Abstract: MULPLT is a multiple file plotting program designed to allow
the easy plotting of scientific data.  It allows for up to 10
data files, scaling and offsetting, linear or log axes, bar
graphs and multiple character fonts derived from the Hershey
characters.  All features of MULPLT may be used
independantly, accessed by the "special features"
options.
 
Current additions to MULPLT include the use of color on those
devices that support it, new command files and overlay
structure supporting a coroutine for VECTOR (so all devices
are built into MULPLT), and several bug fixes.
 
All graphical output of MULPLT is directed through one
subroutine, VECTOR.  VECTOR currently supports the following
devices:
 
. TEKTRONIX 4010 series terminals
. VT100's with : Retrographics, Matrox, Selanar
. Digital Equipment Corporation's GIGI
. HP's 7470 series plotters
. Grinnell systems GMR 37
 
Additions to this list are easy - use one of the existing
subroutines as a template and create your own graphics
driver.
 
MULPLT writes only to vector oriented devices or to a file.
RASTER is able to read these files and is primarily a vector
to raster conversion program, but is also capable of scaling
and offsetting several plots as generated by MULPLT, for
creating banners wider than the line printer or putting
several plots on a single page.  RASTER takes MULPLT vector
files and creates raster images suitable for line printers.
Currently supported raster devices are:
 
. Printronix P300
. Prism printers
. Digital Equipment Corporation's LA50
 
Restrictions: Circular Dimension special feature not working.
