110502 PLOT-11M Version: V1.2, October 1980 Submitted by: Digital Equipment Corporation Operating System: RSX-11M V3.2 Source Language: FORTRAN IV, FORTRAN IV-PLUS Memory Required: 4KW Hardware Required: XY11 Plotter System Keywords: Plotting 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 tape.
