1. The first frame in a capture does not show in the graph.  It looks like this
also happens for all frames captured within the first 0.001 second.

2. Have a capture with both tcp and udp packages.  Change the "Y Axis Unit" to
"Advanced..." and add a Calc value for "Graph 1", i.e. "udp.length".  Change
the "Y Axis Unit" back to "Packets/Tick" and turn on "Graph 1" and "Graph 2"
without any filters.  The "Graph 1" does only show udp packets while "Graph 2"
shows all packages.  This can lead to wrong graphs without the user knowing
this.

This is observed on OSX, Linux and Windows.
