Apply date range selector to filter indicators with data expressions

Tiff

I have custom data expressions for indicators to sum up various fields in my feature layer. The expression is written by creating a dictionary for all the fields that I want to eventually filter by through category selectors. These are all either integer or string fields, like "County Name" or "Year".

Is it possible to incorporate a date range selector that would somehow be compatible with the category selector filter actions? Since each selector's filter actions asks for a source and target field, I'm finding it difficult to figure out if this type of interaction is possible. Any thoughts appreciated, thank you!

A date selector just needs a date field to act against, so you should just be able to include a date field in the expression. Define the date field in your combinedDict object, then pull the date field in from the feature in your loop later.

If this is on Portal, you'll need to use Number to get your date to come through correctly.

var combinedDict = {
  "fields": [
    {'name': 'WATERSHED','type':'esriFieldTypeString'},
    {'name': 'GROUP_NAME','type':'esriFieldTypeString'},
    {'name': 'Weights','type':'esriFieldTypeInteger'},
    {'name': 'some_date', type: 'esriFieldTypeDate'}
  ],
  "geometryType": "",
  "features": []
}

var i = 0
for (var f in fs) {
  combinedDict.features[i++] = {
    "attributes": {
      "WATERSHED": f["WATERSHED"],
      "GROUP_NAME": f["GROUP_NAME"],
      "Weights": f["FIELD_1"] * 25 + f["FIELD_2"] * 22 + f["FIELD_3"] * f["FIELD_4"],
      some_date: Number(f['some_date'])
  }
}
var result = FeatureSet(Text(combinedDict))
return result

 Once your featureset has a date field in it, any date selector should be able to act against it.
