handle графика и появляется возможность посылать GNUPLOT команды для отображения

графиков.

Размер массива `argc` строк. \n

`argv[0]` хранит имя исполняемого файла программы. \n
|

`--plotwin` отображать график в отдельном окне
|

(данный параметр используется по умолчанию);\n

`--plotpng` сохранить график в png-файл, заданный именем

Путь сохранения графика совпадает с путем исполняемого файла
|

программы. \n
|
||||
|

\param[in, out] hplot Указатель на адрес хэндла пакета GNUPLOT. \n

|

но по адресу `hplot` также будет записан `NULL`.

\n
|

После построения графиков необходимо закрыть хэндл GNUPLOT функцией

Пример построения графиков синуса и косинуса привден в следующем листинге:

|

\include gnuplot_script_test.c
|
||||
|
||||
Данная программа рассчитвает значения функций синуса и косинуса,
|

а также сохрянет текстовые файлы `dat/cosine.txt` и `dat/sine.txt`.\n
