How to display node names at all Levels?

[Will Fulton]

Hello, 

I have searched everywhere, but I cannot find a way to create a graph that shows the node name at all levels. I cannot begin to imagine the purpose for creating taxonomy charts that only show the most specific level, and I do not know why it is the default. I tried the show_internal option, and it doesn't work. I know the ETE website has some graphs that show more levels instead of just '1', but I don't see how anywhere. Do you know how to help? Thanks.
