How to use this builder:
Here is a screenshot of the builder at design time:

Page Location	Page location where tag cloud should be displayed
Color of Maximum Value	Hex value of color for maximal value. For example #000000 for black
Color of Minimum Value	Hex value of color for minimal value. For example #aaaaaa for light grey
Relative minimal Font size	Relative Font size of the minimal value displayed in the cloud. Enter a percent value without the percent sign.

Width of displayed cloud	Width of the coud in pixel. For example 200.
Heigth of displayed cloud	Approximate heigth of the cloud in pixel. The height itself will be calculatetd with a best effort during generation.
Element variable with tags	Variable of the element which holds the tags. For example Variables/myvar/rows/row/tagname.
Element variable with weigth	Variable of the element which holds the tags. For example Variables/myvar/rows/row/weigth.
Minimal weight to display	Minimal weight a tag should have before it is displayed in percent. for example 40
Action for selected link	Action which should be called when clicking on a link.

Remarks:

• Element variable with tags needs to be an element and not an attribute.
• Element variable with weigth needs to be sibling of the Tag variable.
• Element variable with tags / with weigth : Here the variable needs to be entered without the ${ in front and } at the end. You can enter a indirect value here. but the result needs to be a name of a variable which can be found in the webApp. for example you can enter Variables/myvar/rows/row/${columnname}. In this case case columnname should be a string variable which holds the name of the column.
• Action needs to be set. Can be an empty action wich points back to the page.

Attached you find the builder itself and a TagCloud widget which uses the builder.
