well, adding the following method works (but not with the NumberFormatter):
...
return data.Expense + newline + round(percentValue,2) + "%";
...
function round( num, precision ) {
num = "" + num
var fullNum = "" + Math.round( num* Math.pow( 10, precision ) );
var decPoint = fullNum.length - precision;
var result;
if( decPoint != 0 )
{
result = fullNum.substring( 0, decPoint );
result += ".";
result += fullNum.substring( decPoint, fullNum.length );
}
else
{
result = fullNum;
}
return Number( result );
}
The function "round" was lifted entirely (and unchanged) from an
ActionScript blog that I googled on:

Subject: [flexcoders] percentage value precision
I'm using a display function to show percentage values in a pie
chart
(thanks to the earlier suggestion from this list), as follows:
function display(data, field, index, percentValue) {
return data.Expense + ": " + percentValue + "%";
}
Now what I'd like to do is have the percentValue returned with a
precision
of only two points past the decimal. I can set this up with a
NumberFormatter, but what is the syntax for putting it into action?
