.SH "NAME"
CGI::Application::Plugin::DBIProfile::Graph::HTMLBarGraph \- If it weren't for HTML::BarGraph bugs, this would work.
.SH "DO NOT USE THIS"
.IX Header "DO NOT USE THIS"
This is provided because I had it done, and it provides another example, but there are bugs in HTML::BarGraph.
.PP
If HTML::BarGraph ever gets fixed, this will start to work correctly. The problem is its use of globals to track things like \f(CW$maxval\fR, which throws off scaling of the graph for subsequent calls to \fBgraph()\fR.
.SH "BUGS"
.IX Header "BUGS"
HTML::BarGraph is not mod_perl safe. It has globals that track, for instance, \f(CW$maxval\fR. That doesn't get reset accross calls to \fBgraph()\fR, so whatever your largest value graphed is, that will set the scale of all graphs to come.
Actually, it's not even single process safe... you can't make more than one call to \fBgraph()\fR.
