GraphView не рисует

[sergentum]

Привет. Помогите разобраться, пожалуйста, хочу рисовать график с помощью GraphView. График даже строится по тем данным которые добавляются вручную, но те новые, что должны поступать рандомно (а впоследствии с датчиков) не добавлются.
Я думал, может этот участок кода выполняется раз и все, но нет в логах появляется сообщение от строки, которая там рядом.
Пробовал еще выносить ту часть кода где вручную несколько точек задаются, вообще стало null pointer exception.

Что я делаю не так?

GraphView не пользовался, но что-то мне подсказывает, после смены данных в массиве нужно как-то GraphView об этом известить, сам он вряд ли об этом догадается.

вот код который у них на гитхабе лежит, я и не вижу никакой команды типа "отобразить" кроме как хэндлер может что то делает.
у меня код не заработал из-за градлей в которых я не разобрался.
