Echo   Graphics Demonstration Program
Echo.
Echo.
Echo   This demonstration will provide an overview of the graphics capabilities
Echo   of the plotting software.

Echo   You must unpack the routines before running this demo.  Read the
Echo   Read.1st file and then run UNPACK.
Echo   Hit any key to see Read.1st; Ctrl-Break to end the demo.

Echo   The most important thing to know is that help files are included, and
Echo   may be viewed with the command PLOTHELP.  The help files will now be
Echo   shown; hit ESC to exit the help files and resume the demo, or enter
Echo   the help topic name for more information on the desired item.  Topics
Echo   OVERVIEW and COMMAND SUMMARY are recommended for beginners.  Note that
Echo   the entire help topic name does not need to be entered; just enough
Echo   to distinguish the desired topic.
Echo.

Cls
Echo   The first demostration will display a simple line plot to the screen.
Echo   The data file format is described in PLOTHELP.  In the simplest case,
Echo   the data file contains the following information:
Echo.
Echo      The number of 'lines' of data in the file
Echo      The number of points in each line
Echo      The data for the first line
Echo      The data for the second line
Echo      ... the data for the last line
Echo.
Echo   For example, the plot about to be generated uses the data file TEST.DAT.
Echo   This file contains the following data:
Echo.
Pause
Cls
Type Test.dat
Echo.
Pause
Cls
Echo   Two commands will be used to generate the plot.  The first is TWO_D.
Echo   This command will set up the plot program to generate a two-dimensional
Echo   plot.  The second command is PLOT TEST, which will plot the data file
Echo   TEST.DAT.
Echo.
Echo   When the plot is displayed on the screen, hit any key to get a menu
Echo   of options.  Hit S to save the plot to a disk file, then Q to quit
Echo   the plot program.  Before quitting, you may try hitting L to produce
Echo   a low-resolution plot, or H to produce a high-resolution plot.
Echo.
Pause
command /c two_d
command /c plot test
Cls
Echo   The next example illustrates the use of a three-dimensional surface
Echo   plot.  This example may take several minutes depending on the speed
Echo   of your computer.  For this plot, a header file is used to specify
Echo   various plot parameters.  The HEADER command provides an easy method
Echo   of creating a header file, and HEDIT provides an easy means of editing
Echo   a header file.  The HEDIT program will now be invoked using the
Echo   command HEDIT SINC.HDR.  Use the cursor keys to move through the header
Echo   file; hit function key 2 to see a description of the parameter under
Echo   the cursor, and use Ctrl-Q to exit HEDIT without saving any changes
Echo   you may have made.
Echo.
Pause
Hedit Sinc
Cls
Echo   If the number of parameters is intimidating, bear in mind that default
Echo   values are provided for each parameter so that a full understanding of
Echo   the contents of the header files is not required.
Echo.
Echo   A plot will now be generated using the header file Sinc.hdr and Sinc.dat.
Echo   The command to generate the plot is PLOT /ZI 15 20 1 41 SINC.HDR SINC.DAT.
Echo   Remember to hit S to save the plot to a disk file before hitting Q to return
Echo   to the demo.
Echo.
Echo   This plot may take several minutes to complete.  It will run significantly
Echo   faster on systems using a math coprocessor and running the plot version
Echo   which uses the coprocessor.
Echo.
Pause
If Exist Sinc.dat goto Sinc
Echo   The file Sinc.dat must first be created.  Please be patient; this is
Echo   computationally intesive and may take a while...

Command /c Plot /zi 15 20 1 41 Sinc Sinc
Cls
Echo   The next example illustrates the capability of the program to number
Echo   an axis using a log scale.  The command is:
Echo.
Echo      PLOT /LOGY -5 /ASF LOGXYZ.ASF LOG.HDR LOG.DAT
Echo.
Echo   This may appear cryptic.  The /LOGY -5 specifier instructs the program
Echo   to convert the data in the data file to log values using a minimum value
Echo   of -5 (since the log of zero is negative infinity, a lower limit must
Echo   be specified.) The /ASF LOGXYZ.ASF specifier indicates that the program
Echo   should use the axis specification file LOGXYZ.ASF to define the axis
Echo   scale.  Several example *.ASF files are included on the program disk.
Echo   The LOG.HDR and LOG.DAT specifiers indicate that the file LOG.HDR should
Echo   be used as the header file, and LOG.DAT should be used as the data file.
Echo   (The .DAT and .HDR filename extensions are used by default and may be
Echo   omitted.)  Finally, note that this plot may not look very good on a low
Echo   resolution monitor such as CGA.  The log capability may still by useful
Echo   on CGA systems since a high-resolution plot may be generated independent
Echo   of screen resolution.
Echo.
Echo   (Remember to hit S to save the plot to a disk file before returning to
Echo   the demo.)
Echo.
Pause
Command /c Plot /logy -5 /asf logxyz.asf log log

Echo   All the plots saved to a disk file using this software may be recalled using
Echo   the GALLERY command.
Echo.

Echo   This concludes the demonstration program.  To learn more about using the
Echo   software, read through the help files, and experiment with the examples
Echo   explained therein.
