Well I ventured in to the code and made a couple of changes and now have it working along with two nice features:
sort:
"numasc" ascending number of counted Tags
"numdesc" descending number of counted Tags
top:
List the top number of tags found. Useful when with above sort.
Example:
[!TvTagCloud? &parent=`132` &landing=`132` &sort=`numdesc` &top=`10`!]
Snippet Code:
<?php
/****************************************************
* Name: TvTagCloud
* Version: 2.1.2
* Desc: Displays the tags from a documents tvar in a "tag cloud"
* Credits:
* Created by Kyle Jaebker and optimized by Mark Kaplan
* Style code added by Garry Nutting
* Large parts refactored and features added by Nick Crossland
* dittoID added by Jens Weintraut
* Based of code by Marc Hinse, [email protected], www.modxcms.de (original TagCloud creator)
*
* Usage: [!TvTagCloud? &parent=`1` &landing=`22` &tvTags=`docTags` &showCount=`1`!]
*
* Parameters:
* parent: folder that conatins the documents which are to be counted. Can take a comma separated list of parents
* depth: the number of levels down we should search for child documents
* days: the number of days to look back over to find tags. Leave as 0 for all time
* min: minimum number of tag occurances for tag to show, 0 for all
* sort: how should the results be ordered? By default they will be sorted by document ID. Values can be "asc", "desc" or "random"
* landing: id of document to display ditto listings
* tvTags: the template variable that has the tags
* tagDelim: delimiter between tags in tvar
* displayType: [cloud | list] output as a tag cloud or an unordered list
* showCount: if you want the number of occurances to be displayed set to 1
* caseSensitive: if you want tag duplicate removal to be case sensitive set to 1
* steps: comma separated list of the numeric intervals to determine the size of the tag class
* styles: comma separated list of class names that will be applied to each of the size intervals in "steps"
* tooltip: Template for the tooltip that will appear as the title attribute for each tag link. Takes placeholders [+count+] and
* [+tag+] which will be replaced with appropriate values
* dittoID: Id of the Ditto instance which should display the selected tag
*
* HACK:
* top: number of restricted entries to display
*
*Landing Page setup:
* the landing page should have a call to ditto (the latest version) with at
* minimum the following tagging parameters set:
*
* [!ditto? &startID=`1` &tagData=`tvdocTags` &tagDelimiter=`,`!]
*
