graphicsUtils in 4.6 ??

DerekLoi · ‎02-20-2018

I am trying to get the extent of my GraphicsLayer which contains a Point and a Polygon so I can zoom into on the map.

I don't see any mention of graphicsUtils in the 4.6 API ... then I came across this migration matrix...

Functionality matrix | ArcGIS API for JavaScript 4.6

So when is graphicsUtils coming again?

or is there another way to get the extent of all the graphics in a GraphicLayer?

btw... i see that there is a .goTo() method that takes an array of graphics... i've tried mapview.goTo(mygraphiclayer.graphics) ... doesn't work ... do i have to set other options?

are there any examples of using the goTo() method with an array of graphics?

Derek,

The View.goTo(mygraphiclayer.graphics); works fine for me. Here is a sample that works as well.

Robert,

I see that your example directly adds the graphics to the mapview and skips instantiating the GraphicsLayer object ... i'll try that and see how it goes... thanks
