'Начало описания
'Данный скрипт рисует графики вероятностных распределений: нормального, биномиального, хи-квадрат;
'Пользователь задаёт число степеней свободы и т.д. Типы графиков и подписи могут
'быть дополнительно настроены из диалогового окна. Скрипт кое-как контролирует вводимые значения
'(знаки и пределы вводимых значений), но пока здесь не реализована проверка против запросов графиков
'с числом категорий, большим, чем SPSS может отобразить: 3000.
