Hi all.
I wonder if i can create a region based on some sort of tree like chart. For example:

This would be based on a query on a master / detail or hierarquical relationship. Notice a color can be set based on a condition for a ocurrence. Is this possible?
I think i've seen this before, but can't remember pretty well where...
If anyone thinks this is possible or provide an URL for checking would be extremely unvaluable!!!.
Thanks in advance!!!
OK... Found it... It is on Sample Charts Application as a plugin. But there is still one question: How do I set the colors based on a value????
