seaborn.distplot¶

seaborn.distplot(a=None, bins=None, hist=True, kde=True, rug=False, fit=None, hist_kws=None, kde_kws=None, rug_kws=None, fit_kws=None, color=None, vertical=False, norm_hist=False, axlabel=None, label=None, ax=None, x=None)¶

DEPRECATED: Flexibly plot a univariate distribution of observations.

Warning

This function is deprecated and will be removed in a future version. Please adapt your code to use one of two new functions:

displot(), a figure-level function with a similar flexibility over the kind of plot to draw
histplot(), an axes-level function for plotting histograms, including with kernel density smoothing

This function combines the matplotlib hist function (with automatic calculation of a good default bin size) with the seaborn kdeplot() and rugplot() functions. It can also fit scipy.stats distributions and plot the estimated PDF over the data.

Parameters

aSeries, 1d-array, or list.: Observed data. If this is a Series object with a name attribute, the name will be used to label the data axis.
binsargument for matplotlib hist(), or None, optional: Specification of hist bins. If unspecified, as reference rule is used that tries to find a useful default.
histbool, optional: Whether to plot a (normed) histogram.
kdebool, optional: Whether to plot a gaussian kernel density estimate.
rugbool, optional: Whether to draw a rugplot on the support axis.
fitrandom variable object, optional: An object with fit method, returning a tuple that can be passed to a pdf method a positional arguments following a grid of values to evaluate the pdf on.
hist_kwsdict, optional: Keyword arguments for matplotlib.axes.Axes.hist().
kde_kwsdict, optional: Keyword arguments for kdeplot().
rug_kwsdict, optional: Keyword arguments for rugplot().
colormatplotlib color, optional: Color to plot everything but the fitted curve in.
verticalbool, optional: If True, observed values are on y-axis.
norm_histbool, optional: If True, the histogram height shows a density rather than a count. This is implied if a KDE or fitted density is plotted.
axlabelstring, False, or None, optional: Name for the support axis label. If None, will try to get it from a.name if False, do not set a label.
labelstring, optional: Legend label for the relevant component of the plot.
axmatplotlib axis, optional: If provided, plot on this axis.

Returns

axmatplotlib Axes: Returns the Axes object with the plot for further tweaking.

See also

kdeplot: Show a univariate or bivariate distribution with a kernel density estimate.
rugplot: Draw small vertical lines to show each observation in a distribution.

Examples

Show a default plot with a kernel density estimate and histogram with bin size determined automatically with a reference rule:

>>> import seaborn as sns, numpy as np
>>> sns.set_theme(); np.random.seed(0)
>>> x = np.random.randn(100)
>>> ax = sns.distplot(x)

Use Pandas objects to get an informative axis label:

>>> import pandas as pd
>>> x = pd.Series(x, name="x variable")
>>> ax = sns.distplot(x)

Plot the distribution with a kernel density estimate and rug plot:

>>> ax = sns.distplot(x, rug=True, hist=False)

Plot the distribution with a histogram and maximum likelihood gaussian distribution fit:

>>> from scipy.stats import norm
>>> ax = sns.distplot(x, fit=norm, kde=False)

Plot the distribution on the vertical axis:

>>> ax = sns.distplot(x, vertical=True)

Change the color of all the plot elements:

>>> sns.set_color_codes()
>>> ax = sns.distplot(x, color="y")

Pass specific parameters to the underlying plot functions:

>>> ax = sns.distplot(x, rug=True, rug_kws={"color": "g"},
...                   kde_kws={"color": "k", "lw": 3, "label": "KDE"},
...                   hist_kws={"histtype": "step", "linewidth": 3,
...                             "alpha": 1, "color": "g"})
