Abstract: PLOT-11/RSTS for RSTS/E is a software package containing
a set of FORTRAN callable graphics subroutines and an
XY11 or XY311 plotter driver. The subroutine package is
called by a user task. The subroutines operate in
conjunction with the XY11 incremental plotter driver to
provide the user with a versatile plotting capability.
Output can be plotted on-line or spooled to a mass
storage device for later plotting.
 
PLOT-11/RSTS with the XY11 Plotter Control can be interfaced
to a variety of plotters providing the user with drum,
fan-fold, or flat-bed capabilities. Single pen plots of
either .01 inch, .005 inch, or 0.1 millimeter steps can
be generated at speeds up to 200 steps per
second.
 
The subroutine package includes convenient routines for
character or line drawing. As all operations are program
controlled, either axis or both axes can be addressed in
positive or negative incremental steps. The graphics subroutine
library requires 4000 words of memory and consists of the
following:
 
PLOT 		Performs a straight-line move of the pen to a new
		position relative to a reference point. The pen may be either
		plotting or in transition.
WHERE 		Records current pen location and plot-sizing factor.
SYMBOL 		Plots characters of specified height beginning at
		defined X-Y coordinates and at a specified angle with
		respect to the X-axis.
LINE 		Defines the plotting of a graph from an array of points.
AXIS 		Plots the labeled axis from a specific point.
NUMBER  	Plots a floating-point number at a specified height,
		beginning at a defined position and at a specific angle with
		respect to the X-axis. The number of decimal places may
		be specified.
FACTOR 		Enlarges or reduces the size of the plot by a specified
		plot-sizing ratio.
SCALE 		Calculates a scaling factor and a range for an input
		array in conjunction with LINE and AXIS.
NEWDEV 		Provides the ability to change the logical unit number,
		device output, and filename of the output plot file. The output
		device for this feature cannot be an ASCII formatted magnetic
		tape.
