Feature Partially Obscured after Zoom to Extent

MattFancher

I use the following to zoom to a selected feature:

var feature = fset.features[0]; myMap.graphics.add(feature); myMap.setExtent(feature.geometry.getExtent());

Which works, but sometimes the feature is partially obscured by the limits of the map div.  For example, in this map:

http://maps.puc.state.oh.us/exchange/index.asp

If you select "Aberdeen" from the drop down, then the zoom works as I'd like.  If you select "Adamsville", then you'll see what I'm talking about.

Any suggestions to fix that?  Thanks in advance!

I see what you mean. Here are some thoughts though I am sure there are numerous other solutions out there:

1) setExtent(extent, fit?) note that there is fit? option. If you are using Tiled layers then maybe this would help?  Not sure, never really used this option.  Here is the documentation:
http://help.arcgis.com/en/webapi/javascript/arcgis/jsapi/map.html#Map/setExtent
NOTE: read the documentation on this. I am not sure if I am correct on my assumption of the fit? param.

2) Generally, I like to expand the extent so that it gives the map a little room/margin around your selected feature.
map.setExtent(extent.expand(expandFactor));

3) Never tired this but it looks like other features beside the one that you pointed out had issues with zoom scale. Try seeing with the following will do for you.
esri.geometry.getExtentForScale(map, scale)
