TypeError: distplot() got an unexpected keyword argument 'y'
解决思路
类型错误:distplot()得到了一个意外的关键字参数'y'
解决方法
fg=sns.JointGrid(x=cols[0],y=cols[1],data=data_frame,)
fg.plot_marginals(sns.distplot)distplot()函数中，只接受一个输入数据，即有x，没有y

"""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:
- :func:`displot`, a figure-level function with a similar flexibility
over the kind of plot to draw
- :func:`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 :func:`kdeplot`
and :func:`rugplot` functions. It can also fit ``scipy.stats``
distributions and plot the estimated PDF over the data.
Parameters
----------
a : Series, 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.
bins : argument for matplotlib hist(), or None, optional
Specification of hist bins. If unspecified, as reference rule is used
that tries to find a useful default.
hist : bool, optional
Whether to plot a (normed) histogram.
kde : bool, optional
Whether to plot a gaussian kernel density estimate.
rug : bool, optional
Whether to draw a rugplot on the support axis.
fit : random 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_kws : dict, optional
Keyword arguments for :meth:`matplotlib.axes.Axes.hist`.
kde_kws : dict, optional
Keyword arguments for :func:`kdeplot`.
rug_kws : dict, optional
Keyword arguments for :func:`rugplot`.
color : matplotlib color, optional
Color to plot everything but the fitted curve in.
vertical : bool, optional
If True, observed values are on y-axis.
norm_hist : bool, optional
If True, the histogram height shows a density rather than a count.
This is implied if a KDE or fitted density is plotted.
axlabel : string, 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.
label : string, optional
Legend label for the relevant component of the plot.
ax : matplotlib axis, optional
If provided, plot on this axis.
Returns
-------
ax : matplotlib 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:
.. plot::
:context: close-figs
>>> 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:
.. plot::
:context: close-figs
>>> 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:
.. plot::
:context: close-figs
>>> ax = sns.distplot(x, rug=True, hist=False)
Plot the distribution with a histogram and maximum likelihood gaussian
distribution fit:
.. plot::
:context: close-figs
>>> from scipy.stats import norm
>>> ax = sns.distplot(x, fit=norm, kde=False)
Plot the distribution on the vertical axis:
.. plot::
:context: close-figs
>>> ax = sns.distplot(x, vertical=True)
Change the color of all the plot elements:
.. plot::
:context: close-figs
>>> sns.set_color_codes()
>>> ax = sns.distplot(x, color="y")
Pass specific parameters to the underlying plot functions:
.. plot::
:context: close-figs
>>> 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"})
