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.

* Plot to File - Allows you to specify the
file or directory on the file system where
the plot will be written, rather than being
sent directly to a plotter.  If you specify a
file, each plot will erase the old contents
of the file (if any) and write the plotter
HPGL commands to the file.  If you specify an
existing directory, the first plot made
during any session of HP VEE will generate a
file named "plot1" in that directory.
Additional plots to a directory 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 compatible with either the HP-GL or
the 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.

  * Label Using - This option is only
available when one or more stroke fonts
(e.g., Kanji for Japanese) have been
specified in app-defaults.  Refer to "Using
Two-Byte Character Sets" in appendix A of
Using HP VEE for further information.  When
present, this option gives you two choices:

* Stroke Fonts - With this selection, text
and numeric labels are plotted using the
specified stroke font.  Since most plotters
do not directly support Kanji, use this
option for Kanji support.

* Plotter ROM - With this selection, text and
numeric labels are output as HPGL and are to
be converted to strokes by the plotter.  This
won't work for fonts not directly supported
by the plotter.  However, this option may be
desirable if the HPGL commands are to be used
by another software package.

* 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
within the area defined by P1 and P2.
However, the aspect ratio of the original
display object is maintained, so the plotted
image may fill the defined area in only one
direction.

* 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 the 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 two 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.  If a plot is to be output to a
printer, the Plotter Type must 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.  If the current Plotter
Configuration is in the Plot to File mode,
you may specify the destination file or
directory name as string data on the Plot
control input.  If no control input value is
given, the file or directory name specified
in Plotter Configuration will be used.

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.
