plptex:

Synopsis: Place text in the current sub-plot.

Syntax: plptex ( TEXT, X , Y , DX , DY , JUST )

Description:

	Place TEXT in the plot window.

	X: Specify the X coordinate for text placement.
	Y: Specify the Y coordinate for text placement.
	DX (optional): X + DX specifies the X orientation of the text.
	DY (optional): Y + DY specifies the Y orientation of the text.
	JUST (optional): Specifies the position of the string relative
	      to its reference point. If JUST=0, the reference point
	      is at the left and if JUST=1 it is at the right of the
	      string. Other values of JUST give intermediate
	      justifications.

	Since plptex uses the plot-data coordinates for text
	placement, plptex must be called AFTER the plot is created.

	Note: Some plot devices may require the usage of _plflush() to
	      make the test visible (see `help plot').
