Set min and max scale

Restrict zooming between specific scale ranges.

Use case

Data may only appear at a certain scale on a map, and may be visually lost if zooming too far in or out. Setting the minimum and maximum scales ensures the zoom extents are appropriately limited for the purposes of the map.

How to use the sample

Zoom in and out of the map. The zoom extents of the map are limited between the given minimum and maximum scales.

How it works

1. Instantiate a Map object.
2. Set the minimum and maximum scale using the minScale and maxScale properties of Map.
3. Set the map to a MapView object.
