How to add markers to area polygon in Measurement tool

PaulBelew · ‎04-17-2017

I'm using dijit Measurement tool:

var fillSymbol = new SimpleFillSymbol(SimpleFillSymbol.STYLE_SOLID, new SimpleLineSymbol(SimpleLineSymbol.STYLE_SOLID, new esri.Color([255, 167, 25, 0.9]), 4), new esri.Color([255, 167, 25, 0.25]));
var lineSymbol = new SimpleLineSymbol(SimpleLineSymbol.STYLE_SOLID, new esri.Color([255, 167, 25, 0.9]), 4);
var pointSymbol = new SimpleMarkerSymbol(SimpleMarkerSymbol.STYLE_SQUARE, 10, new SimpleLineSymbol(SimpleLineSymbol.STYLE_SOLID, new esri.Color([255, 255, 255, 0.9]), 2), new esri.Color([255, 167, 25, 0.9]))

       this._measure_tool = new esri.dijit.Measurement({
               map: this.map,
               defaultAreaUnit: esri.Units.SQUARE_METERS, defaultLengthUnit: esri.Units.METERS,
               fillSymbol: fillSymbol, lineSymbol: lineSymbol, pointSymbol: pointSymbol
           }
               , constr.create("div"));
       this._measure_tool.startup();

When I draw a line to measure distance pointSymbol markers are appears at line points but its visible under the lines.

How can I make markers be above the lines?

When I draw a polygon to measure area markers is not visible.

How can I make markers visible on polygon figure?

I'm using version 3.20.

Paul,

As the widget is not designed for that you would have to add code to accomplish that. Here is a sample that does that:

The default experience for the widget is to display the measurement distance on the widget. Based on your image it looks like you are adding a tooltip. Is this correct? If so can you share the code you are using - that might help us give you advice on displaying the units correctly.

Here's a test app that shows the default behavior.

Thank you.

As I see the example is working in the same manner. If you can modify your example to show markers on polygon figure then I can do the same.
