There isn't much documentation, but it's simply a boolean expression - if it returns a non-zero value, the pie slice will be popped out. For example:

if (Country='US', 1, 0)

The slice for US will pop out of the pie.

Try a simple expression =1, and all the slices will be popped up, except for "All Others"

Hi Grahum,

Pie popout only works for pie charts. You might want to look at show value rather, but I'm not sure you will be able to get the desired effect. Is there anything preventing you from using the popup window on mouse hover over?

Do you have sample data/app to be able to work on and test?

You can create an expression using function DUAL - the number within the Dual() will determine the plotted values, while the text will be displayed as a "Value on Data Point". You can then condition the display of your values on data points using another attribute "Show Value", which is also a Boolean expression - every time it renders a non-zero value, the text will be displayed.
