Chart-PNGgraph - Changes

Sat April 8 2000 by sbonds@agora.rdrop.com - Chart::PNGgraph version 1.21
- Minor fix of a bug in sample11.pl

Thu April 4 2000 by sbonds@agora.rdrop.com - Chart::PNGgraph version 1.20
- Major revision from Martien Verbruggen to use GD::Graph instead of linking directly with GD. This is intended for backward compatibility only-- you are encouraged to use GD::Graph instead of Chart::PNGgraph as there will not be any more features added to Chart::PNGgraph

Mon January 3 2000 by sbonds@agora.rdrop.com - Chart::PNGgraph version 1.15
- minor bugfix-- 'make test' would fail due to a missing file

Mon December 20 1999 by sbonds@agora.rdrop.com - Chart::PNGgraph version 1.14
- Bugfixes only-- better TrueType support coming soon - Fix divide-by-zero error when all data points are zero - Clarify documentation on how to use plot(\@data) method

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)

Fixed some bugs (see file BUGS, version 1.01)
Added formatting for y labels (option y_label_format)

Added read_rgb to PNGgraph::colour to allow definition of own colours
Added t/colour.t
Removed a lot of unnecessary quotes all over the place

Mon Dec 22 1997

Center graph titles on axes, not on png
Added line types
Moved initialise() to each module with $self->SUPER inheritance
Added check for duplicate GD::Image object initialisation
Added binmode() to t/ff.pl to make tests compatible with Win32 platforms (D'OH).

Thu Dec 18 1997

Allow undef values in data sets, and skip them
Added prototyping of functions
Legends, finally requests from Petter Reinholdtsen <pere@link.no>
Giorgos Andreadakis <gand@forthnet.gr>
