All story plots are chronological. They begin with Event A, at a particular point in time, and finish one day or one year or one decade later with Event Z.
The decision you face, when plotting a novel, is whether to present the events in chronological order.
One common way in which the natural running order of a plot in a story is altered is to begin it In Media Res (or "in the middle of things).
Logically, novel plots should begin like this:
Beginning story plots "in the middle of things" involves starting with the "something happening" and then backtracking to show the way things were before the action kicked in.
And the purpose of this, of course, is to hook the readers.
This technique, incidentally, can be used at any point in a novel. Anywhere that you have a scene that is taking its time to get going - because you have a lot of "scene setting" to do first - simply:
Why would you want to? Because occasionally a scene will come along which takes its time to get started and therefore threatens to bore the readers. You can solve this easily by beginning the scene in media res.
Here is an outline of a typical scene in the middle of a novel:
Begin this scene in media res and it might look like this:
You probably won't want to begin every scene in your novel in media res.
Sticking to the chronology is, by and large, the best way to tell a story - in terms of not confusing the readers. Though that is a suggestion, not a rule.
There is nothing stopping you, if you believe you could pull it off, from presenting the events of your story in any damn order you choose.
Quentin Tarantino did precisely that in Pulp Fiction - and I believe that film did okay.
"You will probably have worked out your plot in chronological order, beginning at the beginning and going on to the end and then stopping, which is entirely sensible. You may discover, however, that you can make the story more interesting by playing around with the time."
- Michael Legat
When deciding on the "running order" of story plots, you are limited only by your imagination.
Here are just some of the many possibilities...
Beware, though, of doing any of these things just for the sake of doing them.
If you believe you can tell an entire novel in strict chronological order, with nothing out of place, then do so. There is a lot to be said for not confusing the readers.
If you need to make a few small tweaks to the running order, to ensure that the readers are hooked (particularly in the opening pages), fine. Just make it 100% clear when the narrative is moving back in time...and when it rejoins the present.
If you plan to do something more drastic, make sure you are doing so for a good reason - namely, that it enables you to tell a better story.
Never forget that story plots are merely the delivery devices for entertaining fiction. They should never become the entertainment itself.

And that is the end of this entire section on how to plot a novel. The next thing to learn about is how to structure this plot.
Hang on a minute - isn't structure what plotting is all about?
Yes and no. I explain what I mean by that in the section on Structuring Narrative Writing...
