I've been following through the simple examples for actions and I'm not sure how to change the setting to get rqt_graph to show nodes a level "deeper".

The action is questions is an exact copy of the ones used in: link

The action node graph they get is: image description

The graph I get instead is: image description

and calling rostopic list -v returns:

morten@mortenThinkPad:~$ rostopic list

/fibonacci/cancel /fibonacci/feedback /fibonacci/goal /fibonacci/result /fibonacci/status /rosout /rosout_agg

I'm relatively new to ROS so I'm not quite sure what other information could be relevant. I'm running ubuntu 16.04LTS with ROS kinetic.

What you are seeing is the ROS nodes. They are shown in bubbles whereas the ROS topics are shown in rectangles. If you want to see both you need to select the drop-down menu from the top-left corner and change it from "Nodes only" to "Nodes/Topics (all)"

After selecting the "nodes/topics (all)" topic the graph doesn't change. Do I need to reload the image.

Possibly yes - click the circular blue arrow in the top-left corner to reload the graph. If that doesn't work, add a screen shot to your question (as gvdhoorn suggested) and add the output of rostopic list.

The formatting got a little weird but I've added the output from rostopic list as well.

@morten_nissov: you have "group namespaces" and "group actions" enabled. That is why your graph looks different from the one shown in the tutorial.

Ah okay, I'll try again without then.

You'll also want to uncheck all the options in the Hide section.
