Integration of Histo-Plot Widgets
		      ---------------------------------

This directory contains the files required to integrate
the Histo-Plot widget set into WorkShop Visual 6.0.

Files contained in this directory are as follows:

	README          - These notes.

	Makefile        - creates visu binary with
			  Histo-Plot widgets integrated.

	Plot.xdc        - visu_config configuration file
			  for Plot widgets.

	Plot_stubs.c    - additional code for the Histo-Plot
			  widget integration.

	bitmaps/*.bm    - bitmap and pixmap files to represent
			  Histo-Plot widgets on WorkShop Visual
			  widget palette.

	app-defaults/   - Resources for integration.
	visu

Integrating Histo-Plot widgets with visu
-----------------------------------------------

1.  Start visu_config and use the File/Open menu option to load
the Plot.xdc file.  The following family will be listed:

	Plot

2.  Select the 'Config file' option from the Generate menu.  The
Generate dialog contains a toggle button for each family.  Select
one or more of these families depending on the combination of
widgets that are to be integrated into WorkShop Visual.  Click on
OK to generate the Plot_config.c file.  Repeat this procedure for
the 'Code file' menu option to generate Plot_code.c.

3.  Check that the Makefile has appropriate settings and pathnames
for your system.  Build the WorkShop Visual binary using the following
command:

      make

After the build has successfully completed a 'visu.bin'
executable incorporating the Histo-Plot widgets will have been
created in the current directory.

4.  This binary may be invoked by setting the environment variable
USER_WIDGETS to the name of this directory (i.e. USER_WIDGETS=HistoPlot)
and invoking WorkShop Visual as normal.

5. This widget integration can be made the default for your site by
moving or copying this directory to 'local' (including any bitmap and
app-defaults sub-directories).
