How to get output of pandas .plot(kind=’kde’)?

When I plot density distribution of my pandas Series I use

.plot(kind='kde')

Is it possible to get output values of this plot? If yes how to do this? I need the plotted values.

Answer

There are no output value from .plot(kind='kde'), it returns a axes object.

The raw values can be accessed by _x and _y method of the matplotlib.lines.Line2D object in the plot

In [266]:

ser = pd.Series(np.random.randn(1000))
ax=ser.plot(kind='kde')

In [265]:

ax.get_children() #it is the 3nd object
Out[265]:
[<matplotlib.axis.XAxis at 0x85ea370>,
 <matplotlib.axis.YAxis at 0x8255750>,
 <matplotlib.lines.Line2D at 0x87a5a10>,
 <matplotlib.text.Text at 0x8796f30>,
 <matplotlib.text.Text at 0x87a5850>,

In [264]:
#get the values
ax.get_children()[2]._x
ax.get_children()[2]._y
