Maybe we're talking past each other. The graph we're talking about is a graph of your fuel economy trend. So each point on the graph has an MPG value. Each point on the graph is a point in time, yes, but it's not a timeline with regular intervals. People don't fuel-up at regular intervals, they can skip months at a time and they'd still need to show up on the same graph.
I hear what you're saying—you'd like a way to annotate the graph. So you want to add notes somehow to the existing graph. That's an interesting idea as I mentioned, but it requires completely overhauling the way we do graphs here. We can't simply add the notes as new points on the graph because there's no MPG value. We'll keep it in mind when we look at redesigning our graphs. But it's not possible the way we're doing things now. Sorry about that.
