https://community.esri.com/t5/arcgis-javascript-maps-sdk-questions/featurefilter-with-distinct-unique-values/m-p/1166071#M77063 <P>Dear community,</P><P>We're using a feature layer that has many (up to a couple hundreds) features in the same locations (and also sharing the value of one of the attributes - location_id). We're using&nbsp;FeatureFilter to filter through the features and ideally would like to show only a single marker for each of the features on the same locations (or same value on the location_id attribute). I haven't found a way of doing this so maybe there is a hack or an attribute I'm not aware of?</P><P>Simply showing all markers wouldn't work here because our markers have drop shadows and the overlapped hundreds of points show the shadow as a big black block, which is what we're trying to avoid.</P><P>I've tried using featureReduction with a very small radius, in order to only show one marker per location, but unfortunately this was much slower (about 3x slower) and sometimes shows rendering artefacts.</P><P>Any help very much appreciated and thanks in advance!</P><P>Paulo</P> Wed, 20 Apr 2022 13:05:05 GMT PauloRicca 2022-04-20T13:05:05Z https://community.esri.com/t5/arcgis-javascript-maps-sdk-questions/featurefilter-with-distinct-unique-values/m-p/1166071#M77063 <P>Dear community,</P><P>We're using a feature layer that has many (up to a couple hundreds) features in the same locations (and also sharing the value of one of the attributes - location_id).
