That should show everything required without having to wrestle with the vagueness of a 3D perspective.Unknownhttps://www.blogger.com/profile/10465719514727931699noreply@blogger.comtag:blogger.com,1999:blog-4407602959869119653.post-73046590232856629022009-12-22T13:49:36.106+00:002009-12-22T13:49:36.106+00:00Interesting visualisation, there are obviously som...Interesting visualisation, there are obviously some characteristic trends coming out - however using pseudo-3D Excel graphs is flawed at best. For example, on the top graph, what are the values for under-20s between midnight and 6am? They might be high but obscured by the 20s-30s data. Obviously just a quirk of the 3D graph in thie case, but for more controversial data, cynical people might think there's potential for deliberate bias, or hiding undesirable data to reinforce a hypothesis.<br /><br />Using small multiples would not be hiding any values or giving undue prominence to other data and therefore would be "fairer". Do you know Tufte's seminal work "The Visual Display of Quantitative Information", which goes into great detail about this kind of thing? <br /><br />Of course, it takes a lot more time to set up small multiples than just pile everything into a pseudo-3D graph!<br /><br />By the way I think the borough is Westminster.Olliehttps://www.blogger.com/profile/16101185101622046547noreply@blogger.com
