[Graph-dev] Suggestion for Chart::Graph::Utils.pm

[Etienne Goyer]

Hi,

Thanks for your Chart::Graph module.  I am using them to build a CGI
application that plot the output of iostat and sar.

/usr/lib/perl5/site_perl/5.8.0/Chart/Graph/Utils.pm line 161 read:

print "Set $count of tmp files are in $tmp_dir\n";

I believe that :

warn "Set $count of tmp files are in $tmp_dir\n"; 

would be more appropriate since it would not clobber STDOUT.  This is
very important with CGI script otherwise it could make Apache barf with
"Premature end of script headers" if you executed gnuplot() before you
send your header.

Again, than you very much for your modules !
