This is GIFgraph, a package to generate GIF charts, using Lincoln Stein's
GD.pm.
INSTALLATION
needed to install (also see TESTED PLATFORMS):
perl 5.004
GD > 1.14
to install:
perl Makefile.PL
make
make test
make install
NB: If you don't use the same version of GD that I have (1.18), some
of the tests may fail (specifically, the area test). You should be
able to ignore this failure, if the samples files give you good
results. IOW: Check the samples in the samples directory. If they look
good, then GIFgraph will work fine.
to see some samples:
cd samples
make
That should generate a set of gifs, which you can view using the HTML
pages in the same directory (or whichever other way pleases you).
The documentation available is contained in GIFgraph.pm, as pod.
The latest release should normally be available from CPAN and from
http://www.tcp.chem.tue.nl/~tgtcmv/perl/

MOST IMPORTANT CHANGES SINCE VERSION 1.01
- Vertical printing of X axis labels
- CHANGED DEFAULTS for zero_axis and zero_axis_only
- Fixed problems with negative values, data ranges without 0, and
printing of the x axis labels (I hope)
- No more support for perl 5.003. Since perl 5.005 is out, and I don't
have a 5.003 here to test all the time, I won't support it anymore.
MOST IMPORTANT CHANGES SINCE VERSION 0.91
- Legends
- Support for negative numbers
- Ticks for X axis
- line types and widths
- Allow entries in data set to be undef (to skip them)
- Changed 'zero' angle for pie charts (was right, now is front/bottom)
- Definition of colours now possible. See GIFgraph::colour::read_rgb
for details
- See file CHANGES for more
TODO
- 3d look for graphs
- logarithmic scaling
- numerical X axes
- Autoloading/splitting, etc
- More options, split up some options.
- Mixed Graphs
- Better preset options for certain graph types
BUG FIXES IN THIS VERSION
See file BUGS
NOTES FOR WIN32
GIFgraph installs and runs well under Gurusamy Sarathy's port of perl
for win32, and its usage is exactly the same as documented.
The ActiveState port for win32 can be used with Dave Roth's port of GD
for win32. This port, however has a peculiarity. It is impossible to
manipulate the gif data in memory (the GD::Image::gif() method always
writes to a file descriptor, instead of returning the data). This
makes the use of GIFgraph with that port impossible without a lot of
work.
This means that until someone ports GD for the ActiveState perl with
full support for all its functionality, GIFgraph will not work on
ActiveState's port.
