It is likely that your project already exists at the time of installing the eloquentize package.
It is possible to count data based on "created_at" events retrospectively (for updated_at, it is strongly discouraged because only the last modification will be taken into account, for deleted_at it works, for your custom events you have to determine the relevance).
php artisan eloquentize:models-count-legacy
This command will search for the oldest record among your models and perform the counting day by day from that point on, using the column created_at, so you will be able to generate creation graphs since the launch of your application.
The first argument of the models-count-legacy commands is the day you want to start, if not specified, the command will search for the oldest created model of your database and start from this day.
