Highlighting a pie chart slice

madhavil

Hi Every one,

Any body has some idea on highlighting a pie chart slice based on some criteria?
We have a pie chart that displays the quantities of products. And then the report also displays some more details of a single product selected by user(from a drop down).
Now my requirement is for the selected product the corresponding slice in the pie chart should be highlighted with some differentiation from other slices.
Please suggest a solution.

Thanks & Regards,
Madhavi.

You could do this one of two ways, you can either explode the slice that matches the parameter chosen or you can remove all of the labels except for the parameter chosen. The example I attached removes all labels except for the country that was selected.<br />
<br />
I set the parameter value as a PGV in the initialize() of my report, then I recalled it in the beforeDrawDataPointLabel() using this script.<br />
<br />
<pre class='_prettyXprint _lang-auto _linenums:0'>
function beforeDrawDataPointLabel( dph, label, icsc )
{
var highlight = icsc.getExternalContext().getScriptable().getPersistentGlobalVariable("highlight");
if( label.getCaption().getValue() != highlight ){
label.setVisible(false);
}
}

</pre>
