How to change pie slice percentage decimal places

mmarc442

Generating a pie chart. Slices have displayed percentages of 35.71%, 1.79%, 14.29% etc.
How do I change it to display 36%, 2%, 14%, etc. ?

You could use Math.round() in the beforeDrawDataPointLabel() like this<br />
<br />
<pre class='_prettyXprint _lang-auto _linenums:0'>function beforeDrawDataPointLabel( dph, label, icsc )
{
var oldValue = new String(label.getCaption().getValue());
var newValue = parseFloat(oldValue);
newValue = Math.round(newValue);
var newCaption = newValue + "%";

label.getCaption().setValue(newCaption);
}
</pre>
