Feature request: groupby.plot() and groupby.hist() add groupname as figure title

[RolandRitt]

Hello!
I'm plotting histogramms and line plots from a groupby - object. It works fine and for each group a figure is generated. But i think a nice feature would be to automatically add the groupname (label) as figure title to each figure. Below you can see a line and a histplot from one group

My code:

import os
import sys
import datetime
import matplotlib.pyplot as plt
import pandas as pd
import matplotlib.dates as mdates
import numpy as np


%matplotlib notebook


dates = pd.date_range('2013-07-14 11:00:00', '2013-07-16 11:00:00', freq = 's')
cats = np.random.choice(['m', 'f', 'c'], len(dates))
data =np.random.randn(len(dates),1)
data2 =np.random.randn(len(dates),1)

df = pd.DataFrame(data, dates)
df.columns = ['data']
df['cats']= cats
df['data2'] = data2

plt.figure()
ax1 = df.groupby('cats').hist(bins=20, normed=True) #Figure1
#ax1 = df.groupby('cats').plot(subplots=True, layout=(3,1)) #Figure1
plt.figure()
ax1 = df.groupby('cats').plot() #Figure1

Pandas:

pd.__version__
'0.18.0rc1'

I was looking for this functionality and a google search has brought me to an open issue rather than to a solution on stackoverflow :-)
Is there a solution that I'm missing?

I've found a way to add title like this:

my_group = my_data_frame.groupby("name")
my_axes_data_frame = my_group.plot("x", "y")
for index in my_axes_data_frame.index:
    my_axes_data_frame.loc[index].set_title(index)
plt.show()

This works for me with my pandas version 0.23.3.
