¿ArcGIS.com admite etiquetas para campos de fecha en mapas?

Question

Tengo un servicio de entidades alojado en ArcGIS.com y lo he añadido a un mapa web de ArcGIS.com.  Cuando le indico que cree etiquetas, el campo de fecha de mis atributos no aparece como opción.

¿Se puede etiquetar el campo de fecha o solo los campos de texto?

Thanks Kelly.

I am consuming my WebMap in a Javascript app, and it appears I have an option is to do client-side labeling using labelingInfo with LabelClass or a LabelLayer, but similar to ArcGIS Online, both methods display the Date part of the date_time field.  Do you have any suggestion or work around for labeling client-side Javascript app?

Regards,

Roman

// Label Class

var labelClass = new LabelClass({
  labelExpression: '[date_time]',       <=  no REST API formatting of label?
  labelPlacement: 'always-horizontal',
});

var labelingInfos= []

labelingInfos.push(labelClass)

layer.setLabelingInfo(labelingInfos);

// Label Layer

var textColor = new Color("red");

var textLabel = new TextSymbol().setColor(textColor);

textLabel.font.setSize("14pt");

textLabel.font.setFamily("arial");

textLabelRenderer = new SimpleRenderer(textLabel);

var labels = new LabelLayer({

id: "labels"

});

labels.addFeatureLayer(layer, textLabelRenderer, "${date_time}");   <= no info windows template date formatting?

map.addLayer(labels);

Hi Roman,

Currently this functionality is not available in ArcGIS Online.

Hi Kelly,

I am having a similar issue as Dan, and I have manually type in the DateTime field name in the create labels Text box, as you have suggested.  But, the label only display the Date value and not the Time value, example: only 5/1/2015 display in the label for datetime value 5/1/2015 10:00:00.  How do I format the DateTime value to have it display correctly?

Thanks,

Roman
