title: How to save a nltk FreqDist plot?
body: <p>I've tried different methods to save my plot but every thing I've tried has turned up with a blank image and I'm not currently out of ideas. Any help with other suggestions that could fix this? The code sample is below.</p>
  
  <pre><code>word_frequency = nltk.FreqDist(merged_lemmatizedTokens) #obtains frequency distribution for each token
  print("\nMost frequent top-10 words: ", word_frequency.most_common(10))
  word_frequency.plot(10, title='Top 10 Most Common Words in Corpus')
  plt.savefig('img_top10_common.png')
  </code></pre>
