Summary0000613: Anime Stats - History Graphs Broken for some anime
Description[ Problem ]

Was trying to view the Status History for 'Fushigi na Koala Blinky'
Anime Page: http://anidb.info/a4208
Stats Link: http://anidb.info/perl-bin/animedb.pl?show=animehist&aid=4208

Both History Graphs/Objects do not show up and it complains:
-------------------------------------
XML Parsing Error: syntax error

Location: http://anidb.info/perl-bin/animedb.pl?show=animehist&aid=4208&gfx=users

Line Number 1, Column 1:Content-type: text/html

Other titles that have these issues can be found as 'Additional Information'.

It may be useful to take note of the 'Useful Exception'.



The problem maybe when the graph is being scaled? (see Useful Exception)

Well, probably obvious when you take a look at the code and the samples above.

Heres the real issue:

<html><body><h2>ERROR:</h2>
<h4>Illegal division by zero at /usr/local/share/perl/5.8.4/SVG/Graph/Glyph/line.pm line 25.
</h4></body></html>
-----------------------------------------------------

I took a look at SVG Graph for the hell of it:
This is probably it:
sub draw{
   my ($self,@args) = @_;

   my $id = 'n'.sprintf("%07d",int(rand(9999999)));
   my $group = $self->svg->group(id=>"line$id");

   my $xscale = $self->xsize / $self->group->xrange;
   my $yscale = $self->ysize / $self->group->yrange;

So when you pass data such that the x and or y range are 0?... my guess is 0..0 1..1?

(Sorry, I forgot a '/' in my pre tag of the Description. -_- )
