I slightly modified the formula to take in account min of values like <code>int((pmax - pmin) * (log(x - vmin)) / (log(vmax - vmin)) + pmin)</code> and filter out situations like log(0) and log(1) . Take a look at Blogoforum clouds now! If you can, please tell us how did you get to that formula.

Here you go: Let's say you want your your tags in sizes from 1 to 10, according to their counts. I'll use pseudocode here. You define boundaries: pmin <- 1 pmax <- 10 Then you calculate the min and max values from your tags: vmin <- min(values) vmax <- max(values) Now, let's say you have a tag with 'x' occurences. The log-size of your tag is: int((pmax - pmin) * (log(x)) / (log(vmax)) + pmin) - 1 reply Mon, 18 Sep 2006 03:14:39 GMT http://blogoforum.com/tag/blogoforum+math+sizes+suggestion+tagcloud+tagging/re-tag-cloud-makeup-continued-3320.html http://blogoforum.com/tag/blogoforum+math+suggestion+tagcloud+tagging/tag-cloud-makeup-continued-3294.html Thanks Automatthias for the suggestion! Blogoforum now filters the least important tags. Please tell me where I can read about how to apply a logarithmic function to the tag sizes. - 1 reply Sun, 17 Sep 2006 19:19:39 GMT http://blogoforum.com/tag/blogoforum+math+suggestion+tagcloud+tagging/tag-cloud-makeup-continued-3294.html http://blogoforum.com/tag/blogoforum+tagcloud+tagging/re-tag-cloud-makeup-3080.html What I dislike about current tagclouds is that there is ONE HUGE TAG, and 90% of the remainig tags are very small. It looks like the cloud is 90% trash. I suggest: - Filtering out the least frequent tags - Applying a logarightm function to the tag sizes. It will reduce the graphical domination of the most frequent tags. I did it with my project: http://automatthias.wordpress.com/2006/07/26/size-and-color/ and it works fine. - 2 replies Sun, 17 Sep 2006 09:27:13 GMT http://blogoforum.com/tag/blogoforum+tagcloud+tagging/re-tag-cloud-makeup-3080.html
