<!-- This sample shows the usage of the slicePlotItem() method. -->
<div id="indicatorDiv">Method Name: <strong>slicePlotItem()</strong>

    <p>Slices in/slices out a pie/doughnut slice.</p>
    <p>When a pie-slice is selected from the drop-down given below, the corresponding slice on the pie chart is sliced out. Because multi-slicing has been disabled in the JSON chart data, when one slice is sliced out, the previously sliced out slice is sliced in.</p>
    
        <div class="text-center">
