File talk:Measles incidence and vaccination England & Wales 1991-2007.png

This graph refers to measles incidence (i.e. numbers of cases per year), however the data source is for notifications. Notifications refer to suspected cases, which still need to be confirmed by clinical testing. Compare to the confirmed cases from the same source. --GenericBob (talk) 09:22, 8 May 2010 (UTC)[reply]

Whatever ends up replacing this file, there needs to be a key provided in the graph to identify the data. It might also be helpful to make one line dashed and the other solid, too. — Scientizzle 17:18, 14 May 2010 (UTC)[reply]

Has anyone informed the original poster that his graphic is impossible to properly interpret without a key? The source information says that he created it himself so it could be innacurate without a link to the study. Ambiesushi (talk) 15:49, 5 July 2012 (UTC)[reply]
