Legend widget not loading all layers on inital load

JayHill — Tue, 07 Mar 2017 14:02:03 GMT

When using the legend widget (esri JAPI 3.20), not all the layers show up when my map loads. I have to zoom a level first then they all show up. Any fixes?

Can you share your code, how you have initialize the Legend widget.

var legend = new Legend({
           map: map,
           layerInfos: layers,

       }, "legendDiv");

       legend.startup();

I think problem lies in my array of featurelayers being used for layerlist. I tried the legend.refresh() code but it didn't help

Wait until the map loads all your layers before adding the legend

map.on("layers-add-result", function () {
  var legend = new Legend({
    map: map,
    layerInfos: layers
  }, "legendDiv");
  legend.startup()
});‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

got it to work by adding refresh.

var legend = new Legend({
map: map,
layerInfos: layers

}, "legendDiv");
map.on ("layer-add-result", function(){
legend.refresh();
legend.startup();

})
