If you want to create a pie chart with exploded slices, set the perWedgeExplodeRadius attribute in <Pie2DSeries> ( or <Pie3DSeries> ). In the above sample chart, the 5th slice is set to be exploded when the chart is created ( perWedgeExplodeRadius="[0,0,0,0,0.1]" ).

...
<Pie2DChart showDataTips="true" explodingAlone="false" >
...					
  <Pie2DSeries nameField="Country" field="Export" perWedgeExplodeRadius="[0,0,0,0,0.1]" labelPosition="inside" formatter="{numFmt}" color="#ffffff">
  ...
  </Pie2DSeries>
...
</Pie2DChart>

<Pie2DChart>

explodingAlone The explodingAlone attribute determines whether or not to explode only one slice when a slice is clicked. This attribute is valid only if explodable="true" ( The default value of the explodable attribute is "true" ).

<Pie2DSeries>

perWedgeExplodeRadius The perWedgeExplodeRadius attribute determines whether or not to explode slices when the chart is created. e.g. if you want to create a pie chart with exploded 2th and 7th slices, then you need to set as perWedgeExplodeRadius="[0, 0.1, 0, 0, 0, 0, 0.1]".
