Zooming to ArcGIS JavaScript API graphic feature, but not to full extent?

Question

I have a Python based geoprocessing service that gets called in my web app. The web app takes a few input parameters, and zooms to a returned buffered section of cable that meets the criteria. This all works really great.

I'm using the following code to zoom to the returned graphic feature:

map.setExtent(graphicsUtils.graphicsExtent(map.graphics.graphics));

But, I really don't want the map to zoom this close to the graphic:

No

I'd prefer something like this:

Yes

• PolyGeo: In Python I would do something like df.extent = df.extent * 2.5 so I'm guessing map.setExtent = map.getExtent * 2.5 (with no JavaScript knowledge claimed).
• ianbroad: Thanks for the suggestion. I just tried map.setExtent(graphicsUtils.graphicsExtent(map.graphics.graphics) * 2); but it doesn't seem to like it.

Answer 1

In the Extent class there's an expand(factor) method:

enter image description here

So, I tried:

var extent = graphicsUtils.graphicsExtent(map.graphics.graphics).expand(4)
map.setExtent(extent);

And it's exactly what I wanted.
