since the bugzilla upgrade I can no longer produce graphical reports for the "Change over time - new Charts". fex: http://tinyurl.com/ynadfm The image to be produced is replaced by its alternative text "Graphical report results".
your chart link is defective. If you go to that page, and look in the HTML src, and grab the image link. Throw it in your browser, and look at it as HTML, not an image. You get this error reported: undef error - DBD::mysql::db selectrow_array failed: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ')' at line 1 [for Statement "SELECT MIN(series_date) FROM series_data WHERE series_id IN ()"] at Bugzilla/Chart.pm line 223 Bugzilla::Chart::readData('Bugzilla::Chart=HASH(0xd736e59ffb0)') called at Bugzilla/Chart.pm line 204 Bugzilla::Chart::data('Bugzilla::Chart=HASH(0xd736e59ffb0)') called at data/template/template/en/custom/reports/chart.png.tmpl line 50 eval {...} called at data/template/template/en/custom/reports/chart.png.tmpl line 50 eval {...} called at data/template/template/en/custom/reports/chart.png.tmpl line 16 Template::Provider::__ANON__('Template::Context=HASH(0xd736ea9ef60)') called at /usr/lib64/perl5/vendor_perl/5.8.8/x86_64-linux/Template/Document.pm line 155 eval {...} called at /usr/lib64/perl5/vendor_perl/5.8.8/x86_64-linux/Template/Document.pm line 153 Template::Document::process('Template::Document=HASH(0xd736f0ef610)', 'Template::Context=HASH(0xd736ea9ef60)') called at /usr/lib64/perl5/vendor_perl/5.8.8/x86_64-linux/Template/Context.pm line 350 eval {...} called at /usr/lib64/perl5/vendor_perl/5.8.8/x86_64-linux/Template/Context.pm line 320 Template::Context::process('Template::Context=HASH(0xd736ea9ef60)', 'Template::Document=HASH(0xd736f0ef610)') called at /usr/lib64/perl5/vendor_perl/5.8.8/x86_64-linux/Template/Service.pm line 97 eval {...} called at /usr/lib64/perl5/vendor_perl/5.8.8/x86_64-linux/Template/Service.pm line 94 Template::Service::process('Template::Service=HASH(0xd736ea5a0f0)', 'reports/chart.png.tmpl', 'HASH(0xd736ea0d8d0)') called at /usr/lib64/perl5/vendor_perl/5.8.8/x86_64-linux/Template.pm line 71 Template::process('Bugzilla::Template=HASH(0xd736e9daa60)', 'reports/chart.png.tmpl', 'HASH(0xd736ea0d8d0)') called at /var/www/bugs.gentoo.org/htdocs/chart.cgi line 279 main::plot() called at /var/www/bugs.gentoo.org/htdocs/chart.cgi line 122
