title: How to annotate 3d plot on Matplotlib?
body: <p>I am trying to annotate a word text on my 3d plot diagram, I know ax.text is able to plot the text on my 3d plot however, the plt.annotate does a better job at that as it arrows the text to the coordinate which is what I need. Is there any way to use plt.annotate to plot on a 3d diagram? I only know that it works on 2d. Do let me know of a solution.</p>
  
  <pre><code>plt.annotate(s='pppppp', xy=(1.5,0), xytext=(1.5,0)) //doesnt work on 3d
  ax.text(1.5,0,0,'pppppp')
  </code></pre>
