seaborn.JointGrid¶

class seaborn.JointGrid(x, y, data=None, height=6, ratio=5, space=0.2, dropna=True, xlim=None, ylim=None, size=None)¶

Grid for drawing a bivariate plot with marginal univariate plots.

__init__(x, y, data=None, height=6, ratio=5, space=0.2, dropna=True, xlim=None, ylim=None, size=None)¶

Set up the grid of subplots.

Parameters:

x, y : strings or vectors Data or names of variables in data. data : DataFrame, optional DataFrame when x and y are variable names. height : numeric Size of each side of the figure in inches (it will be square). ratio : numeric Ratio of joint axes size 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.

High-level interface for drawing bivariate plots with several different default plot kinds.

Examples

Initialize the figure but don’t draw any plots onto it:

>>> import seaborn as sns; sns.set(style="ticks", color_codes=True)
>>> tips = sns.load_dataset("tips")
>>> g = sns.JointGrid(x="total_bill", y="tip", data=tips)

Add plots using default parameters:

>>> g = sns.JointGrid(x="total_bill", y="tip", data=tips)
>>> g = g.plot(sns.regplot, sns.distplot)

Draw the join and marginal plots separately, which allows finer-level control other parameters:

>>> import matplotlib.pyplot as plt
>>> g = sns.JointGrid(x="total_bill", y="tip", data=tips)
>>> g = g.plot_joint(plt.scatter, color=".5", edgecolor="white")
>>> g = g.plot_marginals(sns.distplot, kde=False, color=".5")

Draw the two marginal plots separately:

>>> import numpy as np
>>> g = sns.JointGrid(x="total_bill", y="tip", data=tips)
>>> g = g.plot_joint(plt.scatter, color="m", edgecolor="white")
>>> _ = g.ax_marg_x.hist(tips["total_bill"], color="b", alpha=.6,
...                      bins=np.arange(0, 60, 5))
>>> _ = g.ax_marg_y.hist(tips["tip"], color="r", alpha=.6,
...                      orientation="horizontal",
...                      bins=np.arange(0, 12, 1))

Add an annotation with a statistic summarizing the bivariate relationship:

>>> from scipy import stats
>>> g = sns.JointGrid(x="total_bill", y="tip", data=tips)
>>> g = g.plot_joint(plt.scatter,
...                  color="g", s=40, edgecolor="white")
>>> g = g.plot_marginals(sns.distplot, kde=False, color="g")
>>> g = g.annotate(stats.pearsonr)

Use a custom function and formatting for the annotation

>>> g = sns.JointGrid(x="total_bill", y="tip", data=tips)
>>> g = g.plot_joint(plt.scatter,
...                  color="g", s=40, edgecolor="white")
>>> g = g.plot_marginals(sns.distplot, kde=False, color="g")
>>> rsquare = lambda a, b: stats.pearsonr(a, b)[0] ** 2
>>> g = g.annotate(rsquare, template="{stat}: {val:.2f}",
...                stat="$R^2$", loc="upper left", fontsize=12)

Remove the space between the joint and marginal axes:

>>> g = sns.JointGrid(x="total_bill", y="tip", data=tips, space=0)
>>> g = g.plot_joint(sns.kdeplot, cmap="Blues_d")
>>> g = g.plot_marginals(sns.kdeplot, shade=True)

Draw a smaller plot with relatively larger marginal axes:

>>> g = sns.JointGrid(x="total_bill", y="tip", data=tips,
...                   height=5, ratio=2)
>>> g = g.plot_joint(sns.kdeplot, cmap="Reds_d")
>>> g = g.plot_marginals(sns.kdeplot, color="r", shade=True)

Set limits on the axes:

>>> g = sns.JointGrid(x="total_bill", y="tip", data=tips,
...                   xlim=(0, 50), ylim=(0, 8))
>>> g = g.plot_joint(sns.kdeplot, cmap="Purples_d")
>>> g = g.plot_marginals(sns.kdeplot, color="m", shade=True)
