- (tested on VAXstation 4000-90).
-
- Changes in Version 5.1.0
-
- New Features
-
- 1. A major change in this version allows a program to have more than one
- PGPLOT device open at once. The devices can be of the same type, e.g.,
- two windows on an X-window workstation, or of different types, e.g., a
- Tektronix terminal emulator and a PostScript file. Up to 8 devices may
- be open at once. To support this new feature, four new routines have
- been added: PGOPEN, PGQID, PGSLCT, and PGCLOS, and many routines have
- been modified internally.
-
- At present, support for multiple devices of the same type is not
- complete. Each PGPLOT device driver needs to be modified to support
- multiple devices of the same type (i.e., served by the same driver), or
- to explicitly prohibit opening more than one device. Some of the older
- drivers have not yet been modified, and these drivers may give
- incorrect results if you attempt to use them to open two devices. There
- should never be any problem with unlike devices served by different
- drivers, e.g., /XTERM and /PS.
-
- 2. A new driver (xmdriv) and support routines have been provided by Martin
- Shepherd to facilitate use of PGPLOT in a Motif application. Note that
- this is an experimental driver: feedback would be appreciated.
-
- 3. The C function prototypes (cpgplot.h) and C binding are now compatible
- with C++ as well as C.
-
- Bugs Fixed
-
- A bug has been fixed in GRPOCL (support routine for PGPOLY). This could
- cause overflow and incorrect plots if the world-coordinate values were
- greater than about 1E18 (on most machines). A rounding-error has been fixed
- in GRFA (support routine for PGPOLY); this could cause gaps between polygons
- that should abut.
-
- A bug has been fixed in GRPIXL (support routine for PGPIXL); this should
- improve speed.
-
- Two bugs have been fixed in the X-window driver (XWDRIV): it would sometimes
- cause color maps to be set incorrectly; it allowed only 255 colors, not 256.
-
- Drivers Removed
-
- The following device drivers have been moved into directory
- pgplot/drivers/old, and cannot be selected in a normal installation. I
- believe that no-one is still using these drivers: ardriv.f (Args image
- display), grdriv.f (Grinnell image display), ikdriv (Ikon pixel engine),
- lidriv (Liacom display), pkdriv.f and pzdriv.f (Peritek image displays),
- vedriv.f (Versatec V80 printer).

-
- List of Changes
-
- pgplot
- aaaread.me, copyright notice, makedoc, makehtml
- Updated date and version number.
- drivers.list
- Added XMDRIV (Motif driver). Do not select this unless you have
- the necessary Motif support and plan to write Motif applications
- that call PGPLOT. Removed obsolete drivers as noted above.
- makemake
- Added new subroutines. Added targets pgplot.hlp (VMS help file);
- pgplot-routines.tex (LaTeX); pgmdemo (example Motif application).
- Name changes: pgdisp is now pgdispd (directory); pgview is now
- pgview.app (NeXT).
- makehelp
- (New file.) Script to generate VMS help file.
- maketex
- (New file.) Script to generate LaTeX documentation.
- pgdispd
- Changed name of directory from pgdisp to pgdispd to avoid problems
- if you try to compile PGPLOT in the source directory.
- ver510.txt
- (New file.) List of changes since previous version.
- pgplot/cpg
- cpgdemo.c
- Added a third page to exercise more routines.
- cpgplot.h
- Deleted file (note that this file needs to be created as part of
- the installation).
- pgbind.c
- Added C++ wrapper to the generated cpgplot.h file. Added support
- for const qualified declarations in the function prototypes.
- pgplot/drivers
- gidriv.f, ppdriv.f, psdriv.f, ttdriv, wddriv.f, x2driv.c
- Modified to prevent concurrent access.
- gidriv.f, ppdriv.f, psdriv.f, wddriv.f
- On some systems the decoding of environment variables
- PGPLOT_xx_WIDTH, HEIGHT failed owing to a bad Fortran format.
- Rewritten to avoid this problem.
- nudriv.f
- Modified to allow concurrent access (up to 8 devices).
- xmdriv.c, pgxwin.c, pgxwin.h
- New files: PGPLOT driver for Motif applications (from Martin
- Shepherd).
- xwdriv.c
- Fix bug in handling query-color-representation.
- pgxwin_server.c
- Fix bug: 256 colors allowed, not 255.
- pgplot/drivers/old
- New directory: several obsolete drivers (and associated drivers.list)
- have been moved from pgplot/drivers into this directory. These drivers
- should not be used; contact Tim Pearson if you still have a need for
- any of them.
- pgplot/drivers/xmotif
- New directory: support routines and example program for Motif
- applications.
- pgplot/examples
- Some of the example programs have been modified to use PGOPEN/PGCLOS
- instead of PGBEG/PGEND.
- pgdemo1.f
- Changed the pseudo-random number generator to avoid integer
- overflows.
- pgdemo6.f
- `+' key now cycles between cursor modes (rubber-band, cross-hair,
- etc.)
- pgdemo13.f
- (New program) Demonstration of two open devices.
- pgdemo14.f
- (New program) This program demonstrates a method of coding a user
- interface in PGPLOT. It requires the /XSERV device. For a more
- professional approach to graphical user interfaces, consider using
- the PGPLOT Motif driver.
- pgplot/src
- (Many pg routines)
- Changed the C function prototypes to use the const qualifier where
- appropriate. This makes it easier to use the function prototypes
- with C++. Most arguments declared float * or char * are now const
- float * or const char * (except for returned values).
- grpckg1.inc
- Modified to allow up to 8 concurrent devices.
- grfa.f
- Rounding-error fix (thanks to Remko Scharroo; twice).
- grinit.f
- New routine: initializes common block (avoids BLOCK DATA).
- grpixl.f
- Minor bug fix (Remko Scharroo).
- grpocl.f
- Rewrite to avoid potential overflow (thanks to Tomasz Plewa).
- pgplot.inc
- Modified to allow up to 8 concurrent devices; many variables
- changed from scalars to arrays, with new names.
- pgask.f, pgband.f, pgbbuf.f, pgbeg.f, pgbox.f, pgcirc.f, pgebuf.f,
- pgend.f, pgerrb.f, pgerrx.f, pgerry.f, pggray.f, pghi2d.f, pgiden.f,
- pgimag.f, pglen.f, pgmtxt.f, pgncur.f, pgnoto.f, pgpage.f, pgpanl.f,
- pgpap.f, pgpoly.f, pgptxt.f, pgqah.f, pgqch.f, pgqcir.f, pgqcs.f,

- pgshs.f, pgsitf.f, pgstbg.f, pgsubp.f, pgsvp.f, pgswin.f, pgvsiz.f,
- pgvstd.f, pgvw.f, pgwnad.f
- Modified to allow multiple concurrent devices.
- pgclos.f
- (New routine.) Closes the currently selected graphics device.
- pginit.f
- (New internal routine.) Initialize PGPLOT (this is to avoid an
- illegal initialization of data in COMMON).
- pgopen.f
- (New routine.) Open (and select) a graphics device; unlike PGBEG,
- this does not close any previously opened device.
- pgqid.f
- (New routine.) Returns the identifier of the currently selected
- graphics device, for use with PGSLCT.
- pgslct.f
- (New routine.) Selects one of the open devices for graphics
- output.

- pgplot/sys_*
- Changes to configuration files to support compilation of the Motif
- driver and example programs.
- pgplot/sys_arc
- Contents of directory updated for version 5.1.0 by Dave Crennell. See
- file AAAREADME.
- pgplot/sys_linux
- The current version of gcc does not require system-specific variants of
- any files. The variants for f2c have been moved into a subdirectory
- pgplot/sys_linux/f77_src and the configuration files have been modified
- accordingly.
- pgplot/sys_mac
- Contents of directory updated for version 5.0.3 by J. S. Salmento. See
- file aaaread.me.
- pgplot/sys_msdos
- Contents of directory updated for version 5.1.0 by C. T. Dum. See file
- aaaread.me.
- pgplot/sys_next
- Contents of directory updated for version 5.1.0 and NeXtStep 3.0 by
- Allyn Tennant. Configuration file for GNU Fortran (g77) added. See file
- aaaread.me.
- pgplot/sys_sol2
- Added -R options to the ld commands in the configuration files; these
- help the demo programs to find the PGPLOT shared library at run time
- (assuming you haven't moved it after compilation.)
- pgplot/sys_sun4
- Changed version number from 1.7 to 1.8 in all .conf files.
- pgplot/sys_vms
- build.com, compile.com
- Added new routines to shared library transfer vector. Added
- instructions for linking with Motif library when needed.
- grlgtr.f
- This routine formerly converted all PGPLOT device specifications
- to uppercase for VMS. It now preserves case (VMS file and device
- names are not case-sensitive, but some PGPLOT device
- specifications can be).
- install.com
- Added new target (pgmdemo) to compile/install the Motif
- demonstration program.
- make_cpg.com
- Corrected to use the version of cpgplot.h in the current
- directory; set correct protection on generated files.
- make_pgdisp.com
- Changed name of directory from PGDISP to PGDISPD.
- make_pgmdemo.com
- (New file.) Used in compilation of the Motif example program.
- pgplot/sys_win
- New directory: from Phil Seeger. Port of version 5.1.0 to MS
- PowerStation Fortran/Windows95 (or WindowsNT) environment. See file
