7 Oct 2000

- Addition of undefined data set colour.
- Addition of bar_width option
- Preparation of release 1.33

May - Sep 2000

- Various small bug fixes

7 May 2000

- Finalised code for value display
- prepared for release of 1.32

6 May 2000

- Added FAQ to distribution
- Fixed bug with calculation of bottom of plotting area (causing axis
  tick values to be cut off, when no label present)
- Some 5.004 code retrogression

30 Apr 2000

- Fixed problems with overzealousness of correct_width attribute for
  mixed charts (report Jimmy Sieben)
- Fixed problem with zero_axis and zero_axis_only drawing when y values
  are all on one side of 0 (report Matthew Darwin)
- Fixed GD::Graph::Data::get_min_max_y and ppoints charts with numerical
  X axes (thanks Peter)
- Fixed problem when data sets contain only zeroes (report Joe Pepin)
- Added experimental support for hotspots

15 Apr 2000

- Added some code (thanks Gary) to deal better with 'numerical' X axes.
- Prepared version 1.30 for release, mainly to make sure that patches
  that come in are done against the new code base

27 Feb 2000

- Added cumulate attribute, needs more code changes to fully replace
  'overwrite == 2'. For now, it will work.

20 Feb 2000

- Added correct_width option
- Fixed bug in pie. If one of the slices ended up at exactly 90 degrees,
  or very close to it, The fill would cause GD to core dump. Ugly.
  Introduced half a degree of relaxation there.
  There still are troubles with this. I really need to think of another
  way to do this.

15 - 17 Feb 2000

- Added Error class, removed error checking code from Data
- Added $VERSION to each module
- Fixed bug in can_do_ttf. Can now _really_ be called as static or
  class method.

14 Feb 2000

- Fixed bug in bar width. Removed some roundings, and always add 1
  to left boundary. Also, adapt r_margin on the fly to make sure bars
  are always exactly the same width. This changes the look of graphs
  slightly, but it looks so much better in general.
- Fixed bug in drawing of vertical x labels with x_tick_number enabled
- Cleaned up code in setup_coords in axestype.pm a bit

12 Feb 2000

- Removed ReadFile sub from GD::Graph.pm. I never got around to making
  it part of the interface anyway. replaced by GD::Graph::Data.
- Rewrote lots, and lots of code. General cleanup. Removal of direct
  work with data array. Now only works with interface of GD::Graph::Data
  object (hopefully)

09 Feb 2000

- Added GD::Graph::Data to distribution

27 Jan 2000

- Added patch from Hildebrand, which allows non-drawing of accents on
  bars with accent_treshold option
- Fixed rounding problems with overwrite == 2, alert from Hildebrand,
  also a patch supplied which couldn't be used because of other code
  changes related to sample17
- Added sample18, supplied by Hildebrand as illustration of rounding
  problem.
- Fixed off-by one error in pick_data_color whenever color pick is based
  on point instead of data set (cycle_clrs and pie)
- Added accent_treshold option to area charts

09 Jan 2000

- Rewrote some documentation to reflect new GD::Text behaviour.

08 Jan 2000

- Rewrote set method to only accept documented attributes.
- Made sure all documented attributes are part of the %Defaults hashes.
- Changed inheritance slightly, because changing the set method and
  using access to file scoped variables didn't work very well with
  multiple inheritance in mixed and linespoints. All file scoped
  material now is kept in the common ancestor of these, i.e. axestype.

06 Jan 2000

- Added shadow patch from Jeremy Wadsack, changed a few things: Allow
  negative shadows, move his code out a bit more.
- Added color cycling patch from Jeremy. Adapted it to new code, and
  added code to also allow cycling of colour of bar borders.
- Documentation.

05 Jan 2000

- removed all references to perl version from any code. Leaving it up to
  users to find out for themselves. They'll just need to read the
  documentation.
- Applied patch from Jeremy Wadsack fixing text sticking out of pie
  slices causing fills to fail.
- cleanup of code in pie.pm: draw_data, filling front of pie, and
  _get_pie_front_coords.

03 Jan 2000

- Fixed two_axes and negative values
- released 1.22

Dec 1999, mgjv

- Development and support back to me, mgjv. GIFgraph and Chart::PNGgraph
  (hopefully) will both become wrappers around this new set of modules.

- Renamed to GD::Graph
- Removed direct font handling stuff, and moved font handling to
  GD::Text::Align objects
- Removed methods for writing to files directly. it is now up to the
  user of the module to save the image to a file. GIFgraph and
  Chart::PNGgraph will still do this
- plot method now returns a reference to a gd object, no longer the
  image data. GIFgraph and Chart::PNGgraph still exhibit old beahviour.
- Added some new options, and split up some others. 
- Added new methods, mainly to detect the useability level of the
  current GD.
- Changed any die and warn statements to croak and carp

Thu October 21 1999 by sbonds@agora.rdrop.com
- Chart::PNGgraph version 1.13
- Added primitive support for TrueType fonts
- Fixed bug where 3d charts with very large slices would not have both
  parts of the front filled properly.

Thu October 7 1999  by sbonds@agora.rdrop.com
- Chart::PNGgraph version 1.12
- Changed namespace to Chart:PNGgraph so that CPAN will index it properly
- Added "base" tests-- still very incomplete
- Changed sample 5-2 to have multiple lines since this is what the html
  file described it as having.
- Checks the read-only attributes 'pngx' and 'pngy' so these will not get
  accidently set.  $g->set() returns undef if they are present, but the
  rest of the attributes will be set.

Tue August 31 1999  by sbonds@agora.rdrop.com
- Please contact me rather than the original author for problems unless
  you are convinced that the problems are not a result of the port to PNG
- Converted GIFgraph-1.10 to PNGgraph-1.10 so it works properly with GD-1.20
- UNISYS has been increasingly defensive of the LZW patent used in GIF
  compression, which necessitates these kinds of fixes.  

Tue August 25 1998

- Fixed bug with undef values for first value in lines graphs
- Changed one or two samples, and samples Makefile dependencies

Tue August 25 1998

- Added bar_spacing option.
- Fixed a slight drawing 'bug' while doing that.
- Changed a few of the samples to use bar_spacing
- Implemented numerical X axis, based on a changed axestype.pm from
  Scott Prahl <prahl@ece.ogi.edu>. many thanks.
- Added sample54 to illustrate

Tue August 18 1998

- Added rudimentary mixed type graph

Mon August 17 1998

- Added control over axis label placement through x_label_position and
  y_label_position.
- Added possibility to call a coderef to format the y labels. See
  y_number_format.
	(Idea: brian d foy <comdog@computerdog.com>)
- Fixed some bugs (see file BUGS, version 1.04)

Fri August 14 1998

- Uploaded version 1.03 to CPAN

- Finally able to make some fixes
- Changed defaults for zero_axis and zero_axis_only to 0. Were both 1.
  Needed to do this, because of all the confusion they cause
- Test for defined $s->{y_(min|max)_value} 
	(Honza Pazdziora <adelton@informatics.muni.cz>)
	(Vegard Vesterheim <vegardv@runit.sintef.no>)
- Fixed handling of negative values (I hope)
	(brian d foy <comdog@computerdog.com>)
- From now on, require 5.004. 5.003 is dead, and should be deprecated
  now that 5.005 is out.
- Added 5.005 specific MakeMaker fields to Makefile.PL

Tue May 12 1998

- Cleaned up a bit, finalised version 1.02, because of time
  contraints, and the need to get these bug fixes out. Didn't succeed.

Mon Jan 19 1998

- Fixed some bugs (see file BUGS, version 1.02)
- Added option x_all_ticks, to force all x ticks to be printed, even
  if x_label_skip is set.
- Added option x_labels_vertical, to print x labels vertical
	(Thanks to DBelcher <dbelcher@cyberhino.com> for a patch)
