Hello Uwe,

Sorry to publish on this old post, did you have found a solution to have a 
cloud tag with bigger pills ? Just try Stephan code but don't work for me.


Cheers
Sylvain

Hallo Stephan,

I'm a bit late, but: thanks! It works! At least with counts up to 9 :-)

The missing parts for a real tag cloud implementation are AFAICS:
1) get min and max count over all tags (minCnt, maxCnt)
2) fit each count (cnt) into a corresponding font size range (minFontsize, 
maxFontsize):
fontSize = minFontsize + (cnt – minCount) * (maxFontsize – minFontsize) / 
(maxCount - minCount)

So much for the theory. Implementation is left as an exercise for the 
reader :-)

Uwe

 I just created a count filter which WOULD help with this, but your idea

 able to tell the difference? ;)

 For completeness sake, this is the source of my count filter:

 /*\
 title: $:/core/modules/filters/count.js
 type: application/javascript
 module-type: filteroperator

 Filter operator that gives the counts the current list's members

 \*/
 (function(){

 /*jslint node: true, browser: true */
 /*global $tw: false */
 use strict;

 /*
 Export our filter function
 */
 exports.count = function(source,operator,options) {
 // count the source if it's not an array
 var count = 0;
 if(!$tw.utils.isArray(source)) {
 $tw.utils.each(source,function(element,title) {
 ++count;
 });
 return [  + count ];
 }
 // return array's length
 return [  + source.length ];
 };

 })();



 used like this (using your request)

 \define mySize()
 font-size:$(cnt)$em
 \end

 $list filter=[tags[]!is[system]sort[title]]
   $set name=title value={{!!title}}
 $list filter=[is[current]tagging[]count[]]
   $set name=cnt value={{!!title}}
 span style=mySize
   $tiddler tiddler=title
 $transclude tiddler=$:/core/ui/TagTemplate/
   /$tiddler
 /span
   /$set
 /$list
   /$set
 /$list



 I'm not sure yet, whether to make it a plugin. Comments welcome.

I don't think it's possible yet.
