I tried to reproduce the problem, but to no avail - the tooltip of the column chart is correctly rendered in IE 9 (check this short screencast capture
). For your convenience I attached my test page, could you please edit it to show me your current implementation? This way I would be able to investigate what exactly is going on and provide concrete recommendations. Thank you in advance.
