Min/Max Zoom on view

NachiChidambaram — Sat, 11 Nov 2017 00:10:51 GMT

I am trying to set the following properties on the view (arcgis api 4.5)

effectiveMinZoom

effectiveMaxZoom.

So that I can set the max and min allowed zoom level . For some reason I don't see any errors and the min and max zoom levels are not set.

I also tried minZoom and maxZoom. No luck

Here is my code :

var map = new Map({
basemap: "hybrid"
});

// map.add(transportationLyr);

        var view = new MapView({
            container: "viewDiv", // Reference to the DOM node that will contain the view
            map: map,               // References the map object created in step 3
            zoom: 12,
           effectiveMaxZoom: 15,
           effectiveMinZoom: 10,
            center: [-82.78,35.0],
            padding:{
                right:320
                }
            });

Nachi,

Looks like you need to be looking at view constraints. minScale and maxScale are properties of the constraints property of the MapView.

This worked for me

this.view.constraints = {

minZoom: 9

};

Is it possible to show marker based on zoom level (something like as we zoom in more points are visible).

So that they are not overlapping when zoom out too far and looks clean on map view ?
