Xmgr Release v3.01 patchlevel #7

YOU MAY MAKE COPIES OF XMGR FOR YOUR OWN USE, AND MODIFY THOSE COPIES.
YOU MAY NOT DISTRIBUTE ANY MODIFIED SOURCE CODE OR DOCUMENTATION TO USERS 
AT ANY SITES OTHER THAN YOUR OWN.

This is xmgr Release 3.01pl6, a plotting tool for workstations using X/Motif.
Source code is available via anonymous ftp to:

    ftp://ftp.teleport.com/pub/users/pturner/acegr/xmgr-3.01pl6.tar.gz

To build xmgr, cd to xmgr-3.01pl6/src, edit the Makefile and type 'make', 
or use the Imakefile. I don't use imake in the course of development so 
there are most likely problems with the Imakefile.

For a demo, in xmgr-3.01pl6/examples is a script 'dotest' (see the file 
README.ex in the examples subdirectory about the particulars of the 
script), edit 'dotest' to make sure that the variable ACEGR is pointing
to the correct executable. You might let me know about problems you may 
encounter running the demos. Some of the demos are for color systems 
only and will not draw meaningful graphs on mono or grayscale systems.

Xmgr 3.01 has been compiled on SGIs, RS6000s, Decstations, DEC
Alpha, Suns (SunOS 4.1.x and Solaris), HP 7xx, and Linux. I'm very interested 
in compilation on other platforms.

On some systems, the file pars.c will need to be compiled separately. Use the 
'cc' command provided in the Makefile to compile pars.c, then 'make' to 
resume the compilation.

RELEASE NOTES:

This version will not compile on systems using X11R3 with Motif 1.0x.

Documentation is in better shape but a lot of work remains.

Linux is now my primary development system.

There is now a mailing list for users of ACE/gr send mail to:

CHANGES:

-----------------------------------------
From 3.01pl6 to 3.01pl7

* Added support for setting the widths of bar charts

-----------------------------------------
From 3.01pl5 to 3.01pl6

* A bug Graph/Copy that lead to improperly pointing strings used for
  title and subtitles.
* Couldn't change the focus when the graph with the current focus had
  ist axes inverted.

-----------------------------------------
From 3.01pl4 to 3.01pl5

* A bug in the legend drawing routine that caused line styles
  to be drawn incorrectly.

-----------------------------------------
From 3.01pl3 to 3.01pl4

* Method of getting file name from file selection boxes was broken.

* Legends in the UI are supported for MAXPLOT sets only (30).

* If a parameter file is given on the command line, use it as the
  default in the file selection dialog for parameters.
  
-----------------------------------------
From 3.01pl2 to 3.01pl3

* Push n Zoom did not save the tick precision.

* Added ISO Latin encodings by Przemek Klosowski (przemek@rrdbartok.nist.gov).
  You can now display the Angstrom symbol. There is no on screen display of
  the extended characters (something will show, but it won't be right). 3.02
  will use the xvertext routines so that it will be a bit more WYSIWYG.
  Use \c to go into the upper 128 characters and \C to return to normal.
  \cE\C is the Angstrom symbol.

* Numerous functions were declared XtCallbackProc when they should've been
  void.

* Fixed some broken links in the HTML documentation.

-----------------------------------------
From 3.01 to 3.01pl2

PostScript documentation provided by Bob Barta (bob@f2ahp3.jhuapl.edu),
look in the contrib directory xmgr-3.01/contrib/ps.

GR_HELPFILE and GR_HELPVIEWER were incorrectly specified in
the Makefile.

Bugs in a couple of PanelChoice items in the tick popups led to
problems with SGI (and possibly SUN) servers. Thanx to 
Joe English <joe@trystero.art.com> for pointing this out.

Blank lines are now used as set separators. If this behavior
causes problems, look in files.c (search for 'commented') and 
uncomment the specified lines in readxy().

Assumption about the way realloc() works was incorrect - there is no
guarantee the the additional memory is zero'ed - this led to core dumps
on SGIs when using the -maxsets commandline parameter.

getvptr() in pars.yacc returned pointers from sets in the current graph
only.

arrange() used for the -arrange command line option was broken.

-----------------------------------------
From 3.00 to 3.01

The following should be closed for 3.01

In Regions/Extract points, the To set is off by one and set 0 cannot
be used as a destination.

HDF variables with names containing imbedded blanks not read.

Nonlinear curve fitting module broken (this is not a 
supported feature).

DX and DY in the yacc grammar refer to X and Y of the current set.
Formerly, these referred to the span of X and Y wrt to the current 
graph.

Selecting the set and graph in Data/Transformations/Histogram have
no effect. Next available set in the current graph is used for the
result.

XYRT data sets can generate errors in PostScript output.
Could be due to small radii.

Delete points in regions causes core dump.

Interpolation module in Data/Transformations not implemented.
For a later release.

Information about hot links was not saved properly, nor was
the popup updated when hot link info was read in from a file.

-----------------------------------------
Problems and works in progress:

  * Region operations only work on sets of type XY
  * Log plot major tick spacing needs to be in terms of magnitudes.
  * Changing to PostScript fonts has led to problems with the mapping
	of Greek and special characters (Hershey fonts are still used
	for on screen text). I've tried to adhere to the PostScript
	collating sequence for Greek characters - I've not got to the
	special characters yet, so this remains a problem. There is also
	a difference in size between the Hershey and PostScript fonts
	that leads to problems in getting WYSIWYG hardcopy.
  * The fills and patterns drawn on the screen and the .mif output are
	not matched in the PostScript output. I know how to do it,
	but I haven't found the time.
