seaborn.jointplot

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

参数：x, y：strings or vectors

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

height：numeric, optional

Size of the figure (it will be square).

ratio：numeric, optional

space：numeric, optional

Space between the joint and marginal axes

：bool, optional

{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：grid：JointGrid

The Grid class used for drawing this plot. Use it directly if you need more flexibility.

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")

Add regression and kernel density fits:

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

Replace the scatterplot with a joint histogram using hexagonal bins:

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

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

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:

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

...                   height=5, ratio=3, color="g")

>>> g = sns.jointplot("petal_length", "sepal_length", data=iris,
...                   marginal_kws=dict(bins=15, rug=True),
...                   annot_kws=dict(stat="r"),
