Graph Interpretation Graph

Me: So is it a mixture between the tweeter array and the inclined cabinet that minimizes the floor reflections? Is that an over simplification of how you reduce the reflections?

Speaker Guy: That is correct but there's a bit more. Other advantages include lower distortion, wider lateral off axis coverage, and smoother HF response. When listening to loudspeakers the floor reflection is always part of the equation. Our ear-brain mechanism tends to filter this out but not entirely. This is partially why inclined towers have gained favor over the past 30 years

To toss in a couple pennies, AFAIK such a tweeter array isn't the only way to minimize dispersion in the vertical plane; it is one of the reputed advantages of a D'appolito array for example, and I believe ribbons are also effective in controlling/minimizing vertical dispersion as well.

Probably also worth noting that in discussions I've read and taken part in with guys like Granteed and DS-21, dispersion in the vertical plane seems to be almost a non-factor.

Can someone help me interpret these two graphs and what exactly they mean in the area of loudspeaker design. I did some googling, but am still a little confused.

Nothing material or relevant. You can safely ignore them.

I would go so far as to say that using such graphs, along with the meaningless buzzwords in the marketing copy you pasted, is an attempt to pull wool over the eyes of people. And the speaker itself (three tweeter "array," baffle discontinuties) sounds like a train wreck. I'd stay far away.
