What do you think?
Such graphs could have provided detailed data. I have full confidence in scientific data and statistics. However, I don't fully believe that this data can make sense for users. Because people need more to change their addiction. And a gambling addict can only change his bad situation if he gets professional help. In conclusion, I have a positive attitude towards graphs that provide us with detailed data. But I don't think they are useful for people who are addicted to gambling. Gambling addiction is a subject of psychology. Data is the subject of statistics.
The data may be useful to gamblers who are still aware of their activities, and want to know where his gambling spending at. But for addicts, such info doesn't matter anymore. As they will continue to play despite of what the stats are telling them.
This stats may be helpful to the casino to learn the behaviour of their players and see what games players are devoting their money into. In that case, they can offer more rewards or other promos that will sustain the interest of the players and spend more money into such games.
