The Summary widget is great for getting a quick summary of numeric fields for all features in the current map display. Or, you can specify a field in your feature layer to filter on and return a summary for individual features. But, does anyone know how to return a summary on a group of selected features within the current map display? I have a series of survey polygons (all in the same feature layer) in my map and I would like to be able to select a group of discrete surveys and return summary statistics on just those surveys. This may require a custom version of the Summary Widget and I was wondering if anyone was working on such a custom widget?
