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
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
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
FACTOR Enlarges or reduces the size of the plot by a specified
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
