Find min and max values of a field (column) in a feature layer

Maxycle — Wed, 11 May 2022 17:04:56 GMT

I am using ArcGIS API for Javascript in a Nuxt application and I would like to find the max and min values of a field in a feature layer hosted on ArcGIS. How to do that ?? The values for the stops for the visualVariables are hard coded and I would like them to be dynamic and take the min and max values of the field.

You can use StatisticDefinition with the query.outStatistics to get the min/max values.

You can search for "statistics" in the Sample Code page and find a number of samples including this one.
