A question on the computer analysis

Hello,
I have recently played a very interesting game and decided to use the computer analysis. To be quite honest I was a bit confused. It wasn't really clear what the graph had been showing, so I wanted to ask what it actually says.
It also wasn't really clear were the difference between mistake, blunder and inaccuracy was and what defined them. Is it based on official tactics?
Thank you for any answers!

The numbers next to moves or in the graph refer to the evaluation of the position as judged by the computer engine, in "pawns" (just a unit of measurement). Positive + means sente is better, negative - means gote is better. "+2.3" would mean that sente's position overall (material, activity, king safety etc.) is better by 2.3 pawns' worth.

Normal shogi engines measure in terms of centipawns, or 1/100 of a pawn. +1000 (+10.0 in lishogi) is an advantage that professionals would almost always win from, but is still a fight between amateurs. Something like +4000 (+40.0 in lishogi) is a position you really should be winning.

Inaccuracies, mistakes, and blunders are when you make moves that worsen your evaluation by more than a certain amount. Mistakes are more severe than inaccuracies, and blunders are worse than mistakes.
