George,

If you want the center of the map then you use

map.extent.getCenter()‍

map.geographicExtent.getCenter()‍

if it is the center of the graphics you are adding then you will use

graphicsUtils.graphicsExtent(yourArrayofGraphics)‍

Sorry I'm new to the use of this API.
and I have the heart to my map, now I need is to know the zoom level so that all points are shown on the map.

I'm using this map.centerAndZoom (point, zoom);

George,

There is a time to use centerAndZoom but what you described would better be using by setting the maps extent using

map.setExtent(graphicsUtils.graphicsExtent(yourArrayofGraphics), true);‍
