title: How to include sample sizes of each node in H2O tree visualization
body: <p>I am working on the visualization of a regression tree using H2O in Python. <a href="https://github.com/h2oai/h2o-tutorials/blob/master/tutorials/display_tree_mojo/DisplayTreeMojoH2O.ipynb" rel="nofollow noreferrer">https://github.com/h2oai/h2o-tutorials/blob/master/tutorials/display_tree_mojo/DisplayTreeMojoH2O.ipynb</a></p>
  
  <p>The example above provides a method of using PrintMOJO. However the output figure does not include the sample size of each node (and the average value of the node). In SKLearn the sample size and average values are included but I don't know how to integrate them in H2O.</p>
  
  <p>This is what I am looking for:

  <p>Any idea?</p>
  
  <p>I looked for a lot of resources but I don't know which option or variable should I play with to make that happen. If I switch to R does that make things easier?</p>
