Salvatoor's Multi-Media Twd Timeline

I made this timeline of events belonging to the comic series, the novles and the Telltale game, which supposedly take place in the same universe. I used Merle Dixon's timeline as a reference for a few of the events, but I modified a couple of the dates based on stuff the comic characters say.
I had previously made a graph that follows the events of every character that joins Rick's group issue to issue. In this case, the events are organized by time, and only 3 of the characters (The most significant one from every type of media) have specific timelines that show the location of that character for reference. Events belonging to the comic are marked in yellow, events belonging to the novels are marked in red and events belonging to the game are marked in green (and they are not explicitly told, because so much stuff happens in them)

WARNING: If you haven't read the novels but want to, this could be a spoiler. If you aren't up to dat with the comics, same thing, If you haven't played the game you can probably read it without anything being spoiled, because the events of the game are not told explicitly.

It's not very attractive visually, because, like the other graph I did, it's made in excel, but if someone can give me some advice on how to improve it, it would be great =)

Also, if you find anything you consider to be wrong, please tell me so I can keep working on it.

And also, most of the events are based on some piece of information, if you want to know what a certain event is based on, ask me and I'll tell you =)

oh, in case it's too confusing, events are put in different levels so that the text could enter, but what matters is the place they are horizontally. The months are divided in early, mid and late.
