Then the graph is confusing because the labelled arnt the same with no markers to distinguish differences.

You put in movies which makes the graph appear to be a chronology based on movies and tv shows. You then randomly add in Han Solo only, also using just Solo which there is a movie which gives the reader the assumption that you are tracking where the movie falls in the chronology rather than the character. Its not internally consistent.

Better to keep them separate graphs or at least have distinct markings to differentiate between characters and movies/shows and also include other characters. We know Luke and Leia were born at the end of episode 3 and both live to the end of episode 8 for example. Vader and Obi Wan are born some time before episode 1 and Obi Wan lives until one third of episode 4 and Vader until end of episode 6. Palps is pre-episode 1 to episode 6 with his clone then born and then dies at the end of episode 9.
