You're in luck Bo. I needed to do this today too so I pulled together the logic from various samples (yes, I hate reinventing the "wheel"):
private function zoomSelected():void
{
if (graphicsLayer.numGraphics > 0)
{
var pt:MapPoint = new MapPoint();
var extSelected:Extent;
for each (var selgra:Graphic in graphicsLayer.graphicProvider)
{
pt = getGeomCenter(selgra);
//Calculate the Selected Feature Extent
if (extSelected == null) {
extSelected= new Extent(pt.x,pt.y,pt.x,pt.y);
} else {
if (pt.x > extSelected.xmax) {extSelected.xmax=pt.x;}
if (pt.y > extSelected.ymax) {extSelected.ymax=pt.y;}
if (pt.x < extSelected.xmin) {extSelected.xmin=pt.x;}
if (pt.y < extSelected.ymin) {extSelected.ymin=pt.y;}
}
}
}
map.extent= extSelected.expand(2);
}
