Tree Map

Hello

I'm completely begginer and english is not my native language. I'll try my best to explain.

I was testing a tree map with gradient colors according to sum of sales. The thing is when I click in one of the segments I put on group, the others fade away and even typing Esc it doesn't get back to normal. Is that normal with tree maps? 

The other graphs I tried I just type esc and it gets back to original form.

Here is how it looks after I click in one of the segments and it remais like that after typing ESC.

Appreciate if any comments on this

Thanks

Michelle
