Flex - zoom to point

RobertMyers

The code below will zoom the expand extent of a selected Graphic. I don't understand what the equivalent would be if the Graphic is a point. The point would be selected and zoomed to with a certain extent beyond the location of the point.


  
   private function zoomToRow(graphic:Graphic):void           
   {               
    var offset:int=300;
    var graphicsExtent:Extent;
    if (graphic){
     graphicsExtent = graphic.geometry.extent;
     graphicsExtent.xmax=graphicsExtent.xmax+offset;
     graphicsExtent.xmin=graphicsExtent.xmin-offset;
     graphicsExtent.ymax=graphicsExtent.ymax+offset;
     graphicsExtent.ymin=graphicsExtent.ymin-offset;
     myMap.extent = graphicsExtent
     // make sure the whole extent is visible
     if (!myMap.extent.contains(graphicsExtent)){
      myMap.level--;
     }        
    }
   }

Robert,

    This is esri's new way of handling zooming to point data

// Zoom to 1/16th the size of the current extent.
                        // This is the same as calling map.zoomIn() four times.
                        map.zoom(1 / 16, mapPoint);
