Qwt + axisscale Time xBottom

[Mistressgirl]

Здравствуйте. Разбираясь в Qwt и построении графиков в нем соответственно возник вопрос по реализации на оси Х шкалы реального времени. Много статей просмотрел про метод QwtScaleDraw, но так и не смог реализовать в своем коде. У кого найдется минутка прошу подсказать. Спасибо за внимание.
