title: One horizontal colorbar for seaborn heatmaps subplots and Annot Issue with xticklabels
body: <p>I tried to write multiple heatmaps in one figure.
  I wrote the below code and I have two questions.</p>
  
  <p>(1) I want the data value in each cell and I don't need the axis labels for each picture. Therefore, I set xticklabels, yticklables, and annot; but they were not reflected in the figure. How should I do?
  (2) Can I rotate the color bar? I need one horizontal color bar for this fifure.</p>
  
  <p>I use Python 3.5.2 in Ubuntu 14.04.5 LTS.</p>
  
  <pre><code>import matplotlib.pyplot as plt
  import seaborn as sns
  import pandas as pd
  import numpy as np
  
  %matplotlib notebook
  
  flights = sns.load_dataset("flights")
  flights = flights.pivot("month", "year", "passengers")
  fig = plt.figure(figsize=(15, 8))
  # integral
  plt.subplot(1,2,1)
  sns.set(font_scale=0.8)
  plt.title('integral', fontsize = 1)
  plt.subplots_adjust(top=0.90, left = 0.1)
  sns.heatmap(flights, fmt='d', cmap='gist_gray_r', xticklabels = False, yticklabels = False, annot=True)
  
  #float
  plt.subplot(1,2,2)
  sns.set(font_scale=0.8)
  plt.title('float', fontsize = 1)
  plt.subplots_adjust(top=0.90, left = 0.1)
  sns.heatmap(flights, annot=True, fmt='.2f', cmap='gist_gray_r', xticklabels = False, yticklabels = False)
  
  fig.suptitle('Title for figure', fontsize=20)
  plt.subplots_adjust(top=0.9, left=0.06, bottom=0.08) #後ろ2つ追加
  #x label
  fig.text(0.5, 0.02, 'year', ha='center', va='center')
  #y label
  fig.text(0.02, 0.5, 'month', ha='center', va='center', rotation='vertical')
  
  sns.plt.savefig('heatmap.png')
