Bargraph version 2.40 Release Notes

New

1. Everything is now in Makefile.PL format.
2. Executable is now called 'bargraph' instead of 'bargraph.pl'.
3. All documentation is in POD. All modules have POD.
4. Man pages and WWW documentation is built from POD.
5. Added ISOLatin1 support.
6. Added -f option so defaults file doesn't have to be called .bargraph.
7. Make create_from_options() accept a string instead of a filehandle to make it easier to dynamically create bargraphs.
8. Add new Key options to horizontally lay out keys.
9. Add -clipmin and -clipmax Axis options.

Bugfixes

1. Fixed bug where -setmin didn't work for minimums < 0.
2. The -climpin/-clipmax get rid of some technically correct, but very ugly looking graphs for axes with a non-zero minima.

Notes

Bargraph will not work with recent versions of GD. Bargraph uses GD to create GIF output, and GIF support was removed from recent versions of GD for copyright reasons. I haven't yet figured out another way to create GIF files, and I don't even know if it's possible for me to do legally. If you have GD-1.18 installed, GIF generation will work. I suggest, though, that you generate your graphs in PostScript format and use other tools for format conversion.

ISOLatin1 support is in bargraph-2.40, but it has not been tested. I folded in some ISOLatin1 code that was contributed by users. It does not appear to work for me, but I know almost nothing about foreign alphabets, so it may just be that my PostScript fonts aren't set up correctly or something like that. Please let me know if you have any problems or suggestions relating to this.

I have not fully resolved what bars should look like when the x axis of the graph is not drawn at zero. Some of the new options will help, but I'm still not satisfied with it. I may change some of how this works in the next revision. I would appreciate any comments.
