Map with a single feature layer won't display a legend

DonaldLund — Fri, 25 Jul 2014 14:45:38 GMT

I have a map with a single feature layer, layered over a base map, and I can't get the javascript API to display a legend for it. If I throw in another layer, the legend displays. I'm following code example here: Legend | ArcGIS API for JavaScript. Why won't the legend display when only a single feature layer is defined? Do I have to define a dummy feature layer in order to display a legend? Is the legend widget using some kind of an array or something that requires more than one layer to be defined in order for it to work properly or display anything at all?

Any help or insights would be appreciated.

Donald,

you need to make sure that the featurelayer is actually visible on the map or it wont show in your legend. Some layers are configured to not show on a certain scale and once you zoom in/ out they start to show. Are you able to post a link to the layer that won't show?

Tim,

Thanks for the quick response.

The layer polygons are actually visible on the map, but the legend is blank. The feature layer is actually based on a county shapefile for the state of Michigan.

I am not able to share a link because of the strategic nature of the data. If I don't make any progress, perhaps I can make a layer with bogus data that I can share.

Either way, I'll be back.

Thanks again.

Are you able to post your code, just remove the sensitive information?

Sure. Here you go. And thanks.

FYI, the layer named 'waterbodies' is the one I'm using as a dummy layer that I toggle on and off. When it's on, the legend appears. When it's off the legendDiv content pane appears empty.

Donald,

After line 59 add:

if (layerInfo.length > 0) {

After line 64 add:

and replace 66 with:

map.addLayers([rivers]);

Whatever you have as your rivers layer will show up in your Legend.

Hope this answers your question.

Tim

DonaldLund — Mon, 28 Jul 2014 13:52:50 GMT

Tim, you're a genius.

It turns out I had the layerInfo.length check on in earlier versions, and may have accidentally stripped it out when posting the example code.

The real key to making this work was changing map.addLayer(rivers) to map.addLayers([rivers]). Any idea why the former won't display a legend. Seems like it's some sort of an array thing.

Re: Map with a single feature layer won't display a legend

TimWitt2 — Mon, 28 Jul 2014 13:54:31 GMT

You are right it has to do with an array. It trys to cycle through your add.Layers array, but when you don't use [], there is no array.
