coincident points - extent

PeggyCorey

I need to check for coincident points being returned from a FindTask, in order to zoom to the proper extent.  I am currently zooming using a centerAndZoom for single points, and using a setExtent for lines, polygons and multiple points.  But this will not work properly if the results set is a pair of coincident points, for example.  Below is a sample of my current zoom code, but I need a solution for this coincident point scenario. 

Anyone solved this kind of problem? 

Thanks!

if (graphictype == "point" && map.graphics.graphics.length == 1) {

  map.centerAndZoom(map.graphics.graphics[0].geometry,20);

}

else {

  var extent = esri.graphicsExtent(map.graphics.graphics);

  map.setExtent(extent.expand(2), true);

}

Peggy,

  Try something like this:

if (graphictype == "point" && map.graphics.graphics.length == 1) {
  map.centerAndZoom(map.graphics.graphics[0].geometry,20);
} else if (graphictype == "point" && map.graphics.graphics.length > 1 && !esri.graphicsExtent(map.graphics.graphics)){
  map.centerAndZoom(map.graphics.graphics[0].geometry,20);
} else {
  var extent = esri.graphicsExtent(map.graphics.graphics);
  map.setExtent(extent.expand(2), true);
}
