OK bear in mind that it has been many,many years (maybe 35 ?)since I worked with a scope on ignition systems so my memory can be hazy but if you are talking about the oscillations at the beginning of the voltage /amperage rise and at the zero line after the coil fires I seem to remember oscillations like that being caused by burned points,with the pits and peaks causing varying degrees of resistance which would cause spiking or so called ringing oscillations.
As to finding references to scope patterns on the net,never ran across anything like this..........
Anyone else help ???
