seaborn.pydata.org/_images/seaborn-jointplot-2.png

Replace the scatterplot with a joint histogram using hexagonal bins:

>>> g = sns.jointplot("total_bill", "tip", data=tips, kind="hex")

http://seaborn.pydata.org/_images/seaborn-jointplot-3.png

Replace the scatterplots and histograms with density estimates and align the marginal Axes tightly with the joint Axes:

>>> iris = sns.load_dataset("iris")
>>> g = sns.jointplot("sepal_width", "petal_length", data=iris,
...                   kind="kde", space=0, color="g")

http://seaborn.pydata.org/_images/seaborn-jointplot-4.png

Draw a scatterplot, then add a joint density estimate:

>>> g = (sns.jointplot("sepal_length", "sepal_width",
...                    data=iris, color="k")
...         .plot_joint(sns.kdeplot, zorder=0, n_levels=6))

Pass vectors in directly without using Pandas, then name the axes:

>>> x, y = np.random.randn(2, 300)
>>> g = (sns.jointplot(x, y, kind="hex")
...         .set_axis_labels("x", "y"))

http://seaborn.pydata.org/_images/seaborn-jointplot-6.png

Draw a smaller figure with more space devoted to the marginal plots:

>>> g = sns.jointplot("total_bill", "tip", data=tips,
...                   height=5, ratio=3, color="g")

http://seaborn.pydata.org/_images/seaborn-jointplot-7.png

Pass keyword arguments down to the underlying plots:

>>> g = sns.jointplot("petal_length", "sepal_length", data=iris,
...                   marginal_kws=dict(bins=15, rug=True),
...                   annot_kws=dict(stat="r"),
...                   s=40, edgecolor="w", linewidth=1)
