plpat — Set area line fill pattern


plpat(nlin, inc, del)


Sets the area line fill pattern to be used, e.g., for calls to plfill(3plplot). The pattern consists of 1 or 2 sets of parallel lines with specified inclinations and spacings.  The arguments to this routine are the number of sets to use (1 or 2) followed by two vectors (with 1 or 2 elements) specifying the inclinations in tenths of a degree and the spacing in micrometers.  (See also plpsty(3plplot))

Redacted form: General: plpat(inc, del) Perl/PDL: plpat(nlin, inc, del)

This function is used in example 15.


nlin (PLINT(3plplot), input)

Number of sets of lines making up the pattern, either 1 or 2.

inc (PLINT_VECTOR(3plplot), input)

A vector containing nlin values of the inclination in tenths of a degree.  (Should be between -900 and 900).

del (PLINT_VECTOR(3plplot), input)

A vector containing nlin values of the spacing in micrometers between the lines making up the pattern.
