plsdidev

PLSDIDEV(3plplot)						    PLplot API							 PLSDIDEV(3plplot)

NAME

       plsdidev - Set parameters that define current device-space window

SYNOPSIS

       plsdidev(mar, aspect, jx, jy)

DESCRIPTION

       Set  relative  margin width, aspect ratio, and relative justification that define current device-space window.  If you want to just use the
       previous value for any of these, just pass in the magic value PL_NOTSET. It is unlikely that one should ever  need  to  change  the  aspect
       ratio but it's in there for completeness. If plsdidev(3plplot) is not called the default values of mar, jx, and jy are all 0. aspect is set
       to a device-specific value.

       Redacted form: plsdidev(mar, aspect, jx, jy)

       This function is used in example 31.

ARGUMENTS

       mar (PLFLT, input)
	      Relative margin width.

       aspect (PLFLT, input)
	      Aspect ratio.

       jx (PLFLT, input)
	      Relative justification in x. Value must lie in the range -0.5 to 0.5.

       jy (PLFLT, input)
	      Relative justification in y. Value must lie in the range -0.5 to 0.5.
