Another name for plot in a story could be'storyline'.
Without more information about the 'by another name story', it's almost impossible to give a full account of its plot. But let's assume it's a story about a person who is forced to live 'by another name'. This could be due to political reasons, escaping from a past life filled with danger or shame. The story might then revolve around how this new name affects their relationships, their self - identity, and their journey through life as they try to keep their true identity a secret while still living as this new - named person.
A yarn can also be another name for a story. This term is often used in a more informal or folksy way. People might say 'spin a yarn' which means to tell a story, usually one that is interesting or perhaps a little exaggerated.
A chronicle. A chronicle is more like a record of events in the order in which they occurred. However, it can also be seen as a type of story, especially when it is told in a more engaging and narrative way, like historical chronicles that describe the lives of people and the events of a particular time period.
A short story can also be called a novelette or a short narrative.
