Limit number of features in Shapley

Hi,

I'm trying to use the Shapley$new function to get Shapley values for an H2O automl model. I've been able to do that with the existing documentation and outside resources. However, I have a relatively large number of features and the plot is too jumbled to read. I cannot figure out a way to limit the number of features (e.g., top 10 or top 20). Is there a way to do that that I've missed in documentation?

Thank you,
Brian
