HELP
Changes the plotter configuration choices.

USE
Use Plotter Config to change how or where
HP VEE plots two-dimensional graphical 
displays.

LOCATION
File ==> Preferences ==> Plotter Config

DIALOG INFORMATION
* Plotter Device - Allows you to select from
the set of plotters/printers configured on
your system.  You may also use the default
printer.

* Plotter Directory - Allows you to specify
the directory on the file system where plot
files will be written rather than being sent
directly to a plotter.  The first plot made
during any session of HP VEE will generate a
file named "plot1".  Additional plots during
the same HP VEE session will be named
"plot2", "plot3", etc.  Any of the resulting
plot files can be sent to the plotter using a
standard lp command such as:
  lp -d <plotter> /tmp/veeplot/plot3

* Plotter Type - Identifies the plotter to be
used as either an HP-GL or HP-GL/2 command set.
Use HP-GL/2 for plotters that can also be used
as printers, such as the LaserJet III or the
PaintJet XL with the HP-GL/2 Cartridge.

* Number of Pens - Identifies the number
of physical pens in the plotter.  If 6 pens
are specified, such as for an HP 7475 plotter,
and a display trace attempts to use pen 9,
the pen numbers will wrap and pen 3 will be
used.

* Paper Size - Allows you to select the size
of the paper in the plotter.  Choosing the
size "Special" will allow you to edit the P1
and P2 fields to use a non-standard paper
size, or to plot on only a portion of the
page.  The plotted image will always be
scaled to the maximum size that can fit in
the P1/P2 area.  However, the plotted image
may not fill the P1/P2 area in one direction
in order to maintain the aspect ratio of the
original display object.

* P1 (left, bottom) - Specifies the offset
from the left side and bottom of the
plotter's hard clip limits to the bottom left
corner of the plotting area to be used.

* P2 (right, top) - Specifies the offset
from the right side and top of the
plotter's hard clip limits to the top right
corner of the plotting area to be used.

* Size Units - Allows you to select whether
the P1 and P2 units will be displayed and
entered in either Inches or Millimeters.

NOTES 
HP VEE holds only one configuration for
plotting.  It can be set with Plotter Config
menu item or the Plot menu item on a
graphical display object.  Use the 
Preferences ==> Save Preferences menu pick
to save the current plotter configuration.

To send plots to a local or networked
plotter, your system administrator must first
add the plotter as a spooled device on your
system.

In addition to standard HP-GL plotters such
as the HP 7475, the HP ColorPro (HP 7440), or
the HP 7550, some printers can be used as
plotters, such as the PaintJet XL, and the
LaserJet III.  The HP ColorPro plotter
requires the Graphics Enhancement Cartridge
to plot polar or Smith Chart graticules.  The
PaintJet XL requires the HP-GL/2 Cartridge to
make any plots.  In order to make plots on
the LaserJet III, at least 2 megabytes of
optional memory expansion is required, and
the Page Protection configuration option
should be enabled.  Plots of many vectors,
especially with Polar or Smith chart
graticules, may require even more optional
memory in the LaserJet III.  Any Plot
intended for a printer requires the plotter
type to be set to HP-GL/2, which causes the
proper HP-GL/2 setup sequence to be included
with the plot information.

To generate a plot, either interactively
choose the "Plot" menu entry from the
display's object menu, or programmatically
use the optional "Plot" input control pin on
the display.  The entire view of the display
object will be plotted, and scaled to fill
the defined plotting area, while retaining
the aspect ratio of the original display
object.  By re-sizing the display object, you
can control the aspect ratio of the plotted
image.  By making the display object larger,
you can reduce the relative size of the text
and numeric labels around the plot.
