• All modules
  1. Corrected/updated the email addresses for the Chart-Graph listserv.
  2. Changed the convention for setting the debug and save temporary files flag to be consistent with CoralReef and other CAIDA applications. Setting: $Chart::Graph::debug = 1 will turn on debugging for any module and $Chart::Graph::save_tmpfiles = 1 will do the same for saving temporary files.
  3. Converted all documentation to Perl POD format.
  4. Expanded the number of test case examples.
  5. Fixed bug in creation of temporary files that prevented more than one graph to be created at time within a given Perl script.
  6. Moved the graphic files produced in the 'make test' phase of the install into the subdirectory 'test_results' so that they won't clutter the installation directory but are available for inspection.
  7. Changed the output of each test file so that when a test is skipped, an explicit message is given reporting that.
• Graph/Gnuplot.pm
  1. Added recognition and creation of png files.
  2. improved timescale resolution.
  3. added a uts_normalize option to work around a gnuplot bug.
  4. Replaced out of date and awkward html documentation with Perl standard POD documentation.
  5. Implemented date/time handling as currently used by Gnuplot as part of the standard options of Graph/Gnuplot.pm. Added global options for input and output to support syntax as Gnuplot implements date/time. Included details on date/time handling in documentation.
• Graph/Xmgrace.pm
  1. Fixed the handling of data options that were lists of options. This made the bar charts options work correctly among other options.
  2. fixed DESTROY error that prevented this module from running under Perl 5.6.
  3. fixed bug that prevented column data entry format from working.
  4. fixed bug that caused the test run for Xmgrace to fail even if the run of the Xmgrace application was a success.
  5. Updated syntax in Xmgrace.pm to run consistently under Perl 5.6
  6. Created a new hash to handle options of Xmgrace that consist of lists of options and provided new infrastructure for checking user choices against lists of options.
  7. Cleaned up the way internal errors where handled.
  8. Replaced out of date and awkward html documentation with Perl standard POD documentation.
• Graph/xrt2d and Graph/xrt3d
  1. fixed bugs that resulted in the path location of xrt binaries not being stored in a place where Perl wrapper could subsequently retrieve it.
  2. Replaced out of date and awkward html documentation with Perl standard POD documentation.
  3. Fixed bugs in the way global symbol spaces where used so that paths to various applications weren't lost between subroutine calls.
  4. Added support to Graph/xrt3d to read data from a file instead of a matrix.
  5. Changed the way images were converted from one raster format to another. Changed Graph/xrt2d and Graph/xrt3d to use either Imagemagick or Netpbm for making image conversions. Expanded the number of supported image formats to include: Postscript, X-window (xwd), JPEG, and PNG.

• Graph/Xmgrace.pm
  1. completed preliminary release version

1999-08-26 Esmond Lee <e3lee@ipn.caida.org>

• Graph/Gnuplot.pm
  1. setting $Chart::Graph::debug = 1 now increases debug messages
  2. setting $Chart::Graph::save_tmpfiles = 1 now preserves temp files

1999-05-21 Michael Young <mhyoung@ipn.caida.org>

• Graph/Gnuplot.pm:
  1. added option to print out default x2y2 tics
  2. setting $Chart::Graph::debug = 1 now preserves temp files

1999-04-26 Michael Young <mhyoung@ipn.caida.org>

• Graph.pm (\$xvfb):
  1. made a working test suite
  2. all distribution files are in place
  3. many bugs have been fixed

1999-04-19 Michael Young <mhyoung@ipn.caida.org>

• Graph.pm :
  1. fixed bug with $ENV{TMPDIR} being overwritten
  2. split Graph.pm into Chart::Graph, Chart::Graph::Utils, Chart::Graph::Gnuplot, Chart::Graph::Xrt3d
  3. fixed typos in documentation

1999-04-05 Michael Young <mhyoung@ipn.caida.org>

• Graph.pm :
  1. added POD documentation to the end of file
  2. using $VERSION = 1.0 for the first release.
  3. made updates to documentation

1999-03-31 Michael Young <mhyoung@ipn.caida.org>

• Graph.pm : This is the first entry in the changelog.
  1. added /usr/dt/lib to LD_LIBRARY_PATH for the xrt binary "graph". graph has rouble finding libMrm
  2. now searches environment variable TMPDIR for a place to store temporary files. Will default to "/tmp" if TMPDIR is not defined.
  3. fixed bugs in programs not found in the search path i.e. Graph.pm will only search for programs needed by gnuplot if gnuplot() is called. It will exit if a necessary program is not found.
  4. added missing calls to carp for abnormal exits.
