Abstract: PLOT-11M is a software package containing a set of
FORTRAN callable graphics subroutines and an XY11
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-11M 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 of up to 200 steps per second.
The subroutine package includes convenient routines for
character or line drawing. As 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 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
