I have a task at hand and I am not sure how to do it:
I would like to display features from a feature layer based on user input e.g 'n' features that have the high (or low) value of a user-selected indicator. Once I am able to display this set of features, I would use this set to categorize it based on certain criteria e.g. features that are above or below some national average for that indicator. This is what I believe needs to happen:
Sort data of the selected indicator in ascending (or descending) order
Select 'n' features that match the criteria.
Get the unique ids of these features.
Pass these ids as a definition expression for the featureLayer.
Select and display these features
Right now I am not sure how to sort and select 'n' features/records from the data. I'll be able to run the definition expression once I have the unique ids.
I'll appreciate it if someone can direct me to the right resource for me to accomplish this task.
